mfd: Don't suspend WM8994 if the CODEC is not suspended

2011-03-02T09:57:50Z

ASoC supports keeping the audio subsysetm active over suspend in order to support use cases such as audio passthrough from a cellular modem with the main CPU suspended. Ensure that we don't power down the CODEC when this is happening by checking to see if VMID is up and skipping suspend and resume when it is. If the CODEC has suspended then it'll turn VMID off before the core suspend() gets called. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Fix NULL pointer due to non-initialized ucb1x00-ts absinfo

2011-03-02T09:57:49Z

Call input_set_abs_params instead of manually setting absbit only.

mfd: Flag WM831x /IRQ as a wake source

2011-01-14T11:38:17Z

The WM831x can generate wake events, some unconditionally, so flag the primary IRQ as a wake source in order to help the CPU treat the /IRQ signal appropriately. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Convert WM831x away from legacy I2C PM operations

2011-01-14T11:38:17Z

Since the legacy bus PM operations are deprecated move the suspend method over to dev_pm_ops. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Support LP3974 RTC

2011-01-14T11:38:16Z

The first releases of LP3974 have a large delay in RTC registers, which requires 2 seconds of delay after writing to a rtc register (recommended by National Semiconductor's engineers) before reading it. If "rtc_delay" field of the platform data is true, the rtc driver assumes that such delays are required. Although we have not seen LP3974s without requiring such delays, we assume that such LP3974s will be released soon (or they have done so already) and they are supported by "lp3974" without setting "rtc_delay" at the platform data. This patch adds delays with msleep when writing values to RTC registers if the platform data has rtc_delay set.
