Hi Paul & Kevin,
Here are a reset management series.
- The first patch will be removed as soon as we will have the proper
OMAP4 support for the prm_xxx accessors.
- The second one is adding hardreset support in order to allow
syslink driver to manage properly the DSP and IPU processor
reset.
- The last one is forcing a sofreset after the first init.
Some IP might require sofreset after each wakeup
from power domain OFF mode. That still needs to be confirm.
Tested on PAB board using OMAP4 ES1.0 GP device
Patches are based on lo/for-next + for-next-fixes and are available here:
git://dev.omapzoom.org/pub/scm/swarch/linux-omap-adv.git pm-wip/hwmods-reset
Regards,
Benoit
