Subject[PATCH v9 00/11] Add support for MT8195 SCP 2nd core
Date
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.

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
