Let's be user-friendly and print an actually helpful parameter
description.
This makes modinfo output the debug parameter like this:
parm: debug:Enable debug output, where each bit enables a debug category.
Bit 0 (0x01) will enable CORE messages (drm core code)
Bit 1 (0x02) will enable DRIVER messages (drm controller code)
Bit 2 (0x04) will enable KMS messages (modesetting code)
Bit 3 (0x08) will enable PRIME messages (prime code)
Bit 4 (0x10) will enable ATOMIC messages (atomic code)
Bit 5 (0x20) will enable VBL messages (vblank code) (int)
Changes from v1:
* Fixed s/PRMIE/PRIME typo.
* Add ATOMIC and VBL debug parameter documentation.
* Prefix the continuation lines with two tabs and
removed the last new line.
* Remove spurious whitespace.

This patch adds a method to tuning phy with the following
parameters to improve usb driver strength and increase usb2
compatibility.
1. Set max ODT compensation voltage and current tuning reference.
2. Set max pre-emphasis level.
3. Disable the pre-emphasize in eop state and chirp state
to avoid mis-trigger the disconnect detection and also
avoid hs handshake fail.
We don't enable the phy tuning by default. If you want to
tuning phy, you can add a property "rockchip,u2phy-tuning"
in u2phy node, like this:
&u2phy0 {
rockchip,u2phy-tuning;
};
&u2phy1 {
rockchip,u2phy-tuning;
};

When system enter PM suspend, it will use a flag genpd->suspend_
power_off to disable device power domain operations, and device
can't enable its power domain until complete PM resume, or rather,
until call pm_genpd_complete() to clear suspend_power_off flag.
In some case, e.g. plug in Type-C PD adapter during system suspend,
and then wakeup system, the fusb302 may send notifier to USB/DP
before USB/DP complete PM resume, this may cause USB/DP fail to
enable their power domain.
I don't find a way to make sure USB/DP PM resume, fortunately，
the PM framework provides a flag pm_freezing to indicate that
complete PM resume all of devices.

The cdn_dp_pd_event_work is using drm_helper_hpd_irq_event to update the
connector status, this function is used to update all connectors of
drm_device. Therefore, the detect of other connector will be call, when
cdn_dp_pd_event_work is triggered, every time. It is not necessary, and
it may cause system crash. replace drm_helper_hpd_irq_event with
drm_kms_helper_hotplug_event, only update cdn-dp status.

When type-c vbus output power down or disconnect charging input, the
type-c vbus voltage discharge to 0V take a long time, during this time
residual voltage would affect charge circuit in some platforms（e.g.
rk3399-tve1205g board）. So we need add fast discharge circuit, then use
a gpio control it.

Buck1/2 can be controlled by gpio dvs, this is GPIO specifiers
for 2 host gpio's used for dvs. The format of the gpio specifier depends in
the gpio controller. If DVS GPIOs aren't present, voltage changes will happen
very quickly with no slow ramp time.

the core clock controller but through bits set in the general register
files. Add a clock-type that can control these as well, so that we
don't need to work around them being absent.

flag of emmc_disk was used to indicate that if the main
disk is for rockchip specific as we need to use rk specific
partition layout. But this name is vague and pointless since
the main disk could be sdmmc as we support sdmmc bootup.
Moreover, we could support more types of storage devices, for
instance, NVMe, UFS etc. Let's rename it to better reflect what
it is here.

The driver selects NOP_USB_XCEIV, which can only be built-in if
USB_GADGET is either disabled or also built-in, so with USB_DWC2_PCI=y
and USB_GADGET=m, NOP_USB_XCEIV is also built-in and we get this link
error:
drivers/usb/built-in.o: In function `nop_set_peripheral':
