This is a continuation of work focused on improving the pinctrl-samsung driver. First part on which this one depends: [RFC 0/6] pinctrl: samsung: Remove static platform-specific data http://article.gmane.org/gmane.linux.kernel.samsung-soc/12759 This series attempts to simplify usage of the driver and fix several problems of current implementation, in particular: - Simplifies GPIO pin specification in device tree by using pin namespace local to pin bank instead of local to pin controller, e.g. gpios = <&gpj0 3 0>; instead of gpios = <&pinctrl0 115 0>; - Simplifies GPIO interrupt specification in device tree by using namespace local to pin bank (and equal to GPIO namespace), e.g. interrupt-parent = <&gpj0>; interrupts = <3 0>; instead of interrupt-parent = <&pinctrl0>; interrupts = <115 0>; - Simplifies internal GPIO pin to bank translation thanks to correspondence of particular GPIO chips to pin banks. This allows to remove the (costly in case of GPIO bit-banging drivers) lookup over all banks to find the one that the pin is from. Any comments are welcome. To do: - Bindings documentation - Per-bank interrupt specifiers for wake-up interrupts - Configuration of pins used as wake-up interrupts to EINT function Tomasz Figa (6): pinctrl: samsung: Hold OF node of pin bank in bank struct pinctrl: samsung: Hold pointer to driver data in bank struct pinctrl: exynos: Use one IRQ domain per pin bank pinctrl: samsung: Do not pass gpio_chip to pin_to_reg_bank pinctrl: samsung: Use one GPIO chip per pin bank ARM: dts: exynos4210: Update pin bank nodes to reflect per-bank GPIO chips and IRQ domains arch/arm/boot/dts/exynos4210-pinctrl-banks.dtsi | 72 ++++++++++ arch/arm/boot/dts/exynos4210.dtsi | 4 - drivers/pinctrl/pinctrl-exynos.c | 118 +++++------------ drivers/pinctrl/pinctrl-exynos.h | 12 -- drivers/pinctrl/pinctrl-samsung.c | 168 ++++++++++++++---------- drivers/pinctrl/pinctrl-samsung.h | 18 ++- 6 files changed, 220 insertions(+), 172 deletions(-) -- 1.7.12 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
