Subject: [PATCH v1 0/6] add "simple-mfd" support for MediaTek audio subsystem
Date: Thu, 4 Jan 2018 15:44:02 +0800	[thread overview]
Message-ID: <cover.1515038387.git.ryder.lee@mediatek.com> (raw)

Hi,

The reason for this series is that MediaTek audio hardware block expose more than
a single functionality, but register those in different kernel subsystems.
Same issue could also be found in MMSYS: https://lkml.org/lkml/2017/11/14/669

Hence use "simple-mfd" to handle this kind of situation, that will make sure all
children are registered - and we don't need to write an MFD driver specially.
It was tested on the bananapi-r2 and the MT2701/MT7622 EVB.

[1]~[3]: modify the current audio driver accordingly.
[5][6]: add clock driver for MT2701 and add missing data for MT7622.

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):
  ASoC: mediatek: add some core clocks for MT2701 AFE
  ASoC: mediatek: modify MT2701 AFE driver to adapt mfd device
  ASoC: mediatek: update MT2701 AFE documentation to adapt mfd device
  dt-bindings: clock: mediatek: add "simple-mfd" in audsys documentation
  clk: mediatek: update missing clock data for MT7622 audsys
  clk: mediatek: add audsys support for MT2701
