[PATCH v2 0/3] (Re)enable DP/HDMI audio for RK3399 Gru

From: Brian Norris

This series fixes DP/HDMI audio for RK3399 Gru systems.

First, there was a regression with the switch to SPDIF. Patch 1 can be
taken separately as a regression fix if desired. But it's not quite so
useful (at least on Chrome OS systems) without the second part.

Second, jack detection was never upstreamed, because the hdmi-codec
dependencies were still being worked out when this platform was first
supported.

Patches cover a few subsystems. Perhaps this is something for arm-soc?

Changes in v2:
- (Un)set pinctrl, because the default assumes we're routing out to
external pins
