phy: rockchip-emmc: adapt binding to specifiy register offset
From: Heiko Stuebner <heiko@...> Date: Thu, 24 Mar 2016 22:22:15 +0100
Commit-Message
The emmc-phy occupies a contiguous set of 8 registers inside the general register files, so the reg property should specify this. Signed-off-by: Heiko Stuebner <heiko@...>
Patch-Comment
This is essential a counter argument for Shawn's move from reg to reg_offset in "phy: rockchip-emmc: fix compile issue on arm64 platform" [0]. With the move under the grf we now also are able to specify this stuff cleanly using already present mechanisms. Also meant to v4.6-rc before the binding solidifies.
