This patch add support to change LVDS output common mode voltage
and differential voltage using dts prop "inno,lvds-vcom" and
"inno,lvds-vod".
&video_phy0 {
inno,lvds-vcom = <950>; /* 950mV */
inno,lvds-vod = <350>; /* 350mV */
}

For rk3576 and rk3588, vop dclk can be from pll or hdmi phy[except hdmi
2.1(dclk bigger than 597M), the HDMI work at FRL mode], when dclk is
from pll, dclk_parent is equal to dclk, we need clk_round_rate() for
dclk_parent to check whether can support this mode.
1. GPLL/CPLL/VPLL
dclk_parent
dclk
2. xin24m

Test on RK3576 Tablet Android 14 GKI, when plug in U disk,
it will trigger the usb2 phy to do charging detection logic
in the following process.
1. Type-C PD controller chip (e.g HUSB311) detect DFP mode;
2. Type-C tcpm call usb_role_switch_set_role() to notify
the usb controller to set USB_ROLE_HOST;
3. The usb dwc3 controller driver do dwc3_set_mode() to
initialize the controller and phy for host mode;
4. In the __dwc3_set_mode(), it do pm_runtime_get_sync()
-> dwc3_runtime_resume() -> dwc3_resume_common() ->
dwc3_core_init() -> phy_init(dwc->usb2_generic_phy);
5. In the usb2 phy driver, it do rockchip_usb2phy_init()
-> schedule otg_sm_work -> rockchip_chg_detect_work()
6. Detect dcp cable is connected, and call extcon_set_state_sync()
to send charger notification with true state.
Later, if plug out the U disk and plug in a USB charger,
it will fail to send charger notification because its
extcon state still in true state.
To fix this issue, we need to clear the charger state
in the otg_sm_work if it's already in host mode.

R216/R243/R324/R432 are the new recommended link rates in
eDP v1.4, which may be read from DPCD SUPPORTED_LINK_RATES
(0x00010h through 0x0001fh). And set the link rate by DPCD
LINK_BW_SET(0x00100h).

As Table 4-23 in eDP v1.4 spec, the link rate can be
read from SUPPORTED_LINK_RATES(0x00010h through 0x0001fh),
which is required for sink devices.

The bandwidth/lane_count have been got in analogix_dp_detect(),
which is earlier than analogix_dp_full_link_train().
And getting link configs in .detect() will help to
check mode support in .mode_valid().

According to Documentation/driver-api/driver-model/driver.rst,
a warning as follow:
-EPROBE_DEFER must not be returned if probe() has already created
child devices, even if those child devices are removed again
in a cleanup path. If -EPROBE_DEFER is returned after a child
device has been registered, it may result in an infinite loop of
.probe() calls to the same driver.
To avoid this issue, we do the audio init work when register
encoder.

w-hdmi-qp-hdcp device is very easy to register and probe it's
driver, move it out of bind callback to avoid create child device when
hdmi driver or other components run probe(this may cause infinite loop
probe as these components are very easy run into defer probe).

If dw_hdmi_rockchip_bind is bind failed or other related
components(dp/dsi) bind failed, dw_hdmi_rockchip_unbind will
be called, then some resources like hdmi->workqueue will be
destroyed. So we should not reference this resources at ->shutdown.
