Merge tag 'omap-for-v3.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

From Tony Lindgren:
Omap SoC changes. Mostly improves am33xx support, and adds
minimal support for am43x SoCs.

* tag 'omap-for-v3.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: AM43x: SRAM base and size
  ARM: OMAP2+: AM43x: GP or HS ?
  ARM: OMAP2+: AM43x: early init
  ARM: OMAP2+: AM43x: static mapping
  ARM: OMAP2+: AM437x: SoC revision detection
  ARM: OMAP2+: AM43x: soc_is support
  ARM: OMAP2+: AM43x: kbuild
  ARM: OMAP2+: AM43x: Kconfig
  ARM: OMAP2+: separate out OMAP4 restart
  ARM: AM33XX: clk: Add clock node for EHRPWM TBCLK
  ARM: OMAP3: clock data: get rid of unused USB host clock aliases and dummies
  ARM: OMAP2+: AM33xx: Add missing reset status info to GFX hwmod
  + Linux 3.10-rc5
