Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that boards that share the same pinctrl setting do not have to define it time and time again in <board>.dts. However, along with the devices and use cases being added continuously, the pinctrl setting nodes under iomuxc becomes more than expected. This bloats device tree blob for particular board unnecessarily since only a small subset of those pinctrl setting nodes will be used by the board. It impacts not only the DTB file size but also the run-time device tree lookup efficiency. The patch moves all the pinctrl data into individual boards as needed. With the changes, the pinctrl setting nodes becomes local to particular board, and it makes no sense to continue numbering the setting for given peripheral. Thus, all the pinctrl phandler name gets updated to have only peripheral name in there. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Fugang Duan <B38611@freescale.com>
