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  as we remove mfd/mtk-audsys.c in v1.
