Then in a new patch you can make the changes where a detailed review is needed. > --- > drivers/pinctrl/pinctrl-lantiq.h | 8 + > drivers/pinctrl/pinctrl-xway.c | 1125 ++++++++++++++++++++++++++++++++++---- > 2 files changed, 1030 insertions(+), 103 deletions(-) > > diff --git a/drivers/pinctrl/pinctrl-lantiq.h b/drivers/pinctrl/pinctrl-lantiq.h > index eb89ba0..e137d13 100644 > --- a/drivers/pinctrl/pinctrl-lantiq.h > +++ b/drivers/pinctrl/pinctrl-lantiq.h > @@ -162,6 +162,14 @@ enum ltq_pin { > GPIO53, > GPIO54, > GPIO55, > + GPIO56, > + GPIO57, > + GPIO58, > + GPIO59, > + GPIO60, /* 60 */ > + GPIO61, > + GPIO62, > + GPIO63, > > GPIO64, > GPIO65, What is the advantage of using this enum compared to just use integers directly?

Why not use one static entry for each SoC and reference it directly. Something like this: static struct pinctrl_xway_soc pinctrl_xrx300 = { XRX300_MAX_PIN, xrx300_mfp, xrx300_grps, ARRAY_SIZE(xrx300_grps), xrx300_funcs, ARRAY_SIZE(xrx300_funcs), xrx300_exin_pin_map, 5 }; Then you can just do this: { .compatible = "lantiq,pinctrl-xrx300", .data = &pinctrl_xrx300}, > {}, > }; > MODULE_DEVICE_TABLE(of, xway_match); > Hauke -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Was it intentionally that GPIO64 has the number 56 before? Maybe this GPIO56 - GPIO63 gap has some relation to the xRX100 (aka ar9) SoC, which has 3 1/2 GPIO Ports of 16bits (GPIO0 - GPIO55). > > > diff --git a/drivers/pinctrl/pinctrl-xway.c > b/drivers/pinctrl/pinctrl-xway.c > > index ae724bd..234d3f4 100644 > > --- a/drivers/pinctrl/pinctrl-xway.c > > +++ b/drivers/pinctrl/pinctrl-xway.c > > @@ -7,6 +7,7 @@ > > * publishhed by the Free Software Foundation. > > * > > * Copyright (C) 2012 John Crispin <blogic@openwrt.org> > > + * Copyright (C) 2015 Martin Schiller <mschiller@tdt.de> > > */ > > > > #include <linux/err.h> > > @@ -24,7 +25,7 @@ > > > > #include <lantiq_soc.h> > > > > -/* we have 3 1/2 banks of 16 bit each */ > > +/* we have up to 4 banks of 16 bit each */ > > #define PINS16 > > #define PORT33 > > #define PORT(x)(x / PINS) > > @@ -35,7 +36,7 @@ > > #define MUX_ALT10x2 > > > > /* > > - * each bank has this offset apart from the 1/2 bank that is mixed > into the > > + * each bank has this offset apart from the 4th bank that is mixed > into the > > * other 3 ranges > > */ > > #define REG_OFF0x30 > > @@ -51,7 +52,7 @@ > > #define GPIO_PUDSEL(p)(GPIO_BASE(p) + 0x1c) > > #define GPIO_PUDEN(p)(GPIO_BASE(p) + 0x20) > > > > -/* the 1/2 port needs special offsets for some registers */ > > +/* the 4th port needs special offsets for some registers */ > > #define GPIO3_OD(GPIO_BASE(0) + 0x24) > > #define GPIO3_PUDSEL(GPIO_BASE(0) + 0x28) > > #define GPIO3_PUDEN(GPIO_BASE(0) + 0x2C) > > @@ -80,17 +81,18 @@ > > #define FUNC_MUX(f, m)\ > > { .func = f, .mux = XWAY_MUX_##m, } > > (snip) > > /* --------- pinconf related code --------- */ > > static int xway_pinconf_get(struct pinctrl_dev *pctldev, > > unsigned pin, > > @@ -695,9 +1593,6 @@ static struct gpio_chip xway_chip = { > > > > > > /* --------- register the pinctrl layer --------- */ > > -static const unsigned xway_exin_pin_map[] = {GPIO0, GPIO1, GPIO2, > GPIO39, GPIO46, GPIO9}; > > -static const unsigned ase_exin_pins_map[] = {GPIO6, GPIO29, GPIO0}; > > - > > static struct pinctrl_xway_soc { > > int pin_count; > > const struct ltq_mfp_pin *mfp; > > @@ -708,21 +1603,41 @@ static struct pinctrl_xway_soc { > > const unsigned *exin; > > unsigned int num_exin; > > } soc_cfg[] = { > > -/* legacy xway */ > > +/* legacy xway (DEPRECATED: Use XWAY DANUBE Family) */ > > {XWAY_MAX_PIN, xway_mfp, > > xway_grps, ARRAY_SIZE(xway_grps), > > -danube_funcs, ARRAY_SIZE(danube_funcs), > > +legacy_danube_funcs, ARRAY_SIZE(legacy_danube_funcs), > > xway_exin_pin_map, 3}, > > What is the difference between this entry and the new danube entry?

We could simply match the old "lantiq,pinctrl-xway" compatible string to the new danube entry, when we also add the old "spi" mux group (DEPRECATED in the ase code) here too. > > > -/* xway xr9 series */ > > +/* xway xr9 series (DEPRECATED: Use XWAY xRX100/xRX200 Family) */ > > {XR9_MAX_PIN, xway_mfp, > > xway_grps, ARRAY_SIZE(xway_grps), > > xrx_funcs, ARRAY_SIZE(xrx_funcs), > > xway_exin_pin_map, 6}, > > -/* xway ase series */ > > -{XWAY_MAX_PIN, ase_mfp, > > +/* XWAY AMAZON Family */ > > +{ASE_MAX_PIN, ase_mfp, > > ase_grps, ARRAY_SIZE(ase_grps), > > ase_funcs, ARRAY_SIZE(ase_funcs), > > -ase_exin_pins_map, 3}, > > +ase_exin_pin_map, 3}, > > +/* XWAY DANUBE Family */ > > +{DANUBE_MAX_PIN, danube_mfp, > > +danube_grps, ARRAY_SIZE(danube_grps), > > +danube_funcs, ARRAY_SIZE(danube_funcs), > > +danube_exin_pin_map, 3}, > > +/* XWAY xRX100 Family */ > > +{XRX100_MAX_PIN, xrx100_mfp, > > +xrx100_grps, ARRAY_SIZE(xrx100_grps), > > +xrx100_funcs, ARRAY_SIZE(xrx100_funcs), > > +xrx100_exin_pin_map, 6}, > > +/* XWAY xRX200 Family */ > > +{XRX200_MAX_PIN, xrx200_mfp, > > +xrx200_grps, ARRAY_SIZE(xrx200_grps), > > +xrx200_funcs, ARRAY_SIZE(xrx200_funcs), > > +xrx200_exin_pin_map, 6}, > > +/* XWAY xRX300 Family */ > > +{XRX300_MAX_PIN, xrx300_mfp, > > +xrx300_grps, ARRAY_SIZE(xrx300_grps), > > +xrx300_funcs, ARRAY_SIZE(xrx300_funcs), > > +xrx300_exin_pin_map, 5}, > > }; > > > > static struct pinctrl_gpio_range xway_gpio_range = { > > @@ -734,6 +1649,10 @@ static const struct of_device_id xway_match[] = > { > > { .compatible = "lantiq,pinctrl-xway", .data = &soc_cfg[0]}, > > { .compatible = "lantiq,pinctrl-xr9", .data = &soc_cfg[1]}, > > { .compatible = "lantiq,pinctrl-ase", .data = &soc_cfg[2]}, > > +{ .compatible = "lantiq,pinctrl-danube", .data = &soc_cfg[3]}, > > +{ .compatible = "lantiq,pinctrl-xrx100", .data = &soc_cfg[4]}, > > +{ .compatible = "lantiq,pinctrl-xrx200", .data = &soc_cfg[5]}, > > +{ .compatible = "lantiq,pinctrl-xrx300", .data = &soc_cfg[6]}, > > Using pointers to an array elemnt here looks error prone to me.

This patch introduces new dedicated "lantiq,pinctrl-<chip>" devicetree bindings, where <chip> is one of "ase", "danube", "xrx100", "xrx200" or "xrx300" and marks the "lantiq,pinctrl-xway" and "lantiq,pinctrl-xr9" bindings as DEPRECATED. Based on the newest Lantiq Hardware Description it turend out, that there are some differences in the GPIO alternative functions of the Danube, xRX100 and xRX200 families, which makes it impossible to use only one xway_mfp table. This patch also adds support for the xRX300 family.
