From: Rajendra Nayak <redacted> With no driver handling DSP, if brought out of reset, it stays active and does not assert standby. This leads to IVAHD powerdomain not transitioning and hence preventing chip retention. This patch is no longer needed once Paul's powerdomain fixes are merged: http://marc.info/?l=linux-omap&m=133040749621183&w=2 Just provided for testing purposes.
