gpio: turris_omnia_mcu: Fix registering gpios

2022-09-26T08:04:37Z

Currently all GPIOs supported by CMD_EXT_CONTROL/CMD_GET_EXT_CONTROL_STATUS commands (last 16 GPIOs) are available only when FEAT_PERIPH_MCU feature bit is set. So do not register these GPIOs by U-Boot driver when this feature bit is not set, so U-Boot 'gpio' command would see only GPIOs which really exists.

gpio: turris_omnia_mcu: Fix usage of CMD_EXT_CONTROL

2022-08-09T06:57:23Z

CMD_GENERAL_CONTROL takes two 8-bit arguments but CMD_EXT_CONTROL takes two 16-bit arguments. Fix this issue and change CMD_EXT_CONTROL arguments to 16-bit. Fixes: 5e4d24ccc115 ("gpio: Add Turris Omnia MCU driver") Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese

gpio: fix incorrect depends on for SPL_GPIO_HOG

2022-08-04T19:32:20Z

Since commit 83061dbd1c89 ("Rename GPIO_SUPPORT to GPIO"), SPL_GPIO_SUPPORT has been renamed to SPL_GPIO, meaning that SPL_GPIO_HOG can never be enabled. Let's fix this by using the proper name for the Kconfig option. Fixes: 1d99e673c752 ("gpio: Enable hogging support in SPL") Cc: Quentin Schulz Signed-off-by: Quentin Schulz Reviewed-by: Simon Glass
