ASoC: wm8962: Let CODEC driver enable and disable its own MCLK

2014-07-31T19:51:26Z

snd_soc_open() will trigger pm_runtime resume() which will then enable the regulator and initialization. So we should make sure the MCLK is enabled before this resume(). Previously we let the machine driver get the clock and enable it in its probe(). However, considering about power saving, it'll be better to enable it when it's going to be used and disable it after using. So this patch just simply adds clk_get() and clk_enable() to WM8962 driver. Meanwhile, it marks clock pointer to NULL if no clock assigned to it so it will not break any current function.

ASoC: wm8962: Optimise power consumption for IN4 DC measurement usage

2012-01-24T21:19:45Z

When the hardware is configured with one or both of the IN4 inputs used for DC measurement (with no DC blocking capacitor connected) then we can improve power consumption slightly in idle modes by applying a register write sequence. Provide platform data to enable this, implemented using a regmap patch. Signed-off-by: Mark Brown

ASoC: Add support for WM8962 GPIO outputs

2010-10-02T21:23:04Z

The WM8962 features five GPIOs, add support for controlling their output state via gpiolib. Signed-off-by: Mark Brown Acked-by: Liam Girdwood

ASoC: Provide microphone bias configuration for WM8962

2010-09-30T16:36:13Z

Add the widget for MICBIAS power control and allow configuration of the microphone bias setup via the platform data for the WM8962. When microphone status signals are brought out to GPIO this should be sufficient to enable microphone detection. Signed-off-by: Mark Brown Acked-by: Liam Girdwood

ASoC: Initial WM8962 IRQ support

2010-09-29T07:32:36Z

Provide an initial hookup for interrupts on the WM8962. Currently we simply report error status via log messages if an IRQ is provided for the device. Signed-off-by: Mark Brown Acked-by: Liam Girdwood

ASoC: Add initial WM8962 CODEC driver

2010-08-05T12:38:57Z

The WM8962 is a low power, high performance stereo CODEC designed for portable digital audio applications. This initial driver release supports the key audio paths of the WM8962. Extended functionality, such as microphone detection, digital microphones and the advanced DSP signal enhancements provided by the device are not yet supported. Signed-off-by: Mark Brown
