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 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.
