You've provided no justification why the PLL driver can't reach the same setting for 48k. The setting below is just the crude part. the fine tuning is done done with the frac parameter so I doubt this provides a more accurate rate. > > Signed-off-by: Jan Dakinevich <jan.dakinevich@salutedevices.com> > --- > drivers/clk/meson/a1-pll.c | 8 ++++---- > 1 file changed, 4 insertions(+), 4 deletions(-) > > diff --git a/drivers/clk/meson/a1-pll.c b/drivers/clk/meson/a1-pll.c > index 4325e8a6a3ef..00e06d03445b 100644 > --- a/drivers/clk/meson/a1-pll.c > +++ b/drivers/clk/meson/a1-pll.c > @@ -74,9 +74,9 @@ static struct clk_regmap fixed_pll = { > }, > }; > > -static const struct pll_mult_range hifi_pll_mult_range = { > - .min = 32, > - .max = 64, > +static const struct pll_params_table hifi_pll_params_table[] = { > + PLL_PARAMS(128, 5), > + { }, > }; > > static const struct reg_sequence hifi_init_regs[] = { > @@ -124,7 +124,7 @@ static struct clk_regmap hifi_pll = { > .shift = 6, > .width = 1, > }, > - .range = &hifi_pll_mult_range, > + .table = hifi_pll_params_table, > .init_regs = hifi_init_regs, > .init_count = ARRAY_SIZE(hifi_init_regs), > },

Yet it is another set to maintain. I'd much prefer if you put the axg-audio macro in a header a re-used those. There would a single set to maintain. You may then specialize the included in the driver C file, to avoid redundant parameters Rework axg-audio to use clk_parent_data if you must, but not in the same series please. > + > +static const struct clk_parent_data a1_pclk_pdata[] = { > + { .fw_name = "pclk", }, > +}; > + > +AUDIO_GATE(audio_ddr_arb, AUDIO_CLK_GATE_EN0, 0, a1_pclk_pdata); > +AUDIO_GATE(audio_tdmin_a, AUDIO_CLK_GATE_EN0, 1, a1_pclk_pdata); > +AUDIO_GATE(audio_tdmin_b, AUDIO_CLK_GATE_EN0, 2, a1_pclk_pdata); > +AUDIO_GATE(audio_tdmin_lb, AUDIO_CLK_GATE_EN0, 3, a1_pclk_pdata); > +AUDIO_GATE(audio_loopback, AUDIO_CLK_GATE_EN0, 4, a1_pclk_pdata); > +AUDIO_GATE(audio_tdmout_a, AUDIO_CLK_GATE_EN0, 5, a1_pclk_pdata); > +AUDIO_GATE(audio_tdmout_b, AUDIO_CLK_GATE_EN0, 6, a1_pclk_pdata); > +AUDIO_GATE(audio_frddr_a, AUDIO_CLK_GATE_EN0, 7, a1_pclk_pdata); > +AUDIO_GATE(audio_frddr_b, AUDIO_CLK_GATE_EN0, 8, a1_pclk_pdata); > +AUDIO_GATE(audio_toddr_a, AUDIO_CLK_GATE_EN0, 9, a1_pclk_pdata); > +AUDIO_GATE(audio_toddr_b, AUDIO_CLK_GATE_EN0, 10, a1_pclk_pdata); > +AUDIO_GATE(audio_spdifin, AUDIO_CLK_GATE_EN0, 11, a1_pclk_pdata); > +AUDIO_GATE(audio_resample, AUDIO_CLK_GATE_EN0, 12, a1_pclk_pdata); > +AUDIO_GATE(audio_eqdrc, AUDIO_CLK_GATE_EN0, 13, a1_pclk_pdata); > +AUDIO_GATE(audio_audiolocker, AUDIO_CLK_GATE_EN0, 14, a1_pclk_pdata); This is what I mean by redundant parameter ^ > + > +AUDIO_GATE(audio2_ddr_arb, AUDIO2_CLK_GATE_EN0, 0, a1_pclk_pdata); > +AUDIO_GATE(audio2_pdm, AUDIO2_CLK_GATE_EN0, 1, a1_pclk_pdata); > +AUDIO_GATE(audio2_tdmin_vad, AUDIO2_CLK_GATE_EN0, 2, a1_pclk_pdata); > +AUDIO_GATE(audio2_toddr_vad, AUDIO2_CLK_GATE_EN0, 3, a1_pclk_pdata); > +AUDIO_GATE(audio2_vad, AUDIO2_CLK_GATE_EN0, 4, a1_pclk_pdata); > +AUDIO_GATE(audio2_audiotop, AUDIO2_CLK_GATE_EN0, 7, a1_pclk_pdata); > + > +static const struct clk_parent_data a1_mst_pdata[] = { > + { .fw_name = "dds_in" }, > + { .fw_name = "fclk_div2" }, > + { .fw_name = "fclk_div3" }, > + { .fw_name = "hifi_pll" }, > + { .fw_name = "xtal" }, > +}; > + > +#define AUDIO_MST_MCLK(_name, _reg) \ > + AUDIO_MUX(_name##_mux, (_reg), 0x7, 24, a1_mst_pdata); \ > + AUDIO_DIV(_name##_div, (_reg), 0, 16, \ > + AUDIO_PDATA(_name##_mux)); \ > + AUDIO_GATE(_name, (_reg), 31, AUDIO_PDATA(_name##_div)) > + > +AUDIO_MST_MCLK(audio_mst_a_mclk, AUDIO_MCLK_A_CTRL); > +AUDIO_MST_MCLK(audio_mst_b_mclk, AUDIO_MCLK_B_CTRL); > +AUDIO_MST_MCLK(audio_mst_c_mclk, AUDIO_MCLK_C_CTRL); > +AUDIO_MST_MCLK(audio_mst_d_mclk, AUDIO_MCLK_D_CTRL); > +AUDIO_MST_MCLK(audio_spdifin_clk, AUDIO_CLK_SPDIFIN_CTRL); > +AUDIO_MST_MCLK(audio_eqdrc_clk, AUDIO_CLK_EQDRC_CTRL); > + > +AUDIO_MUX(audio_resample_clk_mux, AUDIO_CLK_RESAMPLE_CTRL, 0xf, 24, > + a1_mst_pdata); > +AUDIO_DIV(audio_resample_clk_div, AUDIO_CLK_RESAMPLE_CTRL, 0, 8, > + AUDIO_PDATA(audio_resample_clk_mux)); > +AUDIO_GATE(audio_resample_clk, AUDIO_CLK_RESAMPLE_CTRL, 31, > + AUDIO_PDATA(audio_resample_clk_div)); > + > +AUDIO_MUX(audio_locker_in_clk_mux, AUDIO_CLK_LOCKER_CTRL, 0xf, 8, > + a1_mst_pdata); > +AUDIO_DIV(audio_locker_in_clk_div, AUDIO_CLK_LOCKER_CTRL, 0, 8, > + AUDIO_PDATA(audio_locker_in_clk_mux)); > +AUDIO_GATE(audio_locker_in_clk, AUDIO_CLK_LOCKER_CTRL, 15, > + AUDIO_PDATA(audio_locker_in_clk_div)); > + > +AUDIO_MUX(audio_locker_out_clk_mux, AUDIO_CLK_LOCKER_CTRL, 0xf, 24, > + a1_mst_pdata); > +AUDIO_DIV(audio_locker_out_clk_div, AUDIO_CLK_LOCKER_CTRL, 16, 8, > + AUDIO_PDATA(audio_locker_out_clk_mux)); > +AUDIO_GATE(audio_locker_out_clk, AUDIO_CLK_LOCKER_CTRL, 31, > + AUDIO_PDATA(audio_locker_out_clk_div)); > + > +AUDIO_MST_MCLK(audio2_vad_mclk, AUDIO2_MCLK_VAD_CTRL); > +AUDIO_MST_MCLK(audio2_vad_clk, AUDIO2_CLK_VAD_CTRL); > +AUDIO_MST_MCLK(audio2_pdm_dclk, AUDIO2_CLK_PDMIN_CTRL0); > +AUDIO_MST_MCLK(audio2_pdm_sysclk, AUDIO2_CLK_PDMIN_CTRL1); > + > +#define AUDIO_MST_SCLK(_name, _reg0, _reg1, _pdata) \ > + AUDIO_GATE(_name##_pre_en, (_reg0), 31, (_pdata)); \ > + AUDIO_SCLK_DIV(_name##_div, (_reg0), 20, 10, 0, 0, \ > + AUDIO_PDATA(_name##_pre_en), true); \ > + AUDIO_GATE(_name##_post_en, (_reg0), 30, \ > + AUDIO_PDATA(_name##_div)); \ > + AUDIO_TRIPHASE(_name, (_reg1), 1, 0, 2, 4, \ > + AUDIO_PDATA(_name##_post_en)) > + Again, I'm not a fan of this many levels of macro.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not.

This patch is based on ad402's schematics and on experience > with our own hardware (which is very close to reference board); Thanks for your serie, it's nice you're working on upstreaming this feature. In my opinion it's fine to have a "big" initial serie if you're not sure if your changes are ok, but next time add the RFC tag so we know it's not a final changeset and you seek advices. Overall the code is clean and your patch order makes sense if they were meant to be applied by a single maintainer, but in this case it will be split into multiple subsystems so it's better to split them as Jerome explained to ease review and the maintainers process. Don't hesitate discussing with us in the #linux-amlogic IRC channel on Libera.Chat, the goal is to reduce the number of patch version and ease the review and maintainance process. Concerning the link-name property, I think it should be done afterwards since it's not necessary to support audio on A1, and I think it could be extended to other SoC boards (which would be a great feature).

However, there are two issues. First, indeed, I could just extend the range of multipliers to 1..255. But I am unsure if hifi_pll is able to handle whole range of mulptipliers. The value 128 is taken from Amlogic's branch, and I am pretty sure that it works. Second, unfortunately frac parameter currently doesn't work. When frac is used enabling of hifi_pll fails in meson_clk_pll_wait_lock(). I see it when try to use 44100Hz and multipliers' range is set to 1..255. So, support of other rates than 48k requires extra effort. >> >> Signed-off-by: Jan Dakinevich <jan.dakinevich@salutedevices.com> >> --- >> drivers/clk/meson/a1-pll.c | 8 ++++---- >> 1 file changed, 4 insertions(+), 4 deletions(-) >> >> diff --git a/drivers/clk/meson/a1-pll.c b/drivers/clk/meson/a1-pll.c >> index 4325e8a6a3ef..00e06d03445b 100644 >> --- a/drivers/clk/meson/a1-pll.c >> +++ b/drivers/clk/meson/a1-pll.c >> @@ -74,9 +74,9 @@ static struct clk_regmap fixed_pll = { >> }, >> }; >> >> -static const struct pll_mult_range hifi_pll_mult_range = { >> - .min = 32, >> - .max = 64, >> +static const struct pll_params_table hifi_pll_params_table[] = { >> + PLL_PARAMS(128, 5), >> + { }, >> }; >> >> static const struct reg_sequence hifi_init_regs[] = { >> @@ -124,7 +124,7 @@ static struct clk_regmap hifi_pll = { >> .shift = 6, >> .width = 1, >> }, >> - .range = &hifi_pll_mult_range, >> + .table = hifi_pll_params_table, >> .init_regs = hifi_init_regs, >> .init_count = ARRAY_SIZE(hifi_init_regs), >> }, > >

Apparently, it was meaningless even before my modifications (the hardware has single register regardless of max_register declaration) and it should be dropped. But, is it okay to remove it in the same commit?

Yes, I could use SND_SOC_DAPM_SUPPLY, but it supports only raw values, and doesn't supports enums. Here, I want to use enum to restrict possible values, because only these values mentioned in the documentation that I have.

If you don't mind, I will send this change in a separate patch series. Although I don't have support for all boards in the linux-amlogic, I can test it on some Khadas and Odroid boards on my side.

This is not what I'm pointing out According to the datasheet - the range is 32 - 64, as currently set in the driver. The change you have provided request a multipler of 128/5 = 25,6 If you put assigned-rate = 614400000 in DT, I see no reason can find the same solution on its own. > But I am unsure if hifi_pll is able to handle whole range of > mulptipliers.

That parameter should be removed with a proper comment explaining why you are disabling it.

But, > is it okay to remove it in the same commit? Yes it has a single register, for now. Still the stride is 4. And assuming the mmio region passed from DT is correct, I'm not sure the hunk is useful at all.

This commit introduces support for capturing from it. This is mis-leading. It does not look like the change is A1 specific but rather a extension of the support for t9015. It also mixes several different topics like line configuration, capture support, etc ... Again, the t9015 changes should be a separated series from the rest, and there should be one patch per topic. As Mark, if something is meant to be configured based on the HW layout, then there a good change a kcontrol is not appropriate, and this should rather be part of the platform description, like DT.

I don't know why 32..64 range was declared for this clock, and whether it would be safe to extend it and include 128, which is required for 48kHz.

Some bits are changed comparing to existing t9015, so new compatible string is still required. Second, I don't know anything about about ADC in t9015 on other SoCs and even don't sure that it exist there (may be I am inattentive, but I'm unable to find audio input pin on sm1/g12a's pinout). > Again, the t9015 changes should be a separated series from the rest, and > there should be one patch per topic. > > As Mark, if something is meant to be configured based on the HW layout, > then there a good change a kcontrol is not appropriate, and this should > rather be part of the platform description, like DT. > > It was also suggested here: > https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/soc/meson/t9015.c?h=v6.8#n298 > Ok.

Let's start from the end: > No - Looks to me you just have two clock controllers you are trying force into one. > Again, this shows 2 devices. The one related to your 'map0' should request AUD2_CLKID_AUDIOTOP as input and enable it right away. Most of fishy workarounds that you commented is caused the fact the mmio of this clock controller is divided into two parts. Compare it with axg-audio driver, things that was part of contigous memory region (like pdm) here are moved to second region. Is this enough to make a guess that these are two devices? Concerning AUD2_CLKID_AUDIOTOP clock, as it turned out, it must be enabled before enabling of clocks from second region too. That is AUD2_CLKID_AUDIOTOP clock feeds both parts of this clock controller.

Saying you are copying it because you know it works (in your opinion) is not good enough. I'm telling you that your hack is not necessary and so far, you have not demonstrated that it is.

But that is not the goal of this commit. You argued that frac was broken and that was partly why you introduced this work around. I'm telling you this approach is incorrect. So either : * Remove frac for now, until it is fixed, because it is broken and add comment clearly explaining that quirk. * Or fix it now.

Jerome, I have reworked my driver reusing axg-audio code as most as I could and now I have one more question. Lets see on this definition from axg-audio: #define AUD_MST_MUX(_name, _reg, _flag) \ AUD_MUX(_name##_sel, _reg, 0x7, 24, _flag, \ mst_mux_parent_data, 0) #define AUD_MST_MCLK_MUX(_name, _reg) \ AUD_MST_MUX(_name, _reg, CLK_MUX_ROUND_CLOSEST) CLK_SET_RATE_PARENT is not set here. But why? It means, that topmost pll clock will not be reconfigured at runtime to satisfy the rate that was requested from axg-tdm.

But why? It means, that topmost pll > clock will not be reconfigured at runtime to satisfy the rate that was > requested from axg-tdm. > Yes, that is by design. It is another area where mainline audio differs greatly from AML vendor code. The PLLs are expected be to fixed and the audio master clock will reparent to the most adequate PLL source depending on the use case. This is how we manage to satisfy all audio interfaces with a very limited number of PLLs On AXG/G12 there is at most 6 concurrent interfaces (3 FRDDR/TODDR) - 8 on sm1 - and we can satisfy on that with 3 PLLs. That would not be possible if interfaces were having their way with the PLLs, reseting it everytime a stream is started. The PLL rate should be carefully chosen so it can be derived easily. On AXG/G12/SM1 that is: * one PLL per rate family, to maximize clock precision * x24 x32: to handle different sample sizes * x2 until we reach the PLL limits to allow higher rates such as 384kHz or even higher If you have less PLLs on A1, you'll have to make compromises, like a less precise clock to support multiple family with one PLL. This is why the PLLs are set for each platform in DT because that choice may depend on the platform use case. > > On 3/19/24 11:30, Jerome Brunet wrote: >> >> On Tue 19 Mar 2024 at 04:47, Jan Dakinevich <jan.dakinevich@salutedevices.com> wrote: >> >>> Let's start from the end: >>> >>>> No - Looks to me you just have two clock controllers you are trying >>> force into one. >>> >>>> Again, this shows 2 devices.

Yes, for us it would be better to have hifi_pll with predefined rate. For instance it will allow to avoid that ugly workaround in PDM (sysrate property, etc). But what whould be preferred for upstream? I can imagine a scenario where samples with different rate should be played, PDM attached to fclk_divN and there are no conflicts with TDM. In this case reconfiguration of hifi_pll on demand could better satisfy somebody's requirements. >> >> On 3/19/24 11:30, Jerome Brunet wrote: >>> >>> On Tue 19 Mar 2024 at 04:47, Jan Dakinevich <jan.dakinevich@salutedevices.com> wrote: >>> >>>> Let's start from the end: >>>> >>>>> No - Looks to me you just have two clock controllers you are trying >>>> force into one. >>>> >>>>> Again, this shows 2 devices.

That is another problem entirely. Krzysztof and I already covered what you should do for this. The exact rate the PDM system clock does not matter at all because the driver queries the actual rate of the clocks and adapts. You have problems here only because you added CLK_SET_RATE_PARENT and you are triggering the concurrent usage problem I explain below. > > But what whould be preferred for upstream?

The SoC has 2 TDMs which could be active concurrently a different rates. > In this case > reconfiguration of hifi_pll on demand could better satisfy somebody's > requirements. No this is not possible. Doing so does not allow all the interfaces to be used concurrently. * If the PLL is not protected, existing streams get broken by new starting stream when the PLL is reconfigured * If the PLL is protected, new stream effectively starve because no clock may provide a 'good enough' rate for them This is why the reference rate must carefully chosen, something CCF cannot do for you. For example, a source of 12.288MHz (and its powers of 2) allows to match 48 and 32kHz sample rates and approximate 44.1kHz rates with an acceptable drift. > >>> >>> On 3/19/24 11:30, Jerome Brunet wrote: >>>> >>>> On Tue 19 Mar 2024 at 04:47, Jan Dakinevich <jan.dakinevich@salutedevices.com> wrote: >>>> >>>>> Let's start from the end: >>>>> >>>>>> No - Looks to me you just have two clock controllers you are trying >>>>> force into one. >>>>> >>>>>> Again, this shows 2 devices.
