Subject[PATCH v1 2/2] ARM: dts: rockchip: Add the OTP gpio pinctrl
Date
We need the OTP pin is gpio state before resetting the TSADC controller,
since the tshut polarity will generate a high signal.

Signed-off-by: Caesar Wang <wxt@rock-chips.com>

Changes in v1:
- As the Doug comments, drop the thermal driver patchs since
we can with pinctrl changing to work.
- As the Doug's patch to add the 'init' property.
