Merge branch 'for-v4.7/gpmc-mtd-common' of github.com:rogerq/linux into nand/next

Pull NAND/GPMC updates from Roger Quadros:
 "We do a couple of things in this series which result in cleaner device
  tree implementation, faster perfomance and multi-platform support. As
  an added bonus we get to use the GPMC_WAIT pins as GPI/Interrupts.

  - Establish a custom interface between NAND and GPMC driver. This is
    needed because all of the NAND registers sit in the GPMC register
    space.

  - Clean up device tree support so that omap-gpmc IP and the omap2 NAND
    driver can be used on non-OMAP platforms. e.g. Keystone.

  - Implement GPIOCHIP for the GPMC WAITPINS. SoCs can contain 2 to 4 of
    these and most of them would be unused otherwise. It also allows a
    cleaner implementation of NAND Ready pin status for the NAND driver.

  - Implement GPMC IRQ domain to proivde the 2 NAND events and GPMC
    WAITPIN edge interrupts.

  - Implement GPIOlib based NAND ready pin checking for OMAP NAND driver.
    On dra7-evm, Read speed increases from 13768 KiB/ to 17246 KiB/s.
    Write speed was unchanged at 7123 KiB/s."
