----------------------------------------------------------------
remoteproc updates for v5.7

This introduces a range of improvements to the OMAP remoeteproc driver;
among other things adding devicetree, suspend/resume and watchdog
support, and adds support the remoteprocs in the DRA7xx SoC.

It introduces support for 64-bit firmware, extends the ELF loader to
support this and fixes for a number of race conditions in the recovery
handling.

It introduces a generic mechanism to allow remoteproc drivers to sync
state with remote processors during a panic, and uses this to prepare
Qualcomm remote processors for post mortem analysis.

Finally it introduces fixes to cleanly recover from crashes in the modem
firmware on production Qualcomm devices.

[PATCH] remoteproc/omap: Fix set_load call in omap_rproc_request_timer

[Nathan Chancellor]

When building arm allyesconfig:

drivers/remoteproc/omap_remoteproc.c:174:44: error: too many arguments
to function call, expected 2, have 3
        timer->timer_ops->set_load(timer->odt, 0, 0);
        ~~~~~~~~~~~~~~~~~~~~~~~~~~                ^
1 error generated.

This is due to commit 02e6d546e3bd ("clocksource/drivers/timer-ti-dm:
Enable autoreload in set_pwm") in the clockevents tree interacting with
commit e28edc571925 ("remoteproc/omap: Request a timer(s) for remoteproc
usage") from the rpmsg tree.

This should have been fixed during the merge of the remoteproc tree
since it happened after the clockevents tree merge; however, it does not
look like my email was noticed by either maintainer and I did not pay
attention when the pull was sent since I was on CC.

Thanks, Nathan. Also throws up with omap2plus_defconfig.

Thanks, I've taken this patch directly into my tree since it was my
merge that screwed up.
