There are 2 Type-C phy on RK3399, they are almost same, except the

Add a PHY provider driver for the rk3399 SoC Type-c PHY. The USB
Type-C PHY is designed to support the USB3 and DP applications. The
PHY basically has two main components: USB3 and DisplyPort. USB3
operates in SuperSpeed mode and the DP can operate at RBR, HBR and
HBR2 data rates. Hence, create 2 PHY deivces, the phy[0] for DP,
and phy[1] for USB3.

This function is like drm_modeset_lock_all(), but it takes the lock
acquisition context as a parameter rather than storing it in the DRM
device's mode_config structure.
Implement drm_modeset_{,un}lock_all() in terms of the new function for
better code reuse, and add a note to the kerneldoc that new code should
use the new functions.
v2: improve kerneldoc
v4: rename drm_modeset_lock_all_crtcs() to drm_modeset_lock_all_ctx()
and take mode_config's .connection_mutex instead of .mutex lock to
avoid lock inversion (Daniel Vetter), use drm_modeset_drop_locks()
which is now the equivalent of drm_modeset_unlock_all_ctx()
v5: do not take the dev->mode_config.connection_mutex in
drm_atomic_legacy_backoff() since drm_modeset_lock_all_ctx()
already keeps it, enhance kerneldoc for drm_modeset_lock_all_ctx()

The PM domain will be "powered on" once we have registered our PM domain
with genpd and when the device (dw_mmc etc) gets attached to the domain.
The attach occurs when the platform bus'->probe() function get invoked
for the device.
Genpd monitors each device within the domain. To allow it to "power
off", all devices in same domain needs to be runtime PM enabled and
runtime PM suspended.
Due to this, we should be able to deploy genpd support+an updated
DTB, without first having to deploying runtime PM support in the
related drivers. In other words, we could be able to work on these
things almost independently of each other。
So let's only provide power-domains to each devices' node to make
power policy collect the unreferenced ones once avaiable.
But please KEEP IN MIND that this patch doesn't mean we don't support
rpm or any genpd control related stuff on the future, which in other
words means that could be available later.

nvmem uses regmap_raw_read/write apis to read/write data from providers,
regmap raw apis stopped working with recent kernels which removed raw
accessors on mmio bus. This resulted in broken nvmem for providers
which are based on regmap mmio bus. This issue can be fixed temporarly
by moving to other regmap apis, but we might hit same issue in future.
Moving to interfaces based on read/write callbacks from providers would
be more robust.
This patch removes regmap dependency from nvmem and introduces
read/write callbacks from the providers.
Without this patch nvmem providers like qfprom based on regmap mmio
bus would not work.

This patch adds the synchronization extcon APIs to support the notifications
for both state and property. When extcon_*_sync() functions is called,
the extcon informs the information from extcon provider to extcon client.
The extcon driver may need to change the both state and multiple properties
at the same time. After setting the data of a external connector,
the extcon send the notification to client driver with the extcon_*_sync().
The list of new extcon APIs as following:
- extcon_sync() : Send the notification for each external connector to
synchronize the information between extcon provider driver
and extcon client driver.
- extcon_set_state_sync() : Set the state of external connector with noti.
- extcon_set_property_sync() : Set the property of external connector with noti.
For example,
case 1, change the state of external connector and synchronized the data.
extcon_set_state_sync(edev, EXTCON_USB, 1);
case 2, change both the state and property of external connector
and synchronized the data.
extcon_set_state(edev, EXTCON_USB, 1);
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_ID, 1);
extcon_sync(edev, EXTCON_USB);
case 3, change the property of external connector and synchronized the data.
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0);
extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_ID, 1);
extcon_sync(edev, EXTCON_USB);
case 4, change the property of external connector and synchronized the data.
extcon_set_property_sync(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0);

- extcon_get_cable_state_() -> extcon_get_state()
But, this patch remains the old extcon_set/get_cable_state_() functions
to prevent the build break. After altering new APIs, remove the old APIs.
