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 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 Shengjiu Wang (4): remoteproc: imx_rproc: Move common structure to header file remoteproc: imx_rproc: Add IMX_RPROC_SCU_API method remoteproc: imx_dsp_rproc: Add remoteproc driver for DSP on i.MX dt-bindings: dsp: fsl: update binding document for remote proc driver .../devicetree/bindings/dsp/fsl,dsp.yaml | 81 +- drivers/remoteproc/Kconfig | 11 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/imx_dsp_rproc.c | 1206 +++++++++++++++++ drivers/remoteproc/imx_rproc.c | 28 +- drivers/remoteproc/imx_rproc.h | 39 + 6 files changed, 1333 insertions(+), 33 deletions(-) create mode 100644 drivers/remoteproc/imx_dsp_rproc.c create mode 100644 drivers/remoteproc/imx_rproc.h
