[PATCH 0/6] Add basic node support for Mediatek MT8186 SoC

[allen-kh.cheng]

From: Allen-KH Cheng <Allen-KH.Cheng@mediatek.com>

MT8186 is a SoC based on 64bit ARMv8 architecture.
It contains 6 CA55 and 2 CA78 cores.
MT8186 share many HW IP with MT65xx series.

This patchset was tested on MT8186 evaluation board to shell.

Based on v5.16-rc8

Allen-KH Cheng (6):
  dt-bindings: timer: Add compatible for Mediatek MT8186
  dt-bindings: serial: Add compatible for Mediatek MT8186
  dt-bindings: watchdog: Add compatible for Mediatek MT8186
  dt-bindings: mmc: Add compatible for Mediatek MT8186
  dt-bindings: phy: Add compatible for Mediatek MT8186
  arm64: dts: Add Mediatek SoC MT8186 dts and evaluation board and
