Because those pinctrl IP-cores on all modern Exynos chips look very similar, even if you compare the downstream code. If EXYNOS850 prefix looks confusing, maybe it can be renamed to EXYNOS9 or something like that. Those filter parameters are also present in Exynos850 downstream kernel code. So I just feel like the proper way to add that feature would be to add that also for all modern ARM64 Exynos variants while at it. > /** > * struct exynos_weint_data: irq specific data for all the wakeup interrupts > * generated by the external wakeup interrupt controller. > diff --git a/drivers/pinctrl/samsung/pinctrl-samsung.c b/drivers/pinctrl/samsung/pinctrl-samsung.c > index 449f8109d8b5..12176f98440d 100644 > --- a/drivers/pinctrl/samsung/pinctrl-samsung.c > +++ b/drivers/pinctrl/samsung/pinctrl-samsung.c > @@ -1321,6 +1321,8 @@ static const struct of_device_id samsung_pinctrl_dt_match[] = { > .data = &exynosautov9_of_data }, > { .compatible = "tesla,fsd-pinctrl", > .data = &fsd_of_data }, > + { .compatible = "google,gs101-pinctrl", > + .data = &gs101_of_data }, > #endif > #ifdef CONFIG_PINCTRL_S3C64XX > { .compatible = "samsung,s3c64xx-pinctrl", > diff --git a/drivers/pinctrl/samsung/pinctrl-samsung.h b/drivers/pinctrl/samsung/pinctrl-samsung.h > index de2ca8e8b378..e62e909fb10d 100644 > --- a/drivers/pinctrl/samsung/pinctrl-samsung.h > +++ b/drivers/pinctrl/samsung/pinctrl-samsung.h > @@ -374,6 +374,7 @@ extern const struct samsung_pinctrl_of_match_data exynos7885_of_data; > extern const struct samsung_pinctrl_of_match_data exynos850_of_data; > extern const struct samsung_pinctrl_of_match_data exynosautov9_of_data; > extern const struct samsung_pinctrl_of_match_data fsd_of_data; > +extern const struct samsung_pinctrl_of_match_data gs101_of_data; > extern const struct samsung_pinctrl_of_match_data s3c64xx_of_data; > extern const struct samsung_pinctrl_of_match_data s3c2412_of_data; > extern const struct samsung_pinctrl_of_match_data s3c2416_of_data; > -- > 2.42.0.655.g421f12c284-goog >
