Hi all:
This series adds ASoC support for the Loongson-2K0300 SoC and its
associated development boards, including the CTCISZ Forever Pi and the
ATK-DL2K0300B.
Key changes:
- Extend DT bindings to support ls2k0300-i2s and new audio card
compatibles.
- Refactor the platform I2S driver to handle SoC differences via per-device
configuration (rev_id, optional APB DMA config, reset sequence).
- Refactor the audio machine driver to support board-specific DAI formats,
GPIO-based headphone detection/mute, speaker enable, and DAPM routing.
- Add jack detection and automatic switching between headphones and
speakers for the DL2K0300B board.
The patchset also cleans up the existing audio card binding by
referencing the common sound-card properties, and adds new compatibles
for the Loongson-2K0300 variants with proper DAI format handling.
All changes have been tested on Loongson-2K2000 (PCI), Loongson-2K0300
Forever Pi and Loongson-2K0300 DL2K0300B boards.
Thanks.
Binbin
