Merge tag 'omap-for-v3.17/fixes-against-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "omap fixes against v3.17-rc2" from Tony Lindgren:

Fixes for omaps, mostly to revert NAND back to using software ECC
by default as that's what many boards expect. Also fixes for omap5
clocks, PM wake-up events, GPIO interrupt cells for dra7, and few
other minor fixes.

* tag 'omap-for-v3.17/fixes-against-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: dts: omap54xx-clocks: Fix the l3 and l4 clock rates
  ARM: OMAP2+: hwmod: Rearm wake-up interrupts for DT when MUSB is idled
  ARM: dts: Enable UART wake-up events for beagleboard
  ARM: dts: Remove twl6030 clk32g "regulator"
  ARM: OMAP2+: omap_device: remove warning that clk alias already exists
  ARM: OMAP: fix %d confusingly prefixed with 0x in format string
  ARM: dts: DRA7: fix interrupt-cells for GPIO
  mtd: nand: omap: Fix 1-bit Hamming code scheme, omap_calculate_ecc()
  ARM: dts: omap3430-sdp: Revert to using software ECC for NAND
  ARM: OMAP2+: GPMC: Support Software ECC scheme via DT
  mtd: nand: omap: Revert to using software ECC by default
