We read pingpong status while handling axi and stats irqs
in tasklet. Due to scheduling delays in tasklet pingpong status is
changing by the time we read. So, read ping pong status in ISR
and forward it to tasklet.

After part I authentication, SW DDC is not disabled and because of
this, we observe arbitration issues during part III authentication.
Disable SW DDC before starting part III of HDCP authentication.
Fail part II of authentication with repeater if its device count is zero.

Display Port driver never supported YC420 formats.
Also w.r.t to display quality, 4K30 RGB 8bit is
better than 4K60 YC420 8bit.
So, do not include edid modes(VICs) from YC420 Video
Data Block while parsing EDID.

Clear PP features dirty flags only when they are programmed, based on
programming stage, i.e. clear dirty flags of features programmed in
early stage after early stage programming and clear dirty flags of
features programmed in deferred stage after their actual programming
is complete.
Clearing the flags in one go is resulting in missing programming of
features designated to be programmed in early stage, if the dirty flags
are updated in between the stages.

Configure all I2C instances of SDM660, MSM8996 and MSM8998 for
SW bit banging based bus recovery mechanism. HW recovery may
not work as expected when HW samples the data line and finds
it low during particular clocking period of the recovery.
Use SW bit banging instead, where SW generate clock pulses and
sniff data line until data line is released by the slave.
