2022-10-04pinctrl: st: stop abusing of_get_named_gpio()Dmitry Torokhov
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().

There is no point to allow selecting pin-controller drivers for Qualcomm ARMv7 SoCs when building ARM64 kernel, and vice versa.

2022-10-04gpio: rockchip: request GPIO mux to pinctrl when setting directionQuentin Schulz
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.

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.

2022-09-08pinctrl: cy8c95x0: make irq_chip immutableAndy Shevchenko
Since recently, the kernel is nagging about mutable irq_chips: "not an immutable chip, please consider fixing it!" Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new helper functions and call the appropriate gpiolib functions.

GPIO library now accepts fwnode as a firmware node, so switch the driver to use it. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Link: https://lore.kernel.org/r/20220831135512.78407-1-andriy.shevchenko@linux.intel.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2022-09-03pinctrl: at91: use dev_dbg() instead of printk()Claudiu Beznea
Use dev_dbg() instead of printk(KERN_DEBUG) to avoid the following checkpatch.pl warning: "Prefer [subsystem eg: netdev]_dbg([subsystem]dev, ... then dev_dbg(dev, ... then pr_debug(... to printk(KERN_DEBUG ...".

2022-09-03pinctrl: at91: move gpio suspend/resume calls to driver's contextClaudiu Beznea
Move gpio suspend/resume execution local to driver and let it execute as close as possible to the moment the machine specific PM code is executed (by setting it to .noirq member of dev_pm_ops). With this the at91_pinctrl_gpio_suspend()/at91_pinctrl_gpio_resume() calls were removed from arch/arm/mach-at91/pm.c and also a header has been removed. The patch has been checked on sama5d3_xplained, sam9x60ek, sama5d2_xplained, sama7g5ek boards.
