pinctrl: fix pinctrl_gpio_get_pinctrl_and_offset for gpio-ranges array

2023-04-02T18:53:53Z

Sometimes a multi-element array is used for "gpio-ranges" property in dts file: qe_pio_e: gpio-controller@1460 { ...... gpio-ranges = <&pinctrl1 0 20 10>, <&pinctrl2 10 50 20>; ...... }; But the function pinctrl_gpio_get_pinctrl_and_offset can't handle this case because the "index" argument passed to dev_read_phandle_with_args is fixed to be "0". Use a loop to traverse the array to fix it. Signed-off-by: Quanyang Wang

pinctrl: get rid of some ifdeffery

2023-01-27T17:51:26Z

Don't define an empty version for pinconfig_post_bind(). Just guard the call and let the linker garbage collection do the rest. This way, we also don't have to do any guesswork. Signed-off-by: Michael Walle Reviewed-by: Marek Vasut

pinctrl: don't fall back to pinctrl_select_state_simple()

2023-01-27T17:51:26Z

If CONFIG_PINCTRL_FULL is enabled, never fall back to the simple implementation. pinctrl_select_state() is called for each device and it is expected to fail. A fallback to the simple imeplementation doesn't make much sense. To keep the return code consistent, we need to change the -EINVAL (which was ignored before) to -ENOSYS.

dm: pinctrl: Revert "pinctrl: probe pinctrl drivers during post-bind"

2023-01-18T18:49:13Z

This breaks chromebook_coral and it is also not how things should work. If a board needs to bind GPIOs as part of a pinctrl driver this can be done during the bind step, if needed. We cannot probe pinctrl devices when binding as a rule, since it cannot be supported on some platforms. The bind and probe steps are separate in U-Boot and they should remain separate.

pinctrl: probe pinctrl drivers during post-bind

2022-05-17T04:44:06Z

Currently, pinctrl drivers only get probed if pinconf is actually being used, however on SoC-s like Armada 3720 pinctrl driver is a also the GPIO driver. So, if the pinctrl driver doesn't get probed GPIO-s won't get registered and thus they cannot be used. This is a problem on the Methode eDPU as it just uses SB pins as GPIO-s and without them being registered networking won't work as it only has one SFP slot and the TX disable GPIO is on the SB controller. So, probe the pinctrl drivers using DM_FLAG_PROBE_AFTER_BIND like LED uclass does. Signed-off-by: Robert Marko Reviewed-by: Pali Rohár Reviewed-by: Stefan Roese
