As the Table 4-24 in eDP 1.4 spec, the Sink device can only support
Main-Link rate selection via SUPPORTED_LINK_RATES when the value of
DPCD MAX_LINK_RATE is 00h. If MAX_LINK_RATE and SUPPORTED_LINK_RATES
are both non-zero, the Sink device can support both methods.
In practice, if MAX_LINK_RATE is not 00h and SUPPORTED_LINK_RATES
contains non-zero values, sometimes the sink device can only support
to set link rate via LINK_BW_SET. In such case, there will be errors
if set the link rate read from SUPPORTED_LINK_RATES to LINK_RATE_SET.
The panel vendor may explain this is to ensure the same Sink firmware
remains compatible across different versions of the eDP spec. Or the
Main-Link rate selection method has not been fully verified.
In order to avoid these unexpected cases, MAX_LINK_RATE/LINK_BW_SET
method will be selected first if MAX_LINK_RATE is non-zero for eDP
panels that support v1.4 or higher.

The utmi iddig signal of RK3506 OTG1 is left floating by default.
Even when the system is suspended and the logic is powered off,
once the system resume and the clock is enabled, the controller's
current mode will be set to Host mode by default, causing dwc2
fail to reinitialize.
To resolve this issue, we found that the ForceHstMode bit in the
GUSBCFG register returns to its default value of 0 after the logic
is powered off. Once the logic power is restored, this bit does not
automatically return to 1. Therefore, we can use this bit to
determine whether the logic has been powered off when dr_mode is
set to Host.

The deadlock can occur due to a recursive lock acquisition of
`cros_typec_altmode_data::mutex`.
The call chain is as follows:
1. cros_typec_altmode_work() acquires the mutex
2. typec_altmode_vdm() -> dp_altmode_vdm() ->
3. typec_altmode_exit() -> cros_typec_altmode_exit()
4. cros_typec_altmode_exit() attempts to acquire the mutex again
To prevent this, defer the `typec_altmode_exit()` call by scheduling
it rather than calling it directly from within the mutex-protected
context.

(cherry picked from commit 099cf1fbb8afc3771f408109f62bdec66f85160e)
Although some Type-C DRD devices that do not support the DP Sink
function (such as Huawei Mate 40Pro), the Source Port initiates
Enter Mode CMD, but the device responds to Enter Mode ACK, the
Source port then initiates DP Status Update CMD, and the device
responds to DP Status Update NAK.
As PD2.0 spec ("6.4.4.3.4 Enter Mode Command")，A DR_Swap Message
Shall Not be sent during Modal Operation between the Port Partners.
At this time, the source port initiates DR_Swap message through the
"echo device > /sys/class/typec/port0/data_role" command to switch
the data role from host to device. The device will initiate a Hard
Reset for recovery, resulting in the failure of data role swap.
Therefore, when DP Status Update NAK is received, Exit Mode CMD is
initiated to exit the currently entered DP altmode.

As PD2.0 spec ("6.5.6.2 PSSourceOffTimer")，the PSSourceOffTimer is
used by the Policy Engine in Dual-Role Power device that is currently
acting as a Sink to timeout on a PS_RDY Message during a Power Role
Swap sequence. This condition leads to a Hard Reset for USB Type-A and
Type-B Plugs and Error Recovery for Type-C plugs and return to USB
Default Operation.
Therefore, after PSSourceOffTimer timeout, the tcpm state machine should
switch from PR_SWAP_SNK_SRC_SINK_OFF to ERROR_RECOVERY. This can also
solve the test items in the USB power delivery compliance test:
TEST.PD.PROT.SNK.12 PR_Swap – PSSourceOffTimer Timeout

If hdmi uboot logo is disabled and hdmi resolution is HDMI 2.0
resolution(such as 4k60), hdmi->logo_plug_out will be set to true
and won't be clear before hdmi is enabled. After hdmi is enabled,
hdmi->disabled is set to false, and then mode_changed is set to
true. hdmi will be disabled and enabled again.
hdmi->logo_plug_out is mainly used to determine whether hdmi has
been plugged from the end of uboot to the completion of kernel
driver initialization when the uboot logo is enabled. So when
setting it to true, it is necessary to determine whether the
uboot logo is enabled.
