Here's a set of 2 patches against Linus' repo. Renesas Reduced Pin Count Interface (RPC-IF) allows a SPI flash or HyperFlash connected to the SoC to be accessed via the external address space read mode or the manual mode. The memory controller driver for RPC-IF registers either SPI or HyperFLash subdevice, depending on the contents of the device tree subnode; it also provides the abstract "back end" API that can be used by the "front end" SPI/MTD drivers to talk to the real hardware... Based on the original patch by Mason Yang . [1/2] dt-bindings: memory: document Renesas RPC-IF bindings [2/2] memory: add Renesas RPC-IF driver MBR, Sergei
