Mark Brown	5879f5710e	mfd: Release arizona DCVDD if we fail to resume the device ... Ensures we don't leak the enable we just did. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>	2012-07-09 00:39:06 +02:00
Mark Brown	59db96913c	mfd: Move arizona digital core supply management to the regulator API ... Rather than open coding the enable GPIO control in the MFD core use the API to push the management on to the regulator driver. The immediate advantage is slight for most systems but this will in future allow device configurations where an external regulator is used for DCVDD.

Mark Brown	3cc7298694	mfd: arizona: Core driver ... Several forthcoming Wolfson devices are based on a common platform known as Arizona allowing a great deal of reuse of driver code. This patch adds core support for these devices. In order to handle systems which do not use the generic clock API a simple wrapper for the 32kHz clock domain in the devices is provided. Once the generic clock API is widely available this code will be moved over to use that. For simplicity some WM5102 specific code is included in the core driver, the effort involved in splitting the device out isn't worth it.
