Subject: [PATCH 0/4] rockchip: support configuring pins as input
Date: Mon, 28 Mar 2022 01:50:01 +0100 [thread overview]
Message-ID: <20220328005005.72492-1-kc@postmarketos.org> (raw)
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.
