Merge tag 'gemini-dts' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt

Gemini DTS updates for v4.21:
- Fix the erroneous partition table on D-Link DIR-685
- Multiplex flash usage with other usage using pin control
  handling (merged to the MTD tree)
- Use the RedBoot partition parser on SQ201
- Add the USB blocks (DT bindings merged in the last merge
  window)
- Bump the debounce times a bit to avoid bouncing

* tag 'gemini-dts' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik:
  ARM: dts: Bump Gemini platforms to use 100ms debounce
  ARM: dts: Add the FOTG210 USB host to Gemini boards
  ARM: dts: Fix up SQ201 flash access
  ARM: dts: Enable Gemini flash access
  ARM: dts: Fix up the D-Link DIR-685 MTD partition info
