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

From: Ryder Lee
Date: Tue Jan 02 2018 - 06:47:26 EST


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.

Ryder Lee (12):
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
ASoC: mediatek: modify MT2701 AFE driver to adapt subsystem wrapper
ASoC: mediatek: modify documentation to adapt subsystem wrapper
clk: mediatek: move part of mtk_clk_register_gates() to the new
function
clk: mediatek: switch to use dev_get_regmap() for MT7622 audsys
clk: mediatek: add audsys support for MT2701
dt-bindings: clock: mediatek: update audsys bindings to adapt the
wrapper
