ROLE_CONTROL register would not have the actual CC terminations
unless the port does not set ROLE_CONTROL.DRP. For DRP ports,
CC_STATUS.cc1/cc2 indicates the final terminations applied
when TCPC enters potential_connect_as_source/_sink.
For DRP ports, infer port role from CC_STATUS and set corresponding
CC terminations before setting the orientation.

(cherry picked from commit 57ce64668f)
"tReceiverResponse 15 ms Section 6.6.2
The receiver of a Message requiring a response Shall respond
within tReceiverResponse in order to ensure that the
sender’s SenderResponseTimer does not expire."
When the cpu complex is busy running other lower priority
work items, TCPM's work queue sometimes does not get scheduled
on time to meet the above requirement from the spec.
Moving to kthread_work apis to run with real time priority.
Further, as observed in 1ff688209e, moving to hrtimers to
overcome scheduling latency while scheduling the delayed work.
TCPM has three work streams:
1. tcpm_state_machine
2. vdm_state_machine
3. event_work
tcpm_state_machine and vdm_state_machine both schedule work in
future i.e. delayed. Hence each of them have a corresponding
hrtimer, tcpm_state_machine_timer & vdm_state_machine_timer.
When work is queued right away kthread_queue_work is used.
Else, the relevant timer is programmed and made to queue
the kthread_work upon timer expiry.
kthread_create_worker only creates one kthread worker thread,
hence single threadedness of workqueue is retained.

(cherry picked from commit 3ed8e1c2ac)
According to commit 9bde4e671f ("drm/rockchip: vop: fix iommu crash
with async atomic")
These two callback were added to avoid iommu crash on async
commit caused by drm_atomic_clean_old_fb after drm_atomic_async_commit.
drm_atomic_clean_old_fb was removed after commit
e00fb8564e ("drm: Stop updating plane->crtc/fb/old_fb on atomic drivers")
So we can remove them to make life simpler.

As we mask our SDHCI controller as SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN,
host->max_clk is derived from core clock in the first place. Then
f_max works together with it.
If we adjust loader's core clk setting, such as 50MHz, we will get
50MHz for host->max_clk, because .get_max_clock() reads core clk
when probing driver. That will lead f_max be set to 50MHz as well,
no matter if max-frequency is set higher than 50MHz.
We can simple solve this problem by assigning core clk as 200MHz
in the first place and then let max-frequency property takes over
it.

spi, and the alias UCLASS_SPI id is required for part of

There are many kinds of nodes under pinctrl node, such as function
nodes, gpio nodes, and pcfg nodes.
The driver do a match check for the nodes, to ignore the gpio nodes.
This patch try to put the valid check as a function, it's better to
avoid error fix.
