From: Chris Morgan <macromorgan@xxxxxxxxxxx>
Create dt-binding documentation to document rk817 codec.
Signed-off-by: Chris Morgan <macromorgan@xxxxxxxxxxx>
---
Changes in v7:
- Removed ifdef around register definitions for MFD.
- Replaced codec documentation with updates to MFD documentation.
- Reordered elements in example to comply with upstream rules.
- Added binding update back for Odroid Go Advance as requested.
- Submitting patches from gmail now.
Changes in v6:
- Included additional project maintainers for correct subsystems.
- Removed unneeded compatible from DT documentation.
- Removed binding update for Odroid Go Advance (will do in seperate series).
Changes in v5:
- Move register definitions from rk817_codec.h to main rk808.h register
definitions.
- Add volatile register for codec bits.
- Add default values for codec bits.
- Removed of_compatible from mtd driver (not necessary).
- Switched to using parent regmap instead of private regmap for codec.
Changes in v4:
- Created set_pll() call.
- Created user visible gain control in mic.
- Check for return value of clk_prepare_enable().
- Removed duplicate clk_prepare_enable().
- Split DT documentation to separate commit.
Changes in v3:
- Use DAPM macros to set audio path.
- Updated devicetree binding (as every rk817 has this codec chip).
- Changed documentation to yaml format.
- Split MFD changes to separate commit.
Changes in v2:
- Fixed audio path registers to solve some bugs.
