[PATCH 1/3] ASoC: add 88pm860x codec driver
by Haojian Zhuang 12 Aug '10

12 Aug '10

Add 88PM860x codec driver. 88PM860x codec supports two interfaces. And it also supports headset/mic/hook/short detection.

[PATCH 1/3] ASoC: add 88pm860x codec driver
by Haojian Zhuang 12 Aug '10

12 Aug '10

Add 88PM860x codec driver. 88PM860x codec supports two interfaces. And it also supports headset/mic/hook/short detection.

[PATCH 1/3] ASoC: add 88pm860x codec driver
by Haojian Zhuang 12 Aug '10

12 Aug '10

Add 88PM860x codec driver. 88PM860x codec supports two interfaces. And it also supports headset/mic/hook/short detection.

[PATCH 4/5] ASoC: add 88pm860x codec driver
by Haojian Zhuang 12 Aug '10

12 Aug '10

Add 88PM860x codec driver. 88PM860x codec supports two interfaces. And it also supports headset/mic/hook/short detection.
