These GPIOs are hadled via the System Management Controller. The first patch adds the core SMC support to the MFD subsystem. Patch 2 prepares the printf code for printing generic fourccs, as required by patch 4 and 7. Patch 3 adds the DT binding documentation for the rtkit backend. Patch 4 adds the rtkit backend for the SMC core. Patch 5 adds the device tree updates for the rtkit communication channel and gpio sub device to DT. Patch 6 adds the DT binding documentation for the gpio client. Patch 7 adds the gpio client. Patches mostly taken from the Asahi project and then modified due to review comments from the previous postings. I may have missed some comments as there's been quite a lot of discussion on previous postings.
