Now that we can handle the generic pinctrl bindings, convert our DT to it.

Hi Maxime, Chen-Yu,

I just stumbled over this patch in Maxime's -next tree and think I
missed it before. I guess it's a bit late, but I just wanted to express
my concerns and write out the issues with the current DT approach:

Do we really want to do this? This makes the new DTs incompatible to
older kernels, for no good reasons. Or are there any? Does this "lock
muxed pins" functionality (users cannot export GPIOs which are used by a
driver) rely on the new binding?

Anyway ...
I understand that in sunxi world a kernel is always accompanied by a
matching .dtb, but we should really get away from this, as this doesn't
scale and more importantly creates big headaches in arm64 world:

1) Scaling: Providing a board .dtb together with a kernel puts the
burden of board support to each distribution, which means that _every_
distribution needs to ship matching DTs for _every_ board. There are a
lot of Allwinner boards (around 100 these days?), I am not sure every
distribution seriously wants to put every .dtb into some bootloader
accessible directory. Also this kind of defeats the original DT idea,
where the .dtb is provided by firmware and a generic kernel just works
with whatever it gets presented.
Either distributions will not support certain boards because of this or
there is a lot of maintenance churn in distros.
Yes, arm(32) has lived with this for years, but that doesn't mean we
need to keep it this way.

2) Firmware DT: We start to see more and more Allwinner boards with SPI
flash now, which is supposed to hold some firmware bits. This gives the
ultimate opportunity to store the DT in there as well. BUT this relies
on there being _one_ DT (to rule them all). I don't see issues with
older DTs not having full functionality on newer kernels (this would be
a reason for a firmware update), but there should at any given time _one
best_ DT which is a candidate for being burned into the flash.
Otherwise people are stuck with a certain kernel version (range).
As an example in this case: Kernel 4.9 is LTS and will probably be
elected by Debian to be _the_ kernel for the next release and supported
over several years. But it relies on an old style DT (allwinner,pins
properties), newer pinctrl DT nodes will be rejected by the driver.
But for new features (upcoming HDMI support for H3, for instance) to be
usable a newer DT is required, even if an old kernel will ignore those
features. So if the flash provides a new DT, we cannot boot stable
Debian, whereas if the flash provides a legacy DT, we cannot use new
features in newer kernels.
Not changing the DT in a way that breaks forward compatibility can be
done, for instance we just drop this patch here. For new SoCs (like A64
or H5, where there are no backward compatibility issues) we can happily
use the new bindings in the official DTs, but for anything already
supported by older kernels we just stick which what we have. We have to
keep the old support code in anyway.
Yes, providing both forward and backward compatibility is not going to
be a walk in the park, but is inevitable if we want to get those board
out of the toy area. Other platform can cope with this.

3) On EFI setups the generation(!) of the DT is actually done in EFI
firmware (very much like in the original PowerPC OF setup). It is
expected that the generation relies on a static DT scaffold, but
firmware is free to add or remove nodes. Providing different DTs for
each kernel is hard to integrate into this approach.

4) Generic boot images: On the x86 side everybody expects this just to
work: You put in a generic USB stick with one (or two) generic kernels
and it just boots, without this installation having to know each
supported machine beforehand. It even works with machines newer than the
distro. While the last is hard work, it can be done, but only if the DT
is provided by firmware, which requires there to be one best DT for each
board.

5) arm64: Distributions providing support for arm64 machines generally
do not seem to provide DTs, because most platform do not require them
to. It is not clear that every distribution will do so for the sake or
supporting Allwinner boards.

6) Other OSes (or U-Boot) are affected by this as well. Eventually this
will lead them to create their own DTs (and their own bindings?), which
makes this situation really a mess. We can hardly request them to stick
with the Linux bindings if we break them regularly.

7) Dynamic DT alteration (by firmware/U-Boot and using overlays, for
instance), will be much easier if the DT is originally stored in the
firmware and snippets are stored there as well. This is for instance a
use case for the (optional) WiFi module on the Pine64.

8) Those patches also create a lot of potential merge conflicts, since
they touch almost every sunxi DT file. They are trivial to solve,
probably, but still tend to create a lot of work and cause nuisance for
other people (as proven with the A64 CCU driver in this cycle).

So can I ask that we start taking this seriously and stop doing things
which prevent Allwinner boards from being supported properly?
Which would first involve dropping this very patch?
Having done breakage in the past (with "allwinner,sun7i-a20-mmc", for
instance) is no excuse for doing it again. And especially I want to
avoid this habit creeping into the arm64 world (thinking about the H5
here, which may be impacted by this very patch, for instance).

Cheers,
Andre.

The driver still supports the old binding.

I'm not sure which breakage we introduced with a new compatible: the
old compatible is working just like it used to, and the new one is
working like we need it to.

And again, if you looked at the entire serie, you would have seen that
I took this into account.

Yes, a _current_ version of the driver supports both bindings, but older
versions *require* the older binding and bail out if various
allwinner,xxx properties are missing - as in those proposed new DTs:

4.9 kernel with sunxi/for-next .dtb:
sun8i-h3-pinctrl 1c20800.pinctrl: missing allwinner,function property in
node uart0
sun8i-h3-pinctrl 1c20800.pinctrl: missing allwinner,function property in
node mmc0
sunxi-mmc: probe of 1c0f000.mmc failed with error -22

But the new compatible is not recognized with older kernels, preventing
people from using the newest DT with older kernels as well.
I proposed to simply work around this by using the old compatible as a
fallback: compatible="sun7i-a20-mmc", "sun5i-a13-mmc";
Unfortunately this suggestion was not followed.
So now we can't boot a 4.8 (or earlier) kernel with a .dtb from a 4.9 or
later tree. Adding the extra string would fix this.

Actually the recommended approach to avoid this situation in the first
place is to always use compatible strings with the SoC-specific name as
the first string, followed by the compatible string the driver works
with. And this should be done upon introducing a new DT to the tree -
even if at this point the driver doesn't deal with the new string.
Unknown strings will just be skipped.
So for instance the H5 DT should read: "sun50i-h5-mmc",
"sun50i-a64-mmc", "sun5i-a13-mmc"; (with the last string possibly being
optional). The current kernel driver will not match the h5 string, so it
falls back to the a64 string and works. If we learn about a neat eMMC
5.1 feature (or any quirk the H5 can benefit from) somewhere in the
future, we can add the code together with this h5 string to the driver
and don't need to change the DT at all.

I saw that and I appreciate that very much, but that post was not about
keeping compatibility with older DTs, but allowing older kernels to run
with the latest DT as well.
Newer DTs from your -next branch do not work with older kernels - that
is what my whole post was about. _Why_ we should care is explained there.

And please don't get me wrong: I am not asking for rewriting and bending
the whole kernel source to make this possible, it's just that we drop
this patch here, for instance, or simply not _change_ compatible names,
but instead add new strings.

Cheers,
Andre.

This is seriously getting out of control. We already come to great
length (and sometimes a painful amount of hacks) to satisfy a few
individuals with a theorical interest in backward compatibility (and
apparently, we're even the only one doing so, even more platforms
choosing to not support that as we speak), there's seriously no reason
to support forward compatibility as well. This has *never* been a
thing, never has been documented nor advertised, I don't know why it
should be one more thing to carry on our shoulders.

Only maybe to slow us even more in the process, and effectively
prevent us from doing any actual work.

When do you draw the line exactly? You could have the same argument
for any feature that will be supported in the future... Do you also
want to backport any given driver for any kernel version?

This is ridiculous. 4.9 didn't have MMC support. Who cares about
whether MMC (or any other driver) works? This was never supposed to!

And what about the situation that you encountered last week too? IE
the compatibility was introduced because it was convenient, and it
turns out it's not working as expected?

We remove the bogus compatible from the list? But then, we can't boot
anymore on older kernels...

I agree.

We have too much standardization burden to maintain already as it is.

And AFAICT the Allwinner support is a hacker/community/enthusiast
effort without vendor backing.

We should be aware that the strong push toward DT standardization
was due to mess in the vendor trees, and as for the ambition to ship
DTBs with products, that is for people producing products to do,
not for the community. Community support can very well use attached
DTB files on the kernel from my point of view, I don't see why
ArchLinuxARM and others should have to standardize and support
DTB file in flash images, very ambitious if they do but definately
not their problem.

Yours,
Linus Walleij
