[PATCH 0/8] ARM: mstar: Board filling out pt. 1

[Daniel Palmer]

I have had ~700 commits in my own tree for these boards
for a long time now. Display, audio etc work but this stuff
hasn't been mainlined as spliting everything out was a
nightmare and I didn't have the time.

I have an intern called Claude now and we've cleaned up
my tree so I can start pushing parts of it again.

The following are devicetree commits that do not depend
on drivers etc that are not already in mainline so can
be applied now.

Daniel Palmer (8):
  ARM: dts: mstar: unitv2: Wire up LEDs
  ARM: dts: mstar: unitv2: Add regulators
  ARM: dts: mstar: unitv2: Add button
  ARM: dts: mstar: unitv2: Link cpu to core regulator
  ARM: dts: mstar: miyoo-mini: Add vibrator
  ARM: dts: mstar: miyoo-mini: Add vbat switch
  ARM: dts: mstar: sbc2d06: Add regulators
  ARM: dts: mstar: ssd201htv2: Add SD card supply regulator
