remoteproc: Remove vdev_to_rvdev and vdev_to_rproc from remoteproc API

2021-10-15T14:49:55+00:00

These both functions are only used by the remoteproc_virtio.
There is no reason to expose them in the API.
Move the functions in remoteproc_virtio.c

remoteproc: omap_remoteproc: simplify getting .driver_data

2021-10-15T14:49:55+00:00

We should get 'driver_data' from 'struct device' directly. Going via
platform_device is an unneeded step back and forth.

remoteproc: qcom_q6v5_mss: Use devm_platform_ioremap_resource_byname() to simplify code

2021-10-15T14:49:55+00:00

In this function, devm_platform_ioremap_resource_byname() should be
suitable to simplify code.

remoteproc: Fix a memory leak in an error handling path in 'rproc_handle_vdev()'

2021-10-15T14:49:55+00:00

If 'copy_dma_range_map() fails, the memory allocated for 'rvdev' will leak.
Move the 'copy_dma_range_map()' call after the device registration so
that 'rproc_rvdev_release()' can be called to free some resources.

Also, branch to the error handling path if 'copy_dma_range_map()' instead
of a direct return to avoid some other leaks.

remoteproc: imx_dsp_rproc: mark PM functions as __maybe_unused

2021-10-14T16:05:21+00:00

When CONFIG_PM_SLEEP is disabled, we get a harmless warning:

drivers/remoteproc/imx_dsp_rproc.c:1145:12: error: 'imx_dsp_resume' defined but not used [-Werror=unused-function]
 1145 | static int imx_dsp_resume(struct device *dev)

drivers/remoteproc/imx_dsp_rproc.c:1110:12: error: 'imx_dsp_suspend' defined but not used [-Werror=unused-function]
 1110 | static int imx_dsp_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~

Mark these as __maybe_unused to get a clean build.

remoteproc: imx_dsp_rproc: Add remoteproc driver for DSP on i.MX

2021-10-12T15:16:58+00:00

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.
