Subject: [PATCH 0/4] ARM: dts: aspeed: Enable ADC for wedge100 BMC

From: Tao Ren <[email protected]>

The patch series enables ADC for Facebook Wedge100 BMC platform.

Patch #1 enables ADC in Facebook AST2400 common dtsi because ADC is used
on all the Facebook AST2400 Network BMC platforms.

Patch #2 removes the redundant ADC entry from Wedge40 dts.

Patch #3 removes the redundant ADC entry from Galaxy100 dts.

Patch #4 enables the ADC voltage sensoring channels in Wedge100 dts.
