Subject: [PATCH v4 0/6] Fix the overlapping registers issue for the MediTek audio system

Hi,

This is the new round of the audsys. I add devm_of_platform_populate() in the clock driver
to populate the child devices (AFE) so that we can handle the dependency for all functions. 

changes since v4:
 - remove "simple-mfd" from mediatek,audsys.txt.
 - switch to use devm_of_platform_populate() to populate the child devices.
 
changes since v3:
 - Rebase to v4.16.
 - Modify clock driver for the sake of the backward compatibility.
 - Rewrite commit message of patch 4/5 to make it more specific.

changes since v2:
 - Drop useless changes in clk-mt7622-aud.c.
 - Revise binding text: 
        - Add more information about audio subsystem.
        - Separate clock node and AFE node.
 - Update license header.

changes since v1:
 - To avoid writing an MFD driver, we add "simple-mfd" in the audsys binding.
 - Move three top clocks to audio driver [1] as we remove mfd/mtk-audsys.c in 
v1.

Ryder Lee (6):
  clk: mediatek: update missing clock data for MT7622 audsys
  clk: mediatek: add devm_of_platform_populate() for MT7622 audsys
  clk: mediatek: add audsys support for MT2701
  dt-bindings: clock: mediatek: update audsys documentation to adapt MFD
    device
  dt-bindings: clock: mediatek: add audsys support for MT2701
  arm: dts: mediatek: modify audio related nodes for both MT2701 and
    MT7623
