- Deleted the &rockchip_suspend node and all suspend-related GPIO/IO
configurations to clean up the device tree.

When using the ZME algorithm for scaling, the scaling config needs to
be adjusted to ensure performance:
If plane height >= half of display height:
- Use gt4 when down-scaling ratio > 8×
- Use gt2 when down-scaling ratio > 4×
Otherwise:
- Use gt4 when down-scaling ratio > 6×
- Use gt2 when down-scaling ratio > 3×

When sample rate changes, a reset operation is performed, and another
reset occurs after debouncing. This results in less data being read
by upper layer, thus triggering an underrun condition.
Therefore, remove reset operation in rk_spdifrx_trigger. Meanwhile,
when sample rate changes, disable dma enable, and after debouncing
completes, notify upper layer via stop_xrun to restart, then enable
dma to resume data transfer.

Add a debounce timer to prevent continuous reporting of SYNC/NSYNC
information during plug-in and unplug operations.
Add the capability to detect non-linear pcm data and sample bit width,
then notify the application layer of the results.
Add a fifo timer to detect real-time data inflow in the rx fifo,
supporting glitch-free sampling rate transitions.
Add a configuration option for the always-on clock feature.

Obtain the transmitter's sample rate through channel status bits,
and use the CDRST register and MCLK to estimate the sample rate.
Notify sync and sample rate information through controls.The control
names are "RK SPDIFRX SYNC STATUS" and "RK SPDIFRX SAMPLE RATE". The
application layer needs to monitor the controls and read the control
values to obtain the information.
For the sync control, 0 indicates an unlocked state, and 1 indicates
a locked state. The sample rate control has two values, the first
represents the sample rate obtained from the channel status, and the
second represents the estimated sample rate.

If the rockchip,dp-lane-mux property is config in dts, it mean
DP function is used, but the USB function may not be used. It
may be cause cmn ana lcpll lock timeout when initialize phy but
USB function is not used. So just init the phy mode with USB
function when u3-port node is enabled.
If the rockchip,dp-lane-mux property is not in dts, it mean
USB function is used, but the DP function is depend on DP Alt
mode support by sink. If not sink device is disconnected and
force to access DPTX controller register after initialize phy,
The DP function should config, if not config the DPTX controller
register can't be access. So if dp-port node is enabled, init
the phy mode with DP function.

When the serdes-init-sequence is not configured, serdes_init_seq is
a null pointer. However, some serdes initializations do not require
the serdes_init_seq configuration, so the driver needs to execute
normally even when the serdes-init-sequence is not configured.

Some EMMC devices only have one hardware queue, and CMD13 can only
query one slot at a time to transmit data, which cannot be processed
in parallel. The CMD13 query interval can be modified to increase

For split mode, we will update the &drm_display_mode in
&drm_connector_helper_funcs.get_modes() earlier. However, as for
non-split mode, the &drm_display_mode->crtc_clock may be 0, which
make the bandwidth check always pass. It should be reasonable to
use &drm_display_mode.crtc instead of &drm_display_mode.crtc_clock
for bandwidth check.

The DPTX may be not create a drm connector, or it will create
more than 1 drm connector when work in MST mode. So it's better
to create a debugfs directory for the DPTX driver. A drm
encoder is necessary for DPTX driver and the drm connector is
optional, So the debug node add when drm encoder late register
state.

Once the use_os_string flag is set to true for some functions
(e.g. adb/mtp) which need to response the OS string, and then
if we re-bind the ConfigFS gadget to use the other functions
(e.g. hid) which should not to response the OS string, however,
because the use_os_string flag is still true, so the usb gadget
response the OS string descriptor incorrectly, this can cause
the USB device to be unrecognizable on the Windows system.
An example of this as follows:
echo 1 > os_desc/use
ln -s functions/ffs.adb configs/b.1/function0
start adbd
echo "<udc device>" > UDC #succeed
stop adbd
rm configs/b.1/function0
echo 0 > os_desc/use
ln -s functions/hid.gs0 configs/b.1/function0
echo "<udc device>" > UDC #fail to connect on Windows
This patch sets the use_os_string flag to false at bind if
the functions not support OS Descriptors.
