This patch fixes a sparse warning in the omap remoteproc code
when OMAP_REMOTEPROC is disabled.
include/linux/platform_data/remoteproc-omap.h:76:13: warning: symbol
'omap_rproc_reserve_cma' was not declared. Should it be static?

the phandle + args specifier. The latter function is different
from the existing non-DT function, in that the specifier is
relative to the hwlock device instead of being a global lock id
registered with the core.

AM33XX device family also supports hwspinlocks. The IP
is identical to that of OMAP4/OMAP5, except for the
number of locks.

Jassi,
See how mailbox_startup() tries to balance mbox-ops-startup() and
mailbox_fini() the mbox-ops-shutdown() That's very fragile and the
cause of imbalance between rpm enable/disable, unless your clients are
buggy.
Yeah, it is kinda messed up in the existing code, the startup defined
from the MSM HW Mutex driver support series
in [1]).
