Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

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"

+NXP i.MX System Controller Firmware (SCFW)
+--------------------------------------------------------------------
+
+The System Controller Firmware (SCFW) is a low-level system function
+which runs on a dedicated Cortex-M core to provide power, clock, and
+resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
+(QM, QP), and i.MX8QX (QXP, DX).
+
+The AP communicates with the SC using a multi-ported MU module found
+in the LSIO subsystem. The current definition of this MU module provides
+5 remote AP connections to the SC to support up to 5 execution environments
+(TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
+with the LSIO DSC IP bus. The SC firmware will communicate with this MU
+using the MSI bus.
+
+System Controller Device Node:
+============================================================
+
+The scu node with the following properties shall be under the /firmware/ node.
+
+Required properties:
+-------------------
+- compatible:	should be "fsl,imx-scu".
+- mbox-names:	should include "tx0", "tx1", "tx2", "tx3",
+			       "rx0", "rx1", "rx2", "rx3".
+- mboxes:	List of phandle of 4 MU channels for tx and 4 MU channels
+		for rx. All 8 MU channels must be in the same MU instance.
+		Cross instances are not allowed. The MU instance can only
+		be one of LSIO MU0~M4 for imx8qxp and imx8qm. Users need
+		to make sure use the one which is not conflict with other
+		execution environments. e.g. ATF.
+		Note:
+		Channel 0 must be "tx0" or "rx0".
+		Channel 1 must be "tx1" or "rx1".
+		Channel 2 must be "tx2" or "rx2".
+		Channel 3 must be "tx3" or "rx3".
+		e.g.
+		mboxes = <&lsio_mu1 0 0
+			  &lsio_mu1 0 1
+			  &lsio_mu1 0 2
+			  &lsio_mu1 0 3
+			  &lsio_mu1 1 0

+Device Tree Bindings for the Xilinx Zynq MPSoC Firmware Interface
+-----------------------------------------------------------------
+
+The zynqmp-firmware node describes the interface to platform firmware.
+ZynqMP has an interface to communicate with secure firmware. Firmware
+driver provides an interface to firmware APIs. Interface APIs can be
+used by any driver to communicate to PMUFW(Platform Management Unit).
+These requests include clock management, pin control, device control,
+power management service, FPGA service and other platform management
+services.
+
+Required properties:
+ - compatible:	Must contain:	"xlnx,zynqmp-firmware"
+ - method:	The method of calling the PM-API firmware layer.
+		Permitted values are:
+		  - "smc" : SMC #0, following the SMCCC
+		  - "hvc" : HVC #0, following the SMCCC

+Device Tree Clock bindings for the Zynq Ultrascale+ MPSoC controlled using
+Zynq MPSoC firmware interface
+--------------------------------------------------------------------------
+The clock controller is a h/w block of Zynq Ultrascale+ MPSoC clock
+tree. It reads required input clock frequencies from the devicetree and acts
+as clock provider for all clock consumers of PS clocks.
+
+See clock_bindings.txt for more information on the generic clock bindings.
+
+Required properties:
+ - #clock-cells:	Must be 1
+ - compatible:		Must contain:	"xlnx,zynqmp-clk"
+ - clocks:		List of clock specifiers which are external input
+			clocks to the given clock controller. Please refer
+			the next section to find the input clocks for a
+			given controller.
+ - clock-names:		List of clock names which are exteral input clocks
+			to the given clock controller. Please refer to the
+			clock bindings for more details.
+
+Input clocks for zynqmp Ultrascale+ clock controller:
+
+The Zynq UltraScale+ MPSoC has one primary and four alternative reference clock
+inputs. These required clock inputs are:
+ - pss_ref_clk (PS reference clock)
+ - video_clk (reference clock for video system )
+ - pss_alt_ref_clk (alternative PS reference clock)
+ - aux_ref_clk
+ - gt_crx_ref_clk (transceiver reference clock)
+
+The following strings are optional parameters to the 'clock-names' property in
+order to provide an optional (E)MIO clock source:
+ - swdt0_ext_clk
+ - swdt1_ext_clk
+ - gem0_emio_clk
+ - gem1_emio_clk
+ - gem2_emio_clk
+ - gem3_emio_clk
+ - mio_clk_XX		# with XX = 00..77
+ - mio_clk_50_or_51	#for the mux clock to gem tsu from 50 or 51
+
+
+Output clocks are registered based on clock information received
+from firmware. Output clocks indexes are mentioned in
+include/dt-bindings/clock/xlnx,zynqmp-clk.h.

+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>;
+};
