> Subject: [PATCH 5/5] staging: fsl-mc: Management Complex restool driver
>
> The kernel support for the restool (a user space resource management
> tool) is a driver for the /dev/dprc.N device file.
> Its purpose is to provide an ioctl interface,
> which the restool uses to interact with the MC bus driver
Name of the user space tool should be updated to be current: s/restool/ls-restool/
> and with the MC firmware.
> We allocate a dpmcp at driver initialization,
> and keep that dpmcp until driver exit.
> We use that dpmcp by default.
> If that dpmcp is in use, we create another portal at run time
> and destroy the newly created portal after use.
> The ioctl RESTOOL_SEND_MC_COMMAND sends user space command to fsl-mc
> bus and utilizes the fsl-mc bus to communicate with MC firmware.
> The ioctl RESTOOL_DPRC_SYNC request the mc-bus launch
> objects scan under root dprc.
> In order to support multiple root dprc, we utilize the bus notify
> mechanism to scan fsl_mc_bus_type for the newly added root dprc.
> After discovering the root dprc, it creates a miscdevice
> /dev/dprc.N to associate with this root dprc.
