Pull pin control updates from Linus Walleij:
 "Here is the bulk of pin control changes for the v4.2 series: Quite a
  lot of new SoC subdrivers and two new main drivers this time, apart
  from that business as usual.

  Details:

  Core functionality:
   - Enable exclusive pin ownership: it is possible to flag a pin
     controller so that GPIO and other functions cannot use a single pin
     simultaneously.

  New drivers:
   - NXP LPC18xx System Control Unit pin controller
   - Imagination Pistachio SoC pin controller

  New subdrivers:
   - Freescale i.MX7d SoC
   - Intel Sunrisepoint-H PCH
   - Renesas PFC R8A7793
   - Renesas PFC R8A7794
   - Mediatek MT6397, MT8127
   - SiRF Atlas 7
   - Allwinner A33
   - Qualcomm MSM8660
   - Marvell Armada 395
   - Rockchip RK3368

  Cleanups:
   - A big cleanup of the Marvell MVEBU driver rectifying it to
     correspond to reality
   - Drop platform device probing from the SH PFC driver, we are now a
     DT only shop for SuperH
   - Drop obsolte multi-platform check for SH PFC
   - Various janitorial: constification, grammar etc

  Improvements:
   - The AT91 GPIO portions now supports the set_multiple() feature
   - Split out SPI pins on the Xilinx Zynq
   - Support DTs without specific function nodes in the i.MX driver"
