Merge tag 'qcom-pinctrl-6.3' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-dt into devel Qualcomm pinctrl Devicetree bindings changes for v6.3 Set of cleanups and fixes for Qualcomm pin controller bindings, to match existing DTS and correct the schema.

AT91 pinctrl deferred probing support is broken if the GPIO devices haven't probed first and set gpio_banks to non-zero. The later condition that only some GPIO devices haven't probed can't actually happen as either all the GPIO devices have probed first or none of them have. Plus the pinctrl driver has already returned -EINVAL, so it's not on the deferred list to retry probing. Fix this by consolidating the checking that all GPIO devices are probed.

The child node name patterns in Mediatek pinctrl bindings don't match reality. I don't know where '-[0-9]+$' came from, but I don't see any nodes with a matching pattern. Also, patterns such as 'pins' or 'mux' are ambiguous because any prefix or suffix is allowed. If that's desired, it should be explicit. Signed-off-by:

Yeah, while the ->add_pin_ranges() shouldn't be used by DT drivers, this one requires it to support quite old firmware descriptions that do not have gpio-ranges property. The change allows to clean up GPIO library from OF specifics. There is no functional change intended. Signed-off-by:

The ->add_pin_ranges() is supposed to be called for the backward compatiblity on Device Tree platforms or non-DT ones. Ensure that by checking presense of the "gpio-ranges" property. This allows to clean up a few existing drivers to avoid duplication of the check. Signed-off-by:
