Subject: [PATCH v2 0/4] Add support of mt8183 APU
Date: Thu, 10 Sep 2020 15:01:44 +0200 [thread overview]
Message-ID: <20200910130148.8734-1-abailon@baylibre.com> (raw)
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
