| Subject | [alsa-devel] [PATCH v5 0/9] ASoC: Mediatek: Add support for MT2701 SOC |
| Message-ID | <rKWHo-3Cb-11@gated-at.bofh.it> |
This patch adds basic support for Mediatek AFE for MT2701 SoC.
The patch is based on broonie tree "for-next" branch.
Change since v4:
* remove SND_SOC_MEDIATEK config prompt
* fix config prompt to meaningful one for SND_SOC_MT2701_CS42448
* remove some unnecessary random space change
Change since v3:
* fix comments style.
Change since v2:
* fix comments style.
* replace EXPORT_SYMBOL with EXPORT_SYMBOL_GPL
* reduce debug message
* move mutex lock for irq-allocated to AFE struct
* remove func mtk_simple_isr and call snd_pcm_period_elapsed directly
* mt2701 driver probe will fail if clock initial error
* fix dapm on/off switch control naming
Change since v1:
implement common private structure, fe dai and platform driver.
let mt8173 and mt2701 use the common structure.
Garlic Tseng (9):
ASoC: mediatek: Refine mt8173 driver and change config option
ASoC: mediatek: implement mediatek common structure
ASoC: mediatek: let mt8173 use mediatek common structure
ASoC: mediatek: add documents for mt2701
ASoC: mediatek: add structure define and clock control for 2701
ASoC: mediatek: add mt2701 platform driver implementation.
ASoC: bt-sco: extend rate and add a general compatible string
ASoC: mediatek: add BT implementation
ASoC: mediatek: Add mt2701-cs42448 driver and config option.
