Merge the baseline rpmsg and remoteproc patches into the RPMsg domain
integration branch: rpmsg-ti-linux-4.19.y. These are baselined on the
vanilla v4.19 kernel and includes some upstream backports from v4.20
kernel. The patches also include few additional enhancements to
rpmsg/remoteproc cores.
The enhancements to remoteproc core include adding API to allow rpmsg
bus drivers to be able to retrieve a SoC-wide unique rproc id for usage
by some rpmsg drivers/userspace stacks and an API to perform physical
to device address translations. Also included is a minor improvement
that checks for NULL firmwares on the sysfs 'firmware' file interface.
The enhancements to rpmsg core are primarily about adding a new descriptor
field to the rpmsg channel device to allow multiple instances of a rpmsg
client driver, and is an enhanced version of the equivalent feature on
4.14 kernel providing backward compatibility.
Note that the support for rpmsg buffers in HIGHMEM and/or regular
carveouts is already supported in mainline kernel (default CMA pools
in Linux are allocated from HIGHMEM range since 3.18 if the platform
has large enough memory for HIGHMEM).
* 'rpmsg-linux-4.19.y' of git://git.ti.com/rpmsg/rpmsg:
rpmsg: add a description field
samples/rpmsg: Introduce a module parameter for message count
remoteproc: add an api to do pa to da conversion
remoteproc: add api for retrieving a rproc unique id
remoteproc: add name in rproc_mem_entry struct
remoteproc: Check for NULL firmwares in sysfs interface
rpmsg: char: Migrate to iter versions of read and write
