pinctrl: rockchip: add support the get_direction
This patch adds the get_direction to support the gpio
interface.
The gpio direction is not used on rockchip platform when use the gpio
debugfs.
Tested on kylin board. (RK3036 SoCs)
The repro steps:
$/sys/class/gpio/
echo 53 > export
$/sys/class/gpio/gpio53# cat direction
in
In general, the gpio53 should be out value, but the direction is the
default value 'in', since the get_direction didn't supported in rockchip
pinctrl.
So, we should add this patch to support it.
