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

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

[Gupta, Ramesh]

All,

The patch set provides DVFS and offmode support for bridgedriver.
These patches to be applied on top of the pm branch. Currently 
Some times we have observed issues like MMU fault and DSP Reset on setting VDD1 to OPP1.

Looks like the drop in voltage to DSP core causing the issue. With a slight increase in VDD1 voltage level for OPP1 [patch 3/3] solving the issue, We are investigating further into this. 

[PATCH 1/3]DSPBRIDGE-Offmode-and-DVFS-Support.patch
[PATCH 2/3]DSPBRIDGE-DVFS-and-OFF-mode-support-with-OPP2.patch
[PATCH 3/3]Boosting-OPP1-voltage-level.patch

Ramesh,

The latest operating condition addendum for 3430 specifies VDD1 OPP1 voltage
to be .975 and OPP2 to be 1.05. Same for VDD2. Rest OPP's remain 
the same. I will send a patch on PM branch to update this and that sould
solve your problem.

regards,
Rajendra

[Gupta, Ramesh]

All,
Looks like there was some issue with git-send-email configuration, It didn't reach the list, I resent the same.

Thanks

Thanks for looking into this, yeah this should resolve my issue with OPP1,
I will wait for your patches.

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

[Gupta, Ramesh]

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
