Rajat Gupta ecc89334b0 disp: msm: dp: add error handling for host init failures
Add error handling mechanism in host init function to take necessary
action upon failure. For example, power init can fail if we try to
do host_init in between PM suspend. In this case sink sends an hpd
irq with hpd_high equals to 0 and hpd_high equals to 1, after which
ADSP sends the events to DP driver. Now as apps core is in PM suspend
all the devices are put to suspend state and cannot be resumed if
their disable_depth is greater than 1. When driver tries to process
the hpd_high equals to 1 and does host_init in between PM suspend,
it sometimes leads to power init module failure. Inadequate handling
of host init failure as described can lead to a NOC error.
