Subject: ENGR00227965 EPDC: Init sequence leaves EDPC clocks on
X-Git-Tag: v3.0.35-fsl_4.1.0~490

ENGR00227965 EPDC: Init sequence leaves EDPC clocks on

A small logic bug prevents the init sequence from properly turning
off the clocks. This leads to the clocks being always on
if the first update does not complete due to the screen being blanked.
