When charging the battery, I see the SDE_PORTB_HOTPLUG, PORTC, PORTD
and SDE_AUX_MASK bits set (sometimes at different times) at ~20Hz
until the battery is charged, which is disconcerting.
Hotplugging a HDMI cable, SDE_PORTB_HOTPLUG and SDE_AUX_MASK bits are
set once, so we can't mask these on this platform.
Attached are the reg dumps. We see the backlight register
(BLC_PWM_CPU_CTL) and the A surface register (DSPASURF) vary across
multiple reads as expected.
Any ideas?
