This patchset adds support for the Ugoos AM6, an Android STB based on
the Amlogic W400 reference design with the S922X chipset.

v2: correction of minor nits

v3: address regulator and GPIO corrections from Neil Armstrong (using
schematic excerpts from Ugoos) and related v2 comments from Martin
Blumenstingle. Add acks on patches 1/2 from Rob Herring.

Christian Hewitt (3):
  dt-bindings: Add vendor prefix for Ugoos
  dt-bindings: arm: amlogic: Add support for the Ugoos AM6
  arm64: dts: meson-g12b-ugoos-am6: add initial device-tree

please move it below sdio_pwrseq (or at least somewhere below the memory node)

can we add the enable GPIO here now that we know how to describe the
VDDCPU_B regulator?

(not limited to this patch: there's a lot of redundancy with the CPU
nodes across the G12B .dts)

all nodes starting here should use alphabetical sorting
