63ff545af7 gpio/rockchip: fix refcount leak in rockchip_gpiolib_register()
The node returned by of_get_parent() with refcount incremented,
of_node_put() needs be called when finish using it. So add it in the
end of of_pinctrl_get().

8ea8af6c84 gpio: rockchip: request GPIO mux to pinctrl when setting direction
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.

b871656aa4 pinctrl: rockchip: Enhance support for IRQ_TYPE_EDGE_BOTH
Switching between falling/rising edges for IRQ_TYPE_EDGE_BOTH on pins that
require debounce can cause the device to lose events due to a desync
between pin state and irq type.

This problem is resolved by switching between IRQ_TYPE_LEVEL_LOW and
IRQ_TYPE_LEVEL_HIGH instead.

7920af5c82 gpio: rockchip: Reset int_bothedge when changing trigger
With v2 hardware, an IRQ can be configured to trigger on both edges via
a bit in the int_bothedge register. Currently, the driver sets this bit
when changing the trigger type to IRQ_TYPE_EDGE_BOTH, but fails to reset
this bit if the trigger type is later changed to something else. This
causes spurious IRQs, and when using gpio-keys with wakeup-event-action
set to EV_ACT_(DE)ASSERTED, those IRQs translate into spurious wakeups.

0f562b7de9 gpio/rockchip: extended debounce support is only available on v2
The gpio driver runs into issues on v1 gpio blocks, as the db_clk
and the whole extended debounce support is only ever defined on v2.
So checking for the IS_ERR on the db_clk is not enough, as it will
be NULL on v1.

Fix this by adding the needed condition for v2 first before checking
the existence of the db_clk.

This caused my rk3288-veyron-pinky to enter a reboot loop when it
tried to enable the power-key as adc-key device.
