The mediatek remoteproc driver currently only allows bringing up a 
single core SCP, e.g. MT8183. It also only bringing up the 1st 
core in SoCs with a dual-core SCP, e.g. MT8195. This series support 
to bring-up the 2nd core of the dual-core SCP.

v12 -> v13:
1. replace subdevice with new mediatek scp operations in patchset 7 
2. add review tag to patchset 3
3. modify mediatek,scp phandle name of video-codec@18000000 at patchset 11

v11 -> v12:
1. add scp_add_single/multi_core() to patchset 6
2. remove unused comment in patchset 6
3. rename list name from mtk_scp_cluster to mtk_scp_list
4. rewrite the multi-core probe flow 
5. disable rproc->autoboot and boot rproc by request_firmware_nowait at patchset 7 
6. remove patchset 7 review tag  

v10 -> v11:
1. rewrite patchset 5 to probe single-core SCP with the cluster list
2. Also in patchset 5, move the pointer of mtk_scp object from the
   platform data property to the driver data property 
3. move the appearance of mtk_scp cluster property to patcheset 7

v9 -> v10:
1. move the global mtk_scp list into the platform device driver data structure
2. remove an unnecessary if() condition

v8 -> v9:
1. initialize l1tcm_size/l1tcm_phys at patchset 05/11 
2. rewrite patchset 06/11 to unify the flow and remove hacks

v7 -> v8:
1. update the node name of mt8192 asurada SCP rpmsg subnode
2. squash register definitions into driver patches
3. initialize local variables on the declaration at patch v8 06/11 

v6 -> v7:
1. merge the mtk_scp_cluster struct into the mtk_scp structure
   at the "Probe multi-core SCP" patch

v5 -> v6:
1. move the mtk_scp_of_regs structure from mtk_common.h to mtk_scp.c
2. rename the SCP core 0 label from 'scp' to 'scp_c0'

v4 -> v5:
1. move resource release actions to the platform driver remove operation 
2. fix dual-core watchdog handling

v3 -> v4:
1. change the representation of dual-core SCP in dts file and update SCP yaml
2. rewrite SCP driver to reflect the change of dts node
3. drop 'remove redundant call of rproc_boot for SCP' in v3 for further investigation

v2 -> v3:
1. change the representation of dual-core SCP in dts file and update SCP yaml
2. rewrite SCP driver to reflect the change of dts node
3. add SCP core 1 node to mt8195.dtsi
4. remove redundant call of rproc_boot for SCP
5. refine IPI error message

v1 -> v2:
1. update dt-binding property description
2. remove kconfig for scp dual driver
3. merge mtk_scp_dual.c and mtk_scp_subdev.c to mtk_scp.c

Hello TingHan,

Can you please address the comments on patch [05/11] and send a new version ASAP?
That's the only remaining issue, so after that the series should be ready.

Thanks,
Angelo

There is also the refactoring work in patch 07, and I expect that to take a
while.

That's right, I forgot about that one. Thanks for that.
