Subject: [PATCH v1 2/2] ARM: dts: rockchip: Add the OTP gpio pinctrl

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@...k-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.
