This CEC adapter driver using CEC framework provides CEC
support for SDE hardware. CEC is a protocol that provides
high-level control functions between various audiovisual
products. This adapter is the hardware implementation of
CEC protocol, and its major functionality is to send and
to receive CEC messages.

If the USB Type-C cable is removed while the legacy workaround is
running the IRQ will be ignored and the removal will not be detected.
Check for USB Type-C removal by manually triggering the IRQ when the
legacy workaround finishes.

When calling smmu mapping, if iova is specified directly by user, not
allocated dynamically in dma-mapping.c, smmu driver needs to provide
support for this. This is needed in early display case. In this scenario,
LK has set physical memory to display hardware for fetching, so if iova
is not explicitly specified in kernel, but instead dynamically produced
by "alloc_iova" in dma-mapping.c, display hardware has no chance to know
this new iova, then smmu fault will happen if enabling the iommu stage-1
translation.
To fix this smmu fault problem, add re-routing to the right path when
iova specified by user is not 0 in smmu map/unmap function.

When listener unregister thread wakes up due to some system signals,
but not because ioctl_cnt <=1, it should return directly, instead of
continuing to remove listener list entry, which will lead kernel panic
when another listener receive thread accesses this freed entry.

USB connector HW based thermal regulation is active which will throttle
the input current on USBIN-USBIN configurations. This was enabled for
MID-MID configurations to enable the comparator output for USB connector
temperature mitigation, but since the input is bypassed it does not
throttle the input current. The comparator output is no longer used
since the ADC values are used directly, so neither configuration needs
this HW feature to be enabled.
Remove the write to enable this HW feature.

As per USB PD 3.0 specification the 2-bit Specification Revision field
of a GoodCRC Message does not carry any meaning and Shall be considered
as don't care by the recipient of the Message. Hence set spec revision
to USBPD_REV_20 for GoodCRC message. PD protocol message header defaults
to USBPD_REV_20 which gets updated USBPD_REV_30 if PD 3.0 source capabale
of programmable power supply.

Sigdet under low power (LP) mode will use a less accurate local reference
generation, which is expected to have a little more variation than a
precise reference (normal mode). Update PCIe PHY sigdet to use normal
mode instead of LP to increase accuracy and make sigdet more robust.

Allow re-configuring the DSI, DP and HDMI RCGs even if their
current configuration matches that of the requested frequency.
This is to work around the MM RCGs being latched to run off of
XO by default after an MM GDSC power collapse.
