Subject: [PATCH v6 0/4] Add remoteproc driver for DSP on i.MX
Date: Mon, 11 Oct 2021 17:20:11 +0800	[thread overview]
Message-ID: <1633944015-789-1-git-send-email-shengjiu.wang@nxp.com> (raw)

Provide a basic driver to control DSP processor found on NXP i.MX8QM,
i.MX8QXP, i.MX8MP and i.MX8ULP.

Currently it is able to resolve addresses between DSP and main CPU,
start and stop the processor, suspend and resume.

The communication between DSP and main CPU is based on mailbox, there
are three mailbox channels (tx, rx, rxdb).

This driver was tested on NXP i.MX8QM, i.MX8QXP, i.MX8MP and i.MX8ULP.

changes in v6:
- fix the apply issue for linux-next
- add if/then schema according to Rob's comments

changes in v5:
- refine driver according to Mathieu's comments

changes in v4:
- merge binding doc to fsl,dsp.yaml for Rob's comments

changes in v3:
- Add this cover letter
- refine clock-names according to Rob's comments
- move common struct from imx_rproc.c to header file
- add IMX_RPROC_SCU_API enum item
- refine driver according to Mathieu's comments

changes in v2:
- change syscon to fsl,dsp-ctrl
- add items for clock-names
