      Commit 5169df8b ("ARM: dts: i.MX53: add support for MCIMX53-START-R")
      missed to configure the IOMUX for the PMIC IRQ pin.
      
      Configure the PMIC IRQ pin so that the suspend/resume sequence behaves cleanly
      as expected.

      ARM: dts: imx6sx: fix the pad setting for uart CTS_B · 3bc4d037
      Fugang Duan authored
      The current pinfunc define all uart CTS_B IO port for DCE uart 'CTS_B'
      IP port. Since uart IP port 'CTS_B' is output, and it don't need to
      set 'SELECT_INPUT' bit.
