Merge tag 'omap-devel-prcm-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/pm
Updates for PRCM (Power, Reset, Clock Management). Note that this depends on omap-devel-hwmod-for-v3.5. By Kevin Hilman (3) and others via Paul Walmsley (2) and Tony Lindgren (1) * tag 'omap-devel-prcm-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: arm: omap3: clockdomain data: Remove superfluous commas from gfx_sgx_3xxx_wkdeps[] ARM: OMAP2+: powerdomain: Get rid off duplicate pwrdm_clkdm_state_switch() API ARM: OMAP3: clock data: add clockdomain for HDQ functional clock ARM: OMAP3+: dpll: Configure autoidle mode only if it's supported ARM: OMAP2+: dmtimer: cleanup iclk usage ARM: OMAP4+: Add prm and cm base init function. ARM: OMAP2/3: Add idle_st bits for ST_32KSYNC timer to prcm-common header ARM: OMAP3: Fix CM register bit masks ARM: OMAP: clock: convert AM3517/3505 detection/flags to AM35xx ARM: OMAP3: clock data: treat all AM35x devices the same ARM: OMAP3: clock data: replace 3503/3517 flag with AM35x flag for UART4
