RE: [PATCH 0/3] DSPBRIDGE DVFS and Off mode support for bridgedriver

["Gupta, Ramesh" <grgupta@ti.com>]

All,

The patch [PATCH] OMAP3: PM: Update voltage levels for OPP1/2 on VDD1/2 from Rajendra Naik is fixing the OPP1 issues I was seeing. For Bridge DVFS to work [PATCH 1/3]DSPBRIDGE-Offmode-and-DVFS-Support.patch is sufficient from this patch set, I am going to send a single updated patch for DSPBRIDGE DVFS and OFF mode.

Thanks 
Ramesh Gupta G
