Merge tag 'omap-for-v4.10/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Pull "omap fixes for v4.10-rc cycle" from Tony Lindgren:

Fist set of fixes for omaps for v4.10-rc cycle, mostly
to deal with various regressions noticed during the merge
window and to fix various device tree configurations for
boards. Also included is removal of mach-omap2/gpio.c that
is now dead code with device tree based booting that should
be OK for the early -rc cycle:

- A series of fixes to add empty chosen node to fix regressions
  caused for bootloaders that don't create chosen node as the
  decompressor needs the chosen node to merge command line and
  ATAGs into it

- Fix missing logicpd-som-lv-37xx-devkit.dtb entry in Makefile

- Fix regression for am437x timers

- Fix wrong strcat for non-NULL terminated string

- A series of changes to fix tps65217 interrupts to not use
  defines as we don't do that for interrupts

- Two patches to fix USB VBUS detection on am57xx-idk and force it
  to peripheral mode until dwc3 role detection is working

- Add missing dra72-evm-tps65917 missing voltage supplies
  accidentally left out of an earlier patch

- Fix n900 eMMC detection when booted on qemu

- Remove unwanted pr_err on failed memory allocation for
  prm_common.c

- Remove legacy mach-omap2/gpio.c that now is dead code
  since we boot mach-omap2 in device tree only mode

- Fix am572x-idk pcie1 by adding the missing gpio reset pin
