[PATCH v2 0/5] Updates for Radxa ROCK Pi 4

[Alex Bee]

Hi list,

This series adds support for 2 new revisions of Radxa's ROCK Pi 4,
namely ROCK Pi 4A+ and ROCK Pi 4B+. While most things are in common
with the previous 4A and 4B revisions, they have OP1 revision of
the SoC and eMMC soldered on board.
Patch 4 and 5 add SPDIF and anlog Codec to the common device tree,
since they are in place in previous revisions as well.

There is no example (which I could find) for Rockchip on how to
deal with "+" revisions - so I looked up other SoCs and the rule
seems to be to use the "+" for the model name (which is the "offical"
name), but use "-plus" for compatible name and device tree files names
(see "Raspberry Pi Model A+", for instance).

A short node for testing ES8316 codec:
The driver disables the headphone jack by default - for testing
one would have to enable it via amixer with:
amixer [card index] 'Right Headphone Mixer Right DAC' on
amixer [card index] 'Left Headphone Mixer Left DAC' on

Changes in v2:
- added additional compatibles for the new revisions (Heiko)
- renamed ES8316 audio card name to "Analog" (Johan)
- added patch for SPDIF
- aligned spelling of board name(s)
