Merge tag 'pm' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
power management changes for omap and imx A significant part of the changes for these two platforms went into power management, so they are split out into a separate branch. * tag 'pm' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (65 commits) ARM: imx6: remove __CPUINIT annotation from v7_invalidate_l1 ARM: imx6: fix v7_invalidate_l1 by adding I-Cache invalidation ARM: imx6q: resume PL310 only when CACHE_L2X0 defined ARM: imx6q: build pm code only when CONFIG_PM selected ARM: mx5: use generic irq chip pm interface for pm functions on ARM: omap: pass minimal SoC/board data for UART from dt arm/dts: Add minimal device tree support for omap2420 and omap2430 omap-serial: Add minimal device tree support omap-serial: Use default clock speed (48Mhz) if not specified omap-serial: Get rid of all pdev->id usage ARM: OMAP2+: hwmod: Add a new flag to handle hwmods left enabled at init ARM: OMAP4: PRM: use PRCM interrupt handler ARM: OMAP3: pm: use prcm chain handler ARM: OMAP: hwmod: add support for selecting mpu_irq for each wakeup pad ARM: OMAP2+: mux: add support for PAD wakeup interrupts ARM: OMAP: PRCM: add suspend prepare / finish support ARM: OMAP: PRCM: add support for chain interrupt handler ARM: OMAP3/4: PRM: add functions to read pending IRQs, PRM barrier ARM: OMAP2+: hwmod: Add API to enable IO ring wakeup ARM: OMAP2+: mux: add wakeup-capable hwmod mux entries to dynamic list ...

+OMAP UART controller
+
+Required properties:
+- compatible : should be "ti,omap2-uart" for OMAP2 controllers
+- compatible : should be "ti,omap3-uart" for OMAP3 controllers
+- compatible : should be "ti,omap4-uart" for OMAP4 controllers
+- ti,hwmods : Must be "uart<n>", n being the instance number (1-based)
+
+Optional properties:
+- clock-frequency : frequency of the clock input to the UART
