Merge tag 'omap-for-v4.3/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omaps for v4.3-rc cycle:

- Two more patches to fix most of the MMC regressions with the
  PBIAS regulator changes. At least two MMC driver related issues
  still seems to remain for omap3 legacy booting and omap4 duovero.
  Note that the dts changes depend on a recent regulator fix, and
  are based on the regulator commit now in mainline kernel

- Enable autoidle for am43xx clocks to prevent clocks from staying
  always on

- Fix i2c5 pinctrl offsets for omap5-uevm

- Enable PCA953X as that's needed for HDMI to work on omap5

- Update phy supplies for beagle x15 beta board

- Use palmas-usb for on beagle x15 to start using the related
  driver that recently got merged

* tag 'omap-for-v4.3/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: dts: fix omap2+ address translation for pbias

  ARM: OMAP2+: AM43XX: Enable autoidle for clks in am43xx_init_late
  ARM: dts: am57xx-beagle-x15: Update Phy supplies
  regulator: pbias: program pbias register offset in pbias driver
  ARM: omap2plus_defconfig: Enable MUSB DMA support
  ARM: DRA752: Add ID detect for ES2.0
