    ARM: dts: imx53: make pinctrl nodes board specific · 7ac0f700
    Shawn Guo authored
    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.
