Hello, these three patches make sure that there's an explicit dependency from the GPIO chip in Tegra SoCs to the corresponding pinctrl device, without having duplicated gpio ranges.
By having an explicit dependency, we can do things such as probing the pinctrl device before the GPIO chip device to avoid deferred probes. Thanks, Tomeu Tomeu Vizoso (3): gpio: defer probe if pinctrl cannot be found pinctrl: tegra: Only set the gpio range if needed ARM: tegra: Add gpio-ranges property arch/arm/boot/dts/tegra114.dtsi | 1 + arch/arm/boot/dts/tegra124.dtsi | 1 + arch/arm/boot/dts/tegra20.dtsi | 1 + arch/arm/boot/dts/tegra30.dtsi | 1 + drivers/gpio/gpiolib-of.c | 27 ++++++++++++++++++--------- drivers/gpio/gpiolib.c | 5 ++++- drivers/pinctrl/pinctrl-tegra.c | 19 ++++++++++++++++++- include/linux/of_gpio.h | 4 ++-- 8 files changed, 46 insertions(+), 13 deletions(-) -- 2.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
