Merge branch 'component-for-driver' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into driver-core-next
Russell writes: These updates fix one bug in the component helper where the matched components are not properly cleaned up when the master fails to bind. I'll provide a version of this for stable trees if it's deemed that we need to backport it. The second patch causes the component helper to ignore duplicate matches when adding components - this is something that was originally needed for imx-drm, but since that has now been updated, we no longer need to skip over a component which has already been matched. The final patch starts the process of updating the component helper API to achieve two goals: to allow the API to be more efficient when deferred probing occurs, and to allow for future improvements to the component helper without having a major impact on the users. This represents groundwork for some other changes; once this has been merged, I will then send two further pull requests (one for the staging tree, and one for the DRM tree) to update the drivers to the new API. This will result in these three commits being shared with those trees.

+ * aspects:
+ * - it supports only one slave device, and thus drop the address field
+ * - it adds a parity bit every 8bits of data
+ * - only one read access is required to read a byte (instead of a write
+ * followed by a read access in standard SMBus protocol)
+ * - there's no Ack bit after each byte transfer
+ *
+ * This means this bus cannot be used to interface with standard SMBus
+ * devices (the only known device to support this interface is the AXP221
+ * PMIC).

help
IBM s/390 and zSeries machines running under z/VM 5.1 or later
provide a virtual watchdog timer to their guest that cause a
user define Control Program command to be executed after a
timeout.
+ LPAR provides a very similar interface. This driver handles
+ both.
To compile this driver as a module, choose M here. The module
will be called vmwatchdog.
