ARM: dts: imx: share pad macro names between imx6q and imx6dl
The imx6q and imx6dl are two pin-to-pin compatible SoCs. The same board design can work with either chip plugged into the socket, e.g. sabresd and sabreauto boards. We currently define pin groups in imx6q.dtsi and imx6dl.dtsi respectively because the pad macro names are different between two chips. This brings a maintenance burden on having the same label point to the same pin group defined in two places. The patch replaces prefix MX6Q_ and MX6DL_ with MX6QDL_ for both SoCs pad macro names. Then the pin groups becomes completely common between imx6q and imx6dl and can just be moved into imx6qdl.dtsi, so that the long term maintenance of imx6q/dt pin settings becomes easier. Unfortunately, the change brings some dramatic diff stat, but it's all about DTS file, and the ultimate net diff stat is good. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
