Subject: [PATCH v23 00/18] ARM Primecell PL35x support

Hello,

I am taking over Naga's series, here are the major changes:
* Cleaning of the SMC bus binding file (and yaml conversion)
* Superficial cleaning and great simplification of the SMC bus driver
* Addition of a yaml file describing the NAND controller
* Full rework of the NAND controller driver. JFFS2 and UBIFS not tested
  yet, only bare test tools have been used to proove basic correctness
  of the helpers.
* Addition of a couple of MAINTAINERS entries.

A Github branch named pl353 is available on my repository:
https://github.com/miquelraynal/linux/

Thanks,
Miquèl

Changes in v23:
- Collected Naga Acked-by's.
- Used const instead of single enum entries in the bindings.
- Dropped the address-cells/size-cells superfluous definitions out of
  the NAND controller binding.
- Enhanced the SMC reg property description to mention that the various
  CS are described in the ranges property.
- Fixed the SMC child nodes regex to match Rob's requirements.

Changes in v22:
- Misc typo fixes.
- Light rewording of a few commit titles.
- Not forgetting to Cc: Rob and Krzysztof this time...

Changes in v21:
- Added Rob's Acked-by/Reviewed-by tags.
- Addressed all comments from Rob and Michael about the bindings.
- Tested both JFFS2 and UBIFS with simple file I/O.
