d82a970009 pinctrl: artpec6: constify pinconf_ops, pinctrl_ops, and pinmux_ops structures
This pinctrl_ops structure is only stored in the const pctlops
field of a pinctrl_desc structure. Make the pinctrl_ops structure
const as well.

Done with the help of Coccinelle.

2e6424ab85 pinctrl: amd: fix error return code in amd_gpio_probe()
platform_get_irq() returns an error code, but the pinctrl-amd driver
ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.

ea479996c7 pinctrl: Add pinctrl driver for the RK805 PMIC
RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.

This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.

 2. Fix invalid register offset used for external interrupts on Exynos5433.

 3. Consolidate between drivers and bindings the defines for pin mux functions.
 4. Minor code improvements.

98c01b19b8 pinctrl-st: fix of_irq_to_resource() result check
of_irq_to_resource() has recently been fixed to return negative error #'s
along with 0 in case of failure, however the ST driver still only regards
0 as failure indication -- fix it up.

48e43b3e89 pinctrl: sirf: atlas7: fix of_irq_get() error check
of_irq_get() may return  any negative error number as well as 0 on failure,
while the driver only checks for -EPROBE_DEFER, blithely continuing with
the call to gpiochip_set_chained_irqchip() -- that function expects the
parent IRQ as *unsigned int*, so would probably do nothing  when a large
IRQ number resulting from a conversion of a negative error number is passed
to it, however passing 0 would probably work but the driver won't receive
valid GPIO bank interrupts.

Check for 'ret <= 0' instead and return -ENXIO from the driver's probe iff
of_irq_get() returned 0.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.
