f5432bfa9d arm64: dts: rockchip: rk3576: fix apb clk to PCLK_HDPTX_APB for hdmi 
The parent clock of PCLK_HDPTX_APB is PCLK_PMUPHY_ROOT,
which must be always on.

In order to reduce power consumption, replace apb clock
PCLK_PMUPHY_ROOT by controllable PCLK_HDPTX_APB in
suspend and plug out.

3191b79344 usb: typec: tcpci_husb311: Support to enable wakeup irq via dts 
The husb311 driver disable irq wakeup if vbus is on
(e.g connect with an U Disk), it aimed to avoid wakeup
system from deep sleep immediately by husb311 irq if
the vbus was powered off during deep sleep.

However, some platforms can keep vbus on during deep
sleep, and it may want to support the husb311 irq to
wakeup system from deep sleep, so this patch adds an
option property "wakeup-source" for this scenario.

dcaa39ee96 video: rockchip: mpp: fix unused buffer move fail issue 
When dmabuf cache disable:
1.move most recently used link node to link tail,
instead of calculate oldest ktime when buffer full.
2.For those buffer import by ioctl MPP_CMD_TRANS_FD_TO_IOVA,
move to static_list instead of used_list,
and don't increase extra kref,
so that it will release when user space call
ioctl MPP_CMD_RELEASE_FD.

c5be1bded8 drm/rockchip: dsi2: add support PSR for mipi command mode 
As described in:
https://patchwork.freedesktop.org/patch/msgid/20190228210939.83386-2-sean@poorly.run

From the driver's perspective, this works like a regular disable/enable
cycle. The driver need only check the 'psr_transition' state in
connector_state and keep the panel turned on when in .disable(), while
everything else will cycle off as normal. If drivers want more control,
they can use the psr_transition state to enter a low-power state to
minimize PSR exit time.

While this carries the PSR moniker, it is not specific to the
DisplayPort technology. This can be used for power savings
with other types of self refresh, such as MIPI command mode.

The DP MST bridge device may be a branch device, such as DP
MST HUB, the branch unit in DP MST monitor, A DP MST bridge
chip and so on.

When a sink device connected to the DP MST bridege device's
output port, The sink device may receive the stream from
steram0/1/2.

When the DP MST bridge device is a bridge chip and the output
port attach to a fixed device(another bridge device or panel).
The output port may want bind itself to a fixed stream.

To satisfy this requirement, The prop
"rockchip,mst-fixed-ports" is used to do it.
For example, define as follow:
rockchip,mst-fixed-ports = <1 2 3>;
It mean that:
DP Port stream0 --> DP MST bridge Output Port1
DP Port stream1 --> DP MST bridge Output Port2
DP Port stream2 --> DP MST bridge Output Port3
