UPSTREAM: drm: Implement drm_modeset_lock_all_ctx()

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()

arm64: dts: rockchip: Provide power-domains for sd/sdio/emmc/pcie

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.

UPSTREAM: nvmem: core: remove regmap dependency

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.

FROMLIST: extcon: Add the synchronization extcon APIs to support the notification

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);

FROMLIST: extcon: Add the extcon_type to gather each connector into five category

This patch adds the new extcon type to group the each connecotr
into following five category. This type would be used to handle
the connectors as a group unit instead of a connector unit.
- EXTCON_TYPE_USB  : USB connector
- EXTCON_TYPE_CHG  : Charger connector
- EXTCON_TYPE_JACK : Jack connector
- EXTCON_TYPE_DISP : Display connector
- EXTCON_TYPE_MISC : Miscellaneous connector

Also, each external connector is possible to belong to one more extcon type.
In caes of EXTCON_CHG_USB_SDP, it have the EXTCON_TYPE_CHG and EXTCON_TYPE_USB.

usb: dwc3: core: support DRD mode switch with extcon notifier

This patch register extcon notification for DRD mode.
If extcon cable state is EXTCON_USB, means that an USB
peripheral cable connected, and we need to set DWC3 work
in device mode. If extcon cable state is EXTCON_USB_HOST,
means that an USB host cable connected, and we need to
set DWC3 work in host mode.

And we need to register different notifier block for
EXTCON_USB notifier and EXTCON_USB_HOST notifier，because
if multiple notifiers registered with the same notifier
block, it will cause kernel crash on notification events.

UPSTREAM: extcon: link devres into core module

Splitting the resource-managed functions into a separate module
means that the extcon core now fails to build because the internal
"extcon_dev_allocate" symbol is not exported:

ERROR: extcon_dev_allocate [drivers/extcon/devres.ko] undefined!

My guess is that the intention was not to have two separate
modules (which could be fixed by adding an export, plus the
normal MODULE_AUTHOR/MODULE_LICENSE/... fields), but have two
source files in the same module.

This fixes the Makefile accordingly, making the name of the
module extcon_core.ko, which is created from building both
extcon.c and devres.c.

UPSTREAM: extcon: Remove the deprecated extcon functions

This patch removes the deprecated extcon functions using string type
to identify the type of external connector. The Commit 2a9de9c0f08d61
("extcon: Use the unique id for external connector instead of string)
uses the unique id to separate the type of external connector instead of
string name.
- extcon_register_interest()
- extcon_unregister_interest()
- extcon_set_cable_state()
- extcon_get_cable_state()

And, extcon_register_interest() finds the first extcon device to include the
requested external connector from extcon client device and then register the
notifier if extcon device argument is NULL. Instead, extcon_register_notifier()
supports this feature.

But, this patch remains the deprecatd function definition to prevent
the build break.
