Subject: [PATCH 3/8] ASoC: cs530x: Add CODEC and DAC support
From: Simon Trimmer <simont@...nsource.cirrus.com>
- Added DAC register address constants
- Add the new registers to the regmap config
- Renamed constants that are shared between the DACs and ADCs
- Add the device IDs and device names of the CODEC and DACs along with
their different capabilities
- Add DAPM widgets, ALSA controls and event handling for the DAC
functionality
- Add Playback DAI support
