	moderated list:ARM/Mediatek SoC support, open list,
	moderated list:ARM/Mediatek SoC support,
	open list:REMOTE PROCESSOR (REMOTEPROC) SUBSYSTEM

Add support for controlling and communicating with mt8183's system
control processor (SCP), using the remoteproc & rpmsg framework.
And also add a cros_ec driver for CrOS EC host command over rpmsg.

The overall structure of the series is:
* remoteproc/mtk_scp.c: Control the start / stop of SCP (Patch 2).
* remoteproc/mtk_scp_ipi.c: Communicates to SCP using inter-processor
  interrupt (IPI) and shared memory (Patch 2).
* rpmsg/mtk_rpmsg.c: Wrapper to wrap the IPI communication into a rpmsg
  device. Supports name service for SCP firmware to
  announce channels (Patch 3).
* add scp dts node to mt8183 platform (Patch 4).

Changes from v20:
 - Change all public API usage of (struct platform_device *) to (struct
   mtk_scp *).
 - Rename some variables and functions to be more specific.
 - Move docs to implementation, and improve docs.
 - Address review comments.

Changes from v19:
 - Fix an incorrect include in mtk_rpmsg.h (linux/device.h ->
   linux/platform_device.h)

Changes from v18:
 - Change the way shared memory is handled, and drop patch 3.

Changes from v17:
 - Fix mixture use of __iomem found by sparse.
 - Change the ipi handler to take a u32 instead of enum scp_ipi_id.
 - Mark mtk_rpmsg_{prepare,unprepare,stop} as static.

Changes from v16:
 - Change the desc_lock mutex to be a per-id lock.
 - Put the execution of handler inside the per-id lock, to prevent race
   between scp_ipi_unregister and handler being run.
 - Move the initialization of mutex to before scp_ipi_register.

Changes from v15:
 - Fix a bug on incorrect usage of wait_event_timeout return value.

Changes from v14:
 - Fix a typo on variable in DEBUG section.

Changes from v13:
 - Move include/linux/platform_data/mtk_scp.h to
   include/linux/remoteproc/mtk_scp.h.
 - Rename scp_get_reserve_* to scp_get_reserved_*.
 - Add lock for access of scp->ipi_desc.
 - Lock the whole ipi_send function.
 - Move more setting of cache size from SCP firmware to kernel driver,
   to prevent problem while loading firmware onto DRAM.
 - Minor fixes addressing comment.

Changes from v12:
 - Initialize cache before firmware load, to avoid problem while loading
   large firmware.
 - Disable watchdog before stopping SCP, to avoid extra warning message.
 - Fix new warnings by checkpatch.

Changes from v11:
 - Fixed a bug that mtk_rpmsg_endpoint is not properly cleaned up if
   rproc_boot fails.
 - Add missing documentation in comment.

Changes from v10:
 - Drop applied cros_ec_rpmsg patches.
 - Add clock reset before loading SCP firmware.
 - Fix some type mismatch warnings when printing debug messages.

Changes from v9:
 - Remove reserve-memory-vpu_share node.
 - Remove change to cros_ec_commands.h (That is already in
   https://lore.kernel.org/lkml/20190518063949.GY4319@dell/T/)

Changes from v8:
 - Rebased onto https://patchwork.kernel.org/cover/10962385/.
 - Drop merged cros_ec_rpmsg patch, and add scp dts node patch.
 - Add more reserved memory region.

Changes from v7:
 - Rebase onto https://lore.kernel.org/patchwork/patch/1059196/.
 - Fix clock enable/disable timing for SCP driver.
 - Add more SCP IPI ID.

Changes from v6:
 - Decouple mtk_rpmsg from mtk_scp.
 - Change data of EC response to be aligned to 4 bytes.

Changes from v5:
 - Add device tree binding document for cros_ec_rpmsg.
 - Better document in comments for cros_ec_rpmsg.
 - Remove dependency on CONFIG_ in binding tree document.

Changes from v4:
 - Merge patch 6 (Load ELF firmware) into patch 2, so the driver loads
   ELF firmware by default, and no longer accept plain binary.
 - rpmsg_device listed in device tree (as a child of the SCP node) would
   have it's device tree node mapped to the rpmsg_device, so the rpmsg
   driver can use the properties on device tree.

Changes from v3:
 - Make writing to SCP SRAM aligned.
 - Add a new patch (Patch 6) to load ELF instead of bin firmware.
 - Add host event support for EC driver.
 - Fix some bugs found in testing (missing spin_lock_init,
   rproc_subdev_unprepare to rproc_subdev_stop).
 - Fix some coding style issue found by checkpatch.pl.

Changes from v2:
 - Fold patch 3 into patch 2 in v2.
 - Move IPI id around to support cross-testing for old and new firmware.
 - Finish more TODO items.

Changes from v1:
 - Extract functions and rename variables in mtk_scp.c.
 - Do cleanup properly in mtk_rpmsg.c, which also removes the problem of
   short-lived work items.
 - Code format fix based on feedback for cros_ec_rpmsg.c.
 - Extract feature detection for SCP into separate patch (Patch 6).

Changes from v20 ... v6:
 - No change.

Changes from v5:
 - Remove dependency on CONFIG_RPMSG_MTK_SCP.

Changes from v4:
 - Add detail of more properties.
 - Document the usage of mtk,rpmsg-name in subnode from the new design.

Changes from v3:
 - No change.

Changes from v2:
 - No change. I realized that for this patch series, there's no need to
   add anything under the mt8183-scp node (neither the mt8183-rpmsg or
   the cros-ec-rpmsg) for them to work, since mt8183-rpmsg is added
   directly as a rproc_subdev by code, and cros-ec-rpmsg is dynamically
   created by SCP name service.

Changes from v1:
 - No change.

+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";
+	};

Sorry I somehow oversaw this. Next time please don't doubt to ping me.

Bjorn, do I understand correctly that you don't send emails to the list 
informing of the inclusion of a patch/series in your tree?

Anyway applied now to v5.9-next/dts64 :)

Thanks!

I just hit it as well... I wish the kernel was built after applying
patches... it would make the next a better place.

I just sent https://lore.kernel.org/patchwork/patch/1303034/ which
should fix this.

The build failure is because another patch for the mt8183-kukui.dtsi
(cd894e274b74 "arm64: dts: mt8183: Add krane-sku176 board") that was
merged after this patch is submitted to list is missing the
scp_mem_reserved field. Sorry for that.

I'll remove the patch now until this is fixed. Once again sorry for the trouble.
