Pull ARM SoC driver updates from Arnd Bergmann: "The most noteworthy SoC driver changes this time include: - The TEE subsystem gains an in-kernel interface to access the TEE from device drivers. - The reset controller subsystem gains a driver for the Qualcomm Snapdragon 845 Power Domain Controller. - The Xilinx Zynq platform now has a firmware interface for its platform management unit. This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller. Additional cleanups and bugfixes in SoC specific drivers include the Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (129 commits) firmware: tegra: bpmp: Implement suspend/resume support drivers: clk: Add ZynqMP clock driver dt-bindings: clock: Add bindings for ZynqMP clock driver firmware: xilinx: Add zynqmp IOCTL API for device control Documentation: xilinx: Add documentation for eemi APIs MAINTAINERS: imx: include drivers/firmware/imx path firmware: imx: add misc svc support firmware: imx: add SCU firmware driver support reset: Fix potential use-after-free in __of_reset_control_get() dt-bindings: arm: fsl: add scu binding doc soc: fsl: qbman: add interrupt coalesce changing APIs soc: fsl: bman_portals: defer probe after bman's probe soc: fsl: qbman: Use last response to determine valid bit soc: fsl: qbman: Add 64 bit DMA addressing requirement to QBMan soc: fsl: qbman: replace CPU 0 with any online CPU in hotplug handlers soc: fsl: qbman: Check if CPU is offline when initializing portals reset: qcom: PDC Global (Power Domain Controller) reset controller dt-bindings: reset: Add PDC Global binding for SDM845 SoCs reset: Grammar s/more then once/more than once/ bus: ti-sysc: Just use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS ...

+Amlogic Canvas
+================================
+
+A canvas is a collection of metadata that describes a pixel buffer.
+Those metadata include: width, height, phyaddr, wrapping, block mode
+and endianness.
+
+Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
+rather than use the phy addresses directly. For instance, this is the case for
+the video decoders and the display.
+
+Amlogic SoCs have 256 canvas.

+Device Tree Bindings:

+Video Lookup Table
+--------------------------
+
+Required properties:
+- compatible: "amlogic,canvas"
+- reg: Base physical address and size of the canvas registers.
+
+Example:
+
+canvas: video-lut@48 {
+ compatible = "amlogic,canvas";
+ reg = <0x0 0x48 0x0 0x14>;
+};
