Pin descriptions for this chip only look like standard GPIO device tree descriptions, while in fact they contain additional data (in excess of number of cells specified in description of gpio controllers). They also refer to only pins/gpios belonging to the driver and not to arbitrary gpio in the system. Because we want to stop exporting OF-specific handlers from gpiolib-of, let's parse the pin reference ourself instead of trying to call of_get_named_gpio(). Signed-off-by:

There is no point to allow selecting pin-controller drivers for Qualcomm ARMv7 SoCs when building ARM64 kernel, and vice versa. This makes kernel configuration more difficult as many do not remember the Qualcomm SoCs. There won't be a single image for ARMv7 and ARMv8/9 SoCs, so no features/options are lost. Signed-off-by:

Before the split of gpio and pinctrl sections in their own driver, rockchip_set_mux was called in pinmux_ops.gpio_set_direction for configuring a pin in its GPIO function. This is essential for cases where pinctrl is "bypassed" by gpio consumers otherwise the GPIO function is not configured for the pin and it does not work. Such was the case for the sysfs/libgpiod userspace GPIO handling. Let's call pinctrl_gpio_direction_input/output when setting the direction of a GPIO so that the pinctrl core requests from the rockchip pinctrl driver to put the pin in its GPIO function.

Commit b6d09f78 ("pinctrl: nomadik: Drop U8540/9540 support") removes the DB8540 pin controller driver and its config PINCTRL_DB8540. There is some code left-over in the generic nomadik pinctrl driver, i.e., drivers/pinctrl/nomadik/pinctrl-nomadik.{ch}, that is still around for the removed DB8540 pin controller driver. Remove this remaining dead code. This issue was discovered with ./scripts/checkkconfigsymbols.py. Signed-off-by:

Merge tag 'samsung-pinctrl-6.1' of https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into devel Samsung pinctrl drivers changes for v6.1 1. Minor fix in order of initializing pinctrl driver - GPIOs should be configured before registering gpiolib. 2. Final steps to deprecated bindings headers with register constants. The constants were moved to include files in DTS directories, because these are not suitable for bindings. Remove final references and mark binding header as deprecated to warn any users.
