Add support for configuring pins as input to the rockchip pinctrl driver. This is required for example for devices which use non-standard configurations for gpio interrupts, specifically for the light/proximity sensor on the RK3399 powered PinePhone Pro (which will be coming upstream in a future patch series). Due to the complicated layout of the RK pinctrl/gpio drivers, some extra work is required to handle deferring the GPIO configuration. On RK3399 the pinctrl driver always probes before the GPIO controller driver, so the PIN_CONFIG_OUTPUT and PIN_CONFIG_INPUT_ENABLE params both have to be deferred, this series also reworks the deferred pin handling to be generic and support any param rather than only the PIN_CONFIG_OUTPUT param. --- Caleb Connolly (4): pinctrl/rockchip: support deferring other gpio params pinctrl/rockchip: support setting input-enable param gpio/rockchip: handle deferring input-enable pinconfs arm64: dts: rockchip: rk3399: add an input enable pinconf arch/arm64/boot/dts/rockchip/rk3399.dtsi | 16 ++++++ drivers/gpio/gpio-rockchip.c | 29 ++++++++--- drivers/pinctrl/pinctrl-rockchip.c | 64 +++++++++++++++--------- drivers/pinctrl/pinctrl-rockchip.h | 7 ++- 4 files changed, 81 insertions(+), 35 deletions(-) -- 2.35.1
