regmap: Export regcache_sync_region()

2012-04-03T12:08:53Z

regcache_sync_region() isn't going to be useful to most drivers if we don't export it since otherwise they can't use it when built modular. Signed-off-by: Mark Brown

Pull avoidance patches from Paul Gortmaker: "Nearly every subsystem has some kind of header with a proto like: void foo(struct device *dev); and yet there is no reason for most of these guys to care about the sub fields within the device struct. This allows us to significantly reduce the scope of headers including headers. For this instance, a reduction of about 40% is achieved by replacing the include with the simple fact that the device is some kind of a struct. Unlike the much larger module.h cleanup, this one is simply two commits. One to fix the implicit users, and then one to delete the device.h includes from the linux/include/ dir wherever possible." * tag 'device-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: device.h: audit and cleanup users in main include dir device.h: cleanup users outside of linux/include (C files)

device.h: cleanup users outside of linux/include (C files)

2012-03-11T18:27:37Z

For files that are actively using linux/device.h, make sure that they call it out. This will allow us to clean up some of the implicit uses of linux/device.h within include/* without introducing build regressions. Yes, this was created by "cheating" -- i.e. the headers were cleaned up, and then the fallout was found and fixed, and then the two commits were reordered. This ensures we don't introduce build regressions into the git history. Signed-off-by: Paul Gortmaker

regmap: Allow drivers to sync only part of the register cache

2012-02-24T14:52:41Z

Provide a regcache_sync_region() operation which allows drivers to write only part of the cache back to the hardware. This is intended for use in cases like power domains or DSP memories where part of the device register map may be reset without fully resetting the device. Fully supporting these devices is likely to require additional work to make specific regions of the register map cache only while they are in reset, but this is enough for most devices.

regmap: Supply ranges to the sync operations

2012-02-24T14:52:40Z

In order to allow us to support partial sync operations add minimum and maximum register arguments to the sync operation and update the rbtree and lzo caches to use this new information. The LZO implementation is obviously not good, we could exit the iteration earlier, but there may be room for more wide reaching optimisation there. Signed-off-by: Mark Brown

regmap: Add tracepoints for cache only and cache bypass

Useful for figuring out where the hardware interaction went or came from. Signed-off-by: Mark Brown

regmap: Mark the cache as clean after a successful sync

2012-02-23T22:07:19Z

Previously the cache would never be marked clean, meaning syncs would never be suppressed which isn't the end of the world but could be inefficient. Signed-off-by: Mark Brown
