mvebu: pinctrl: apply SDHCI PHY config for A7K

2022-07-29T08:02:43Z

Current pin control driver applies SDHCI PHY MUX selection when board DT calls for eMMC function on MPP wires. However, for CP side eMMC, only the "armada-8k-cpm-pinctrl" compatibility string is taken into account, which causes CP-SDHCI on Armada-7K boards to fail. This patch adds "armada-7k-pinctrl" compatibility string handling for the CP-SDHCI PHY configuration case. Signed-off-by: Konstantin Porotchkin Reviewed-by: Igal Liberman Reviewed-by: Stefan Roese

arm64: a37xx: pinctrl: Implement get_pins_count, get_pin_name and get_pin_muxing functions

2022-07-29T08:02:43Z

These functions are required for 'pinmux status -a' command to print current configuration of each MPP pin. Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese

arm64: a37xx: pinctrl: Implement gpio_request_enable for gpio functionality

2022-07-29T08:02:43Z

To automatically enable GPIO functionality of some MPP pin, it is required to implement .gpio_request_enable and .gpio_disable_free callbacks in pinctrl driver and set .request and .rfree callbacks in GPIO driver to pinctrl_gpio_request / pinctrl_gpio_free functions.

mvebu: pinctrl: Add Armada 38x driver

2022-07-28T06:41:44Z

This new Armada 38x driver is based on Linux kernel driver. It can set any pin to any valid function specified in DT like Linux kernel, it provides support for 'pinmux status -a' command and also for pinctrl_gpio_request(). Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese

pinctrl: Add new function pinctrl_generic_set_state_prefix()

2022-07-28T06:41:44Z

This new function pinctrl_generic_set_state_prefix() behaves like pinctrl_generic_set_state() but it takes third string argument which is used as the prefix for each device tree string property. This is needed for Marvell pinctrl drivers, becase Linux device tree files have pinmux properties prefixed by "marvell," string. This change allows to use generic U-Boot pinctrl functions for Armada 38x pinctrl driver without need to copy+paste of the majority U-Boot pinctrl code.
