Hi Dave,
A few misc fixes
The following changes since commit e319a1b956f785f618611857cd946dca2bb68542:
drm/msm: add IOMMU_SUPPORT dependency (2020-12-05 08:25:52 -0800)
are available in the Git repository at:

for you to f
irq_hpd event can only be executed at connected state. Therefore
irq_hpd event should be postponed if it happened at connection
pending state. This patch also make sure both link rate and lane

There is HPD unplug interrupts missed at scenario of an irq_hpd
followed by unplug interrupts with around 10 ms in between.
Since both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts,
irq_hpd handler should not issues either aux or sw reset to avoid
following unplug interrupt be cleared a
Both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts.
Therefore irq_hpd handler should not issues either aux or sw reset
to avoid following unplug interrupt be cleared accidentally.
