Subject: [PATCH v1 00/15] Add support for MT8195 SCP 2nd core

The MT8195 System Companion Processor(SCP) is a dual-core RISC-V MCU.
Current mediatek remoteproc driver only supports bring-up single core 
SCP or the 1st core of a dual-core SCP. This series support to bring-up 
the 2nd core of a dual-core SCP.

Tinghan Shen (15):
  dt-binding: remoteproc: mediatek: Support dual-core SCP
  remoteproc: Kconfig: Add mt8195 SCP dual core configuration
  remoteproc: mediatek: Support hanlding scp core 1 wdt timeout
  remoteproc: mediatek: Add SCP core 1 register definitions
  remoteproc: mediatek: Add SCP core 1 driver for dual-core scp
  remoteproc: mediatek: Add SCP core 1 rproc operations
  remoteproc: mediatek: Add SCP core 1 reserved memory support
  remoteproc: mediatek: Add SCP core 1 interrupt support
  remoteproc: mediatek: Register SCP core 1 initialization ipi
  remoteproc: mediatek: Add chip dependent operations for SCP core 1
  remoteproc: mediatek: Add SCP core 1 SRAM offset
  remoteproc: mediatek: SCP core 1 as a rproc subdevice
  remoteproc: mediatek: Wait SCP core 1 probe done
  remoteproc: mediatek: Support rpmsg for SCP core 1
  mfd: cros_ec: Add SCP 2nd core as a new CrOS EC MCU
