ASoC: WM8903: Fix platform data gpio_cfg confusion

2011-12-06T10:29:22Z

wm8903_platform_data.gpio_cfg[] was intended to be interpreted as follows: 0: Don't touch this GPIO's configuration register 1..7fff: Write that value to the GPIO's configuration register 8000: Write zero to the GPIO's configuration register other: Undefined (invalid) The rationale is that platform data is usually global data, and a value of zero means that the field wasn't explicitly set to anything (e.g. because the field was new to the pdata type, and existing users weren't update to initialize it) and hence the value zero should be ignored. 0x8000 is an explicit way to get 0 in the register. The code worked this way until commit 7cfe561 "ASoC: wm8903: Expose GPIOs through gpiolib", where the behaviour was changed due to my lack of awareness of the above rationale. This patch reverts to the intended behaviour, and updates all in-tree users to use the correct scheme. This also makes WM8903 consistent with other devices that use a similar scheme. WM8903_GPIO_NO_CONFIG is also renamed to WM8903_GPIO_CONFIG_ZERO so that its name accurately reflects its purpose.

ASoC: wm8903: Expose GPIOs through gpiolib

2011-01-21T18:15:13Z

Also, update platform_data GPIO handling to have an explicit "don't touch this pin" option. Add #defines for the GPIO pin functions. Signed-off-by: Stephen Warren Acked-by: Liam Girdwood Signed-off-by: Mark Brown

ASoC: Implement interrupt driven microphone detection for WM8903

2010-03-16T15:57:43Z

Support use of the WM8903 IRQ for reporting of microphone presence and short detection. Signed-off-by: Mark Brown Acked-by: Liam Girdwood

ASoC: Add WM8903 interrupt support

ASoC: Initial WM8903 microphone bias and short detection

2010-03-16T15:56:54Z

Provide support for WM8903 microphone presence and short detection using the GPIOs to route out a logic signal suitable for handling using snd_soc_jack_add_gpios() on the processor GPIOs. Signed-off-by: Mark Brown Acked-by: Liam Girdwood

ASoC: Add GPIO configuration support for WM8903

2010-03-16T15:56:34Z

Allow users to pass in a default configuration for the GPIOs of the WM8903 as platform data. This allows configuration of the pin muxing of the device. Signed-off-by: Mark Brown Acked-by: Liam Girdwood
