61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

4a4deb870f remoteproc: stm32: track the coprocessor state in a backup register
Update the dedicated backup register to track the coprocessor state and
rely on that register to compute the .is_running() value (which expects
a return value of 0 -not 1- if the processor is running).

14d963d1b5 remoteproc: elf_loader: Always check the validity of the image before loading
rproc_elf32_load_image() rely on user to send a valid address for elf loading.
Instead do a sanity check on the address passed by user. This will help
all rproc elf users to not call sanity_check explicitly before calling
elf_loading.

c08eb93626 remoteproc: ops: Add elf section size as input parameter to device_to_virt api
Introduce a new parameter "size" that accepts size of the region to
remoteproc ops callback device_to_virt(). This can enforce more checks
on the region that device_to_virt() is dealing with.
