Subject: [PATCH 0/3] pinctrl: pinctrl-single: fix suspend/resume on j7200

On j7200, during suspend to ram the SoC is powered-off. So the pinctrl
contexts are lost.
The flag PCS_CONTEXT_LOSS_OFF shall be set to restore the pinctrl
contexts.

A new compatible (ti,j7200-padconf) was created to enable this flag only
for j7200.
