Merge tag 'omap-for-v3.10/fixes-non-critical-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical
From Tony Lindgren <tony@atomide.com>:
Non critical omap fixes for v3.10 merge window. A big chunk
of these fixes are needed to support omap5 es2 version that includes
PM features while the earlier version es1 did not.
* tag 'omap-for-v3.10/fixes-non-critical-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: fix typo "CONFIG_BRIDGE_DVFS"
ARM: OMAP1: remove "config MACH_OMAP_HTCWIZARD"
ARM: OMAP: dpll: enable bypass clock only when attempting dpll bypass
ARM: OMAP2+: powerdomain: avoid testing whether an unsigned char is less than 0
ARM: OMAP2+: hwmod: Remove unused _HWMOD_WAKEUP_ENABLED flag
ARM: OMAP2+: am335x: Change the wdt1 func clk src to per_32k clk
ARM: OMAP2+: AM33xx: hwmod: Add missing sysc definition to wdt1 entry
Contains an update to 3.9-rc5
