Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late changes from Olof Johansson: "We were expecting to sit on this branch through most of the merge window since the contents was merged into our tree late, but we ended up sitting on all of our contents so it can go in with the rest. The contents here is: - a large branch of cleanups of the CM/PRM blocks on OMAP. - a couple of patches plumbing up CM/PRM on OMAP5 and DRA7. - a branch with DT updates for Freescale i.MX. including some shuffling from .dts to .dtsi (include) files that causes a little churn" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (78 commits) ARM: OMAP2+: Fix booting with configs that don't have MFD_SYSCON ARM: OMAP4+: control: add support for initializing control module via DT ARM: dts: dra7: add minimal l4 bus layout with control module support ARM: dts: omap5: add minimal l4 bus layout with control module support ARM: OMAP4+: control: remove support for legacy pad read/write ARM: OMAP4: display: convert display to use syscon for dsi muxing ARM: dts: omap4: add minimal l4 bus layout with control module support ARM: dts: am4372: add minimal l4 bus layout with control module support ARM: dts: am43xx-epos-evm: fix pinmux node layout ARM: dts: am33xx: add minimal l4 bus layout with control module support ARM: dts: omap3: add minimal l4 bus layout with control module support ARM: dts: omap24xx: add minimal l4 bus layout with control module support ARM: OMAP2+: control: add syscon support for register accesses ARM: OMAP2+: id: cache omap_type value ARM: OMAP2+: control: remove API for getting control module base address ARM: OMAP2+: clock: add low-level support for regmap ARM: OMAP4+: PRM: get rid of cpu_is_omap44xx calls from interrupt init ARM: OMAP4+: PRM: setup prm_features from the PRM init time flags ARM: OMAP2+: CM: move SoC specific init calls within a generic API ARM: OMAP4+: PRM: determine prm_device_inst based on DT compatibility ...

+OMAP Control Module bindings
+
+Control Module contains miscellaneous features under it based on SoC type.
+Pincontrol is one common feature, and it has a specialized support
+described in [1]. Typically some clock nodes are also under control module.
+Syscon is used to share register level access to drivers external to
+control module driver itself.
+
+See [2] for documentation about clock/clockdomain nodes.
