Pull ARM SoC driver updates from Olof Johansson: "Various driver updates for platforms: - A larger set of work on Tegra 2/3 around memory controller and regulator features, some fuse cleanups, etc.. - MMP platform drivers, in particular for USB PHY, and other smaller additions. - Samsung Exynos 5422 driver for DMC (dynamic memory configuration), and ASV (adaptive voltage), allowing the platform to run at more optimal operating points. - Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas - Clock/reset control driver for TI/OMAP - Meson-A1 reset controller support - Qualcomm sdm845 and sda845 SoC IDs for socinfo" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (150 commits) firmware: arm_scmi: Fix doorbell ring logic for !CONFIG_64BIT soc: fsl: add RCPM driver dt-bindings: fsl: rcpm: Add 'little-endian' and update Chassis definition memory: tegra: Consolidate registers definition into common header memory: tegra: Ensure timing control debug features are disabled memory: tegra: Introduce Tegra30 EMC driver memory: tegra: Do not handle error from wait_for_completion_timeout() memory: tegra: Increase handshake timeout on Tegra20 memory: tegra: Print a brief info message about EMC timings memory: tegra: Pre-configure debug register on Tegra20 memory: tegra: Include io.h instead of iopoll.h memory: tegra: Adapt for Tegra20 clock driver changes memory: tegra: Don't set EMC rate to maximum on probe for Tegra20 memory: tegra: Add gr2d and gr3d to DRM IOMMU group memory: tegra: Set DMA mask based on supported address bits soc: at91: Add Atmel SFR SN (Serial Number) support memory: atmel-ebi: switch to SPDX license identifiers memory: atmel-ebi: move NUM_CS definition inside EBI driver soc: mediatek: Refactor bus protection control soc: mediatek: Refactor sram control ...

+OMAP PRM instance bindings
+
+Power and Reset Manager is an IP block on OMAP family of devices which
+handle the power domains and their current state, and provide reset
+handling for the domains and/or separate IP blocks under the power domain
+hierarchy.
+
+Required properties:
+- compatible: Must contain one of the following:
+ "ti,am3-prm-inst"
+ "ti,am4-prm-inst"
+ "ti,omap4-prm-inst"
+ "ti,omap5-prm-inst"
+ "ti,dra7-prm-inst"
+ and additionally must contain:
+ "ti,omap-prm-inst"
+- reg: Contains PRM instance register address range
+ (base address and length)
+
+Optional properties:
+- #reset-cells: Should be 1 if the PRM instance in question supports resets.
+
+Example:
+
+prm_dsp2: prm@1b00 {
+ compatible = "ti,dra7-prm-inst", "ti,omap-prm-inst";
+ reg = <0x1b00 0x40>;
+ #reset-cells = <1>;
+};
