Subject: [alsa-devel] [PATCH v3] ASoC: codecs: Add DA9055 codec driver
This patch adds support for Dialog semiconductor's DA9055 audio codec.
This has been tested on DA9055 EVB with Samsung SMDK6410 board.

---
Changes since v2:
- Added platform data support for Mic bias voltage and source
- Used DAPM for DAC source selection
- Other minor improvements
---
Changes since v1:
- Made extensive use of DAPM throughout the driver
- Removed LDO, DMIC and other non used controls
- Corrected names for many controls
- Other minor improvements
