This patch add a DMABUF_DEBUG_ADVANCED to try to attach and map
dmabufs who have no valid scatter list table.
Update the rk_dmabuf_procfs node to be a directory tree as:
/proc/rk_dmabuf/
/proc/rk_dmabuf/dev
/proc/rk_dmabuf/sgt
/proc/rk_dmabuf/size
The "dev" to show all attached devices, such as:
ffffff816f8bb600 (null) system-uncached 8288 KiB display-subsystem fb000000.gpu fb000000.gpu
The "sgt" to show scatter list table address range, such as
ffffff8124856200 (null) system-uncached 52 KiB 0: 0x00000001712d0000..0x00000001712d0fff ( 4 KiB)

RK3568 usb phy0 and phy1 linestate irq can be set as
wakeup source, but the default linestate filter time
is based on the usb phy grf pclk 100MHz. So it needs
to reconfigure the linestate filter time base on 32KHz
clk when enter deep sleep.
In addition, it needs to enable the host port (usb3
host1 and usb2 host1) wakeup irq because of legacy
reason.

If miss isoc event happens, the current code just set
the req status to -EXDEV and giveback the req to the usb
gadget driver, and then stop the active transfer with the
cmd DWC3_DEPCMD_ENDTRANSFER and wait for a XferNotReady
event to restart a transfer again. However, for isoc
ep in transfer, it cause to lost the isoc data of the
req.
This patch moves the miss isoc req to pending_list in
order to restart transfer immediately instead of give
back the req to the usb gadget driver.

The commit a7027ca69d ("usb: dwc3: gadget: Give back
staled requests") move all started request to cancelled
list and expect to give back all the started requests.
However, it fails to give back the started requests
if the dep->flags isn't set to DWC3_EP_TRANSFER_STARTED,
in this case, we need to skip the trbs and giveback the
req. And we also need to skip the trbs of the req in the
pending_list to make the dequeue pointers useless.

1.Some 8K frames took more than 200ms to decode,causing software timeout.
Solution:
Increase the software timeout threshold to 500ms
2.After power off av1dec, read/write reg in cache irq causing kernel
crash.
Solution:
There are two irq for av1:
a. vcd_irq is decode irq what we need to care about.
b. cache irq what we do not need to care about.
So disable the cache irq temporarily.

at the beginning of upcoming request, which is the same way
we did for unbusy check in the past. By doing that, we can

In a test-case with an otg cable hot plug stress test
