[PATCH 0/2] ARM: dtsi: r8a7745: iwg22m: Add eMMC support

[Fabrizio Castro]

This series adds eMMC support to r8a7745 SoC and iW-RainboW-G22M-SM SoM.

Testing has been made on top of Renesas's devel branch.

The patches contained in this series depend on the following patches:
[1/2] ARM: dts: iwg22m: Add iWave RZG1E SODIMM SOM - https://patchwork.kernel.org/patch/9901619/
[2/2] ARM: dts: iwg22d-sodimm: Add support for iWave G22D-SODIMM board - https://patchwork.kernel.org/patch/9901623/
dt-bindings: mmc: sh_mmcif: Document r8a7745 DT bindings - https://patchwork.kernel.org/patch/9902199/
