[PATCH 00/12] mediatek: rework audio subsystem driver

Hi all,

This patch series mainly adds a common driver [5][6] for the top block of
the MediaTek audio subsystem, which includes clock part and audio components.
This is a minimal driver that manages shared resources like shared registers,
and expose a regmap to its sub-nodes. It was tested on the bananapi-r2 and
the MT2701 EVB.

Also, this driver can be reused by other subsystems (e.g. MMSYS, ETHSYS) in
future patch.

Patch[1]-[4]: rework for audio enable/disable sequences and update some part of
code to make them more generic.
Patch[7]~[12]: modify both drivers, audio and clock to adapt the new subsystem.

ASoC: mediatek: fix error handling in mt2701_afe_pcm_dev_probe()
ASoC: mediatek: rework clock functions for MT2701
ASoC: mediatek: cleanup audio driver for MT2701
ASoC: mediatek: update clock related properties of MT2701 AFE
mfd: mtk-audsys: add MediaTek audio subsystem driver
mfd: add DT bindings for MedaiTek audio subsystem
