The commit that introduced this flag suggests so.
commit aad70de20fc69970a3080e7e8f02b54a4a3fe3e6 Author: Sekhar Nori <nsekhar@ti.com> AuthorDate: Wed Jul 6 06:01:22 2011 +0000 Commit: Sekhar Nori <nsekhar@ti.com> CommitDate: Fri Jul 8 11:10:09 2011 +0530
davinci: enable forced transitions on PSC
Some DaVinci modules like the SATA on DA850 need forced module state transitions.
Define a "force" flag which can be passed to the PSC config function to enable it to make forced transitions.
Forced transitions shouldn't normally be attempted, unless the TRM explicitly specifies its usage.
ChangeLog: v2: Modified to take care of the fact that davinci_psc_config() now takes the flags directly.
Signed-off-by: Sekhar Nori <nsekhar@ti.com>
I can check without that flag again, but I do recall it being needed.
Thanks, Sekhar
