Merge tag 'omap-for-v3.8-rc2/fixes-signed-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren: The biggest change is a fix to deal with different power state on omap2 registers that causes issues trying to use common PM code. Also fix few incorrect registers, and an issue for omap1 USB, and few sparse fixes for issues that sneaked in with all the clean-up. * tag 'omap-for-v3.8-rc2/fixes-signed-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: am33xx-hwmod: Fix wrongly terminated am33xx_usbss_mpu_irqs array ARM: OMAP1: fix USB configuration use-after-release ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return values ARM: OMAP3: clock data: Add missing enable/disable for EMU clock ARM: OMAP4: PRM: Correct wrong instance usage for reading reset sources ARM: OMAP4: PRM: fix RSTTIME and RSTST offsets ARM: OMAP4: PRM: Correct reset source map ARM: OMAP: SRAM: resolve sparse warnings ARM: OMAP AM33xx: hwmod data: resolve sparse warnings ARM: OMAP: 32k counter: resolve sparse warnings Signed-off-by: Olof Johansson <olof@lixom.net>
