Subject: [PATCH v3 00/11] Add support for MT8195 SCP 2nd core

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.

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

Tinghan Shen (11):
  dt-bindings: remoteproc: mediatek: Give the subnode a persistent name
  dt-bindings: remoteproc: mediatek: Support MT8195 dual-core SCP
  arm64: dts: mt8195: Add SCP core 1 node
  remoteproc: mediatek: Remove redundant rproc_boot
  remoteproc: mediatek: Add SCP core 1 register definitions
  remoteproc: mediatek: Add MT8195 SCP core 1 operations
  remoteproc: mediatek: Probe MT8195 SCP core 1
  remoteproc: mediatek: Control SCP core 1 boot by rproc subdevice
  remoteproc: mediatek: Setup MT8195 SCP core 1 SRAM offset
  remoteproc: mediatek: Handle MT8195 SCP core 1 watchdog timeout
  remoteproc: mediatek: Refine ipi handler error message
