Patches 12 and 13 introduce the sam9x60 qspi controller. sam9x60 qspi controller tested with sst26vf064b jedec,spi-nor flash. Backward compatibility test done on sama5d2 qspi controller and mx25l25635e jedec,spi-nor flash. The patches are generated on top of for-next branch. v3: - update smm value when different. - treat just regular spi transfers when introducing sam9x60 qspi IP. Mem transfers will be added together with dirmap support. - reorganize the code and change ops functions pointers to avoid code duplication. - rename aq->clk to aq->pclk to indicate that it's a peripheral clock. - drop unused and NOP transfer macros. - add Suggested-by tags, reword some commits. v2: - cache MR value, - drop iomem wrappers, - make "pclk" clock-name mandatory even for sama5d2, - rework clock handling, - reorder setting of register values in set_cfg() calls, - collect R-b tags.
