* mfd: ab8500-core chip version cut 2.0 supportMattias Wallin2011-01-14
| | | | | | | | | This patch adds support for chip version 2.0 or cut 2.0. One new interrupt latch register - latch 12 - is introduced.

* mfd: Flag WM831x /IRQ as a wake sourceMark Brown2011-01-14
| | | | | | | | | 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 <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* mfd: Support LP3974 RTCMyungJoo Ham2011-01-14
| | | | | | | | | | | | | | | | | | | | | | 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.

* mfd: Remove ARCH_U8500 dependency from AB8500Mark Brown2011-01-14
| | | | | | | | | | | While it is vanishingly unlikely that the device will be deployed on other architectures removing the dependency facilitates build testing when doing generic work on both the MFD core for the device and the subsystem drivers. There appears to be no actual code dependency. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.
