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

      ARM i.MX53: Fix UART pad configuration · f5786b8e
      Philipp Zabel 提交于
      The current default pad configuration for UART RX and TX pads sets a 360k
      pull-down and writes 1 to a reserved bit (1 << 0). It doesn't seem right to
      me that in idle state, the UART has to keep the signal high against a
      pull-down resistor.
      
      This patch instead sets a 100k pull-up, which incidentally corresponds to the
      register reset value for all but one (MX53_PAD_KEY_ROW0__UART4_RXD_MUX) pad,
      and removes the write to the reserved bit.
