When different processes import buffers, the same virtual address may
exist, so current needs to be used for judgment.

when dsi controller work in cmd mode, it will tell vop work in
hold mode and must config te signal for vop.
when rk3588 dsi interface connect to rkx111 and work in cmd mode,
rkx111 will not provided a te signal, so it need disable hold
mode and transfer this config to vop.

The serdes version 1 have a bug when enable video suspend function,
which is target to enhance the i2c frequency when transfer video
stream. In order to enhance i2c frequency as far as possible, a
workaround ways is provided to do this thing, which is to reduce
the video packet length. the formula as follow:
length = ((hactive x 24 / 32 / 16) + 15) / 16 * 16
It should be noted that reducing video packet length will consume more
link bandwidth.

The I2S part of RK817 work as slave mode require BCLK on
first, otherwise, there will make the L/R invert.
On the stage hw_params, the BCLK maybe off. so, let's move
it into mute stage to fix this.

Audio Products with AEC require loopback for echo cancellation.
the hardware LP is not always available on some products, maybe
the HW limitation(such as internal acodec) or HW Cost-down.
This patch add support software DLP for such products.

The rk3588 has two ohci controllers, and the ohci_resume()
takes a long time when system resume. Considering that the
delay time in the ohci_resume() is related to controller
hardware, we should not modify the delay time.
This patch enable async suspend for rk3588 ohci controllers,
then they can do asynchronous resume. Note that it generally
is unsafe to permit the asynchronous suspend/resume for ohci
because we can't certain that the PM dependencies of the ohci.
However, for rk3588, we have add device_link between the ohci
and ehci with the commit 68850661b5 ("usb: host: ehci-platform:
Add device_link between the ehci and companion"), so we can
safely enable async suspend/resume for rk3588 ohci.
