[PATCH 0/3] ARM64: dts: meson-axg: first round of daughter card updates

[Jerome Brunet]

This patchset adds a speaker amplifier and some leds present on daughter
cards which are connected to the s400 board.

Kevin, please note that the bindings documentation update for the tas5707
has been queued for next in Mark Brown's ASoC tree. Not having it won't
break anything but you may get checkpatch warning.

[PATCH 2/3] ARM64: dts: meson-axg: add s400 main 12v supply

[Jerome Brunet]

Add a fixed regulator for the main 12v which is the main power supply
of the board.

[PATCH 3/3] ARM64: dts: meson-axg: add s400 speaker amplifier

[Jerome Brunet]

Add the first of the two tas5707 power amplifier present on the
speaker daughter board.

According to the schematics of the S400 v3, only I2SB_DIN3 and
I2SC_DOUT2 will be available to the speaker board.

9R83, 9R84 and 9R18 are not connected so no audio signal will be
provided to the second amplifier. There is no point in enabling it
even if it is visible on the i2c bus.
