Pull remoteproc updates from Bjorn Andersson: "This adds support for the Mediatek MT8183 SCP, modem remoteproc on Qualcomm SC7180 platform, audio and sensor remoteprocs on Qualcomm MSM8998 and audio, compute, modem and sensor remoteprocs on Qualcomm SM8150. It adds votes for necessary power-domains for all Qualcomm TrustZone based remoteproc instances are held, fixes a bug related to remoteproc drivers registering before the core has been initialized and does clean up the Qualcomm modem remoteproc driver" * tag 'rproc-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (21 commits) remoteproc: qcom: q6v5-mss: Improve readability of reset_assert remoteproc: qcom: q6v5-mss: Use regmap_read_poll_timeout remoteproc: qcom: q6v5-mss: Rename boot status timeout remoteproc: qcom: q6v5-mss: Improve readability across clk handling remoteproc: use struct_size() helper remoteproc: Initialize rproc_class before use rpmsg: add rpmsg support for mt8183 SCP. remoteproc/mediatek: add SCP support for mt8183 dt-bindings: Add a binding for Mediatek SCP remoteproc: mss: q6v5-mss: Add modem support on SC7180 dt-bindings: remoteproc: qcom: Add Q6V5 Modem PIL binding for SC7180 remoteproc: qcom: pas: Add MSM8998 ADSP and SLPI support dt-bindings: remoteproc: qcom: Add ADSP and SLPI support for MSM8998 SoC remoteproc: q6v5-mss: Remove mem clk from the active pool remoteproc: qcom: Remove unneeded semicolon remoteproc: qcom: pas: Add auto_boot flag remoteproc: qcom: pas: Add SM8150 ADSP, CDSP, Modem and SLPI support dt-bindings: remoteproc: qcom: SM8150 Add ADSP, CDSP, MPSS and SLPI support remoteproc: qcom: pas: Vote for active/proxy power domains dt-bindings: remoteproc: qcom: Add power-domain bindings for Q6V5 PAS ...

+Mediatek SCP Bindings
+----------------------------------------
+
+This binding provides support for ARM Cortex M4 Co-processor found on some
+Mediatek SoCs.
+
+Required properties:
+- compatible Should be "mediatek,mt8183-scp"
+- reg Should contain the address ranges for the two memory
+ regions, SRAM and CFG.
+- reg-names Contains the corresponding names for the two memory
+ regions. These should be named "sram" & "cfg".
+- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
+- clock-names Contains the corresponding name for the clock. This
+ should be named "main".
+
+Subnodes
+--------
+
+Subnodes of the SCP represent rpmsg devices. The names of the devices are not
+important. The properties of these nodes are defined by the individual bindings
+for the rpmsg devices - but must contain the following property:
+
+- mtk,rpmsg-name Contains the name for the rpmsg device. Used to match
+ the subnode to rpmsg device announced by SCP.
+
+Example:
+
+ scp: scp@10500000 {
+ compatible = "mediatek,mt8183-scp";
+ reg = <0 0x10500000 0 0x80000>,
+ <0 0x105c0000 0 0x5000>;
+ reg-names = "sram", "cfg";
+ clocks = <&infracfg CLK_INFRA_SCPSYS>;
+ clock-names = "main";
+ };
