UPSTREAM: mmc: sdhci: Fix sdhci_card_busy()

host->card_busy() was introduced for SD voltage switching which checks all
4 data lines.

Increasingly, host->card_busy is being used to poll the the busy signal
which is only data line 0 (DAT[0]).

The current logic in sdhci_card_busy() does not work in that case because
it returns false if any of the data lines is high.  It also ignores
possibilities:
- data lines 1-3 are not connected and could show at any level
- data lines 1-2 can be used by SDIO for other purposes

According to the SD specification, it is OK to check any of the data lines
for voltage switching, so change to use DAT[0] only.

UPSTREAM: drm/rockchip: Use atomic PM helpers

This driver was still using the old legacy helpers and that caused a few
NULL dereferences when trying to call empty callbacks.

v4: - remove redundant code (already provided by atomic helpers)

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().

- 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);

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.
