The ASoC DAPM stereo control patches in v1 were split out and merged already. These remaining patches depend on them. The A31's internal codec is similar (in terms of DMA, interface and control layouts) to the one found in the A10/A13/A20 SoCs. However it has more external inputs and outputs, the mixer controls are now stereo (left/right separated), and it also has some audio processing features (not supported yet). Changes since v1: - Patches 1, 2, 3 and 4 were split out from patch 6. - Reworked handling of register offset differences with regmap_field, as suggested by Maxime. - Added support for an optional (in the driver) reset control (patch 5) - Added required reset control for sun6i-a31-codec - Added more comments for sun6i registers - Added HPCOM (direct drive mode) support - Renamed sun6i audio card name to "A31 Audio Codec" - Added example for allwinner,sun6i-a31-codec device tree - Fixed line out volume control scale - Added external amplifier enable GPIO for Hummingbird A31 - Added patch to enable audio codec on Sinlinx SinA31s Patch 1 moves some code around to facilitate patch 2. No code was changed Patch 2 expands the quirks to handle different register offsets for - ADC FIFO controls, using regmap_field's - RX/TX FIFO addresses, with offsets stored directly, as these are only used to setup DMA and not actually accessed by the driver - card setup functions, as the newer codecs have a very different layout Patch 3 fixes some of the comments in the register definition section, so the separation of different functions is clearer. Patch 4 increases the maximum DMA burst size from 4 to 8. 4 is not a valid size on later SoCs. Patch 5 adds driver support for an optional reset control. Patches 6 through 11 add support for the A31's internal codec, one feature per patch. Hopefully this makes it easier to review. Some features, such as PHONE inputs/outputs, audio processing, headset jack detection and buttons, aren't supported yet. Patch 12 adds a device node for the codec to the A31 dtsi. Patch 13 enables the codec for the Hummingbird A31 board. Patch 14 enables the codec for the Sinlinx SinA31s board. Please let me know what you think.
