It's too late to set the aux channel polarity. Some
sink device will not send attention cmd to indicate
hpd plug event. Setting the aux channel polarity earlier.
When detecting the connected status is disconnected,
Setting the gpio status to low.

PCIe need pipe clock for interface with phy;
Note that pcie controller also need its clock(has been set critical)
ACLK_PHP_GIC_ITS, and ACLK_PCIE_BRIDGE(has been set as parent).

Compared to 4.19, there are many new algorithm boundary
condition tests in 5.10. Drivers need to be fixed to
pass these tests and increase driver robustness.

When use Typc-C Interface, after detect CC connect, we assume
the usbdp phy can be use as multi-function(both usb and dp use)
and init the phy in multi-function mode. If the sink only
support only dp function, we need reinit the usbdp phy only dp
function.
When enter dp mode, config the pin assignment, get the attention
cmd from sink, tcpm will callback the mux set. But we only need
the info when hpd is true.

Generally, bq25700 is only source for USB VBUS, bq25700 should
respond all EXTCON_USB_VBUS_EN requests.
And at OTG mode, there may be no EXTCON_USB_HOST_EN changes,
in this case, USB always keeps vbus output even if it used
as device mode.

This patch try to fix this issue by caching the dma-buf attachments and
stores the cache list to dtor_data of dma-buf structor. The dma-buf
attach with cache will try to find cached attachment first and return
the valid instance.
This patch also store the deattch operation to dtor of dma-buf structor
by dma_buf_set_destructor.

dma-buf destructor support is useful as it allows clients an opportunity
to undo any attributes, such as security attributes, they have applied to
the dma-buf's memory.
The destructor is called when the dma-buf is freed, if the destructor
returns an error the dma-buf's exporter release function is not called in
order to ensure that memory which has not been properly cleaned up isn't
returned to the system.

This patch aims to configure usb for better compatibility.
1. Set ssc downward spread spectrum.
2. Enable the adaptive Continuous Time Linear Equalizer (CTLE).
3. Set ssc to 31.5KHz for 24MHz ref clk.
4. Adjusts the PLL the parameters for USB Rx to pass the
Receiver Jitter Tolerance Test, and it's helpful to
improve the USB 3.0 signal compatibility.
