Merge tag 'gpio-omap-descriptors-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into soc/arm

This removes all usage of global GPIO numbers from
arch/arm/mach-omap[12].

The patches have been reviewed and tested by everyone
who showed interest which was one person that tested
on OSK1 and Nokia 770, and we smoked out the bugs and
also addressed all review comments.

Any remaining problems can certainly be fixed in-tree.

* tag 'gpio-omap-descriptors-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  ARM/musb: omap2: Remove global GPIO numbers from TUSB6010
  ARM: omap2: Rewrite WLAN quirk to use GPIO descriptors
  ARM: omap2: Get USB hub reset GPIO from descriptor
  ARM/gpio: Push OMAP2 quirk down into TWL4030 driver
  ARM: omap1: Exorcise the legacy GPIO header
  ARM: omap1: Make serial wakeup GPIOs use descriptors
  ARM: omap1: Fix up the Nokia 770 board device IRQs
  ARM/mmc: Convert old mmci-omap to GPIO descriptors
  Input: ads7846 - Convert to use software nodes
  ARM: omap1: Remove reliance on GPIO numbers from SX1
  ARM: omap1: Remove reliance on GPIO numbers from PalmTE
  ARM: omap1: Drop header on AMS Delta
  ARM/mfd/gpio: Fixup TPS65010 regression on OMAP1 OSK1
