[v2,0/4] Add support of mt8183 APU

Message

Some Mediatek's SoC have an Accelerated Processing Unit.
This adds support of the one available in the mt8183
(aswell some derivative SoC).

This series depends on two other series:
- Mediatek MT8183 scpsys support  
- arm64: dts: Add m4u and smi-larbs nodes for mt8183

Changes in v2:
- Drop the workarounds needed to load bad firmwares
- There are many name for the APU (most common one is VPU).
  Rename many functions and dts nodes to be more consistent.
- Use the bulk clock API, and enable / disable clock at a better place
- add few comments explaining how to start the APU
- update the way to use pinctl for JTAG
- fix some minors issues
- fix device tree bindings

Alexandre Bailon (4):
  dt bindings: remoteproc: Add bindings for MT8183 APU
  remoteproc: Add a remoteproc driver for the MT8183's APU
  remoteproc: mtk_vpu_rproc: Add support of JTAG
  ARM64: mt8183: Add support of APU to mt8183

Hi Alexander,

Things have been quite busy over the last 3 weeks, preventing me from
giving your work the attention it deserves.  It is on my radar and will get to
it in the next two weeks.

Thanks,
Mathieu
