[cip-dev] [PATCH 4.4.y-cip 00/10] Add SDHI/eMMC/USB2.0 support

[Biju Das]

This patch series add SDHI/eMMC/USB2.0 support for iWave iwg20d
platform based on RZ/G1N.

This patch series is based on linux-4.4.y-cip and all the patches
in this series are cherry-picked from linux rc tree.

[cip-dev] [PATCH 4.4.y-cip 08/10] dt-bindings: PCI: rcar: Add device tree support for r8a7744

[Biju Das]

commit 6adb734bb9c72c0fdcb1868edcc5fde3b6333d11 upstream.

Add internal PCI bridge support for r8a7744 SoC. The Renesas RZ/G1N
(R8A7744) internal PCI bridge is identical to the R-Car Gen2 family.

This doesn't change the driver, so it does nothing by itself.  But it does
mean that checkpatch won't complain about a future patch that adds
"renesas,pci-r8a7744" to a DT, which helps ensure that shipped DTs use
documented compatibility strings.
