[PATCH 0/2] Utilize pinctrl-single for bcm7038-style chips

[Florian Fainelli]

This patch set allows Broadcom STB chips with the BCM7038-style
pinmux/configuration blocks to use pinctrl-single. This does not
preclude us from making use of a more sophisticated driver in the
future, should we need to.

Florian Fainelli (2):
  dt-bindings: pinctrl: pinctrl-single: Add brcm,bcm7038-padconf
  pinctrl: single: Add bcm7038-padconf compatible matching

Add the "brcm,bcm7038-padconf" compatible to the pinctrl-single binding.

If there is going to be a new version, entire block should be placed
before 'ti' to have some sort of sorting by compatible.

But no need to resend just for that.

[PATCH 2/2] pinctrl: single: Add bcm7038-padconf compatible matching

[Florian Fainelli]

Just like the TI J7200 padconf, we lose the context and therefore need
to save it and restore it across suspend/resume states.
