FROMLIST: phy: rockchip-inno-usb2: add a new driver for Rockchip usb2phy

The newer SoCs (rk3366, rk3399) take a different usb-phy IP block
than rk3288 and before, and most of phy-related registers are also
different from the past, so a new phy driver is required necessarily.

mmc: dw_mmc: fix unmap sg twice when finding data err

DATA_OVER(the same for RI/TI of IDMAC) interrupt may come
up together with data error interrupts. If so, the interrupt
routine set EVENT_DATA_ERR to the pending_events and schedule
the tasklet but we may still fallback to the IDMAC interrupt
case as the tasklet may come up a little late, namely right
after the IDMAC interrupt checking. This will casue dw_mmc
unmap sg twice. We can easily see it with CONFIG_DMA_API_DEBUG
enabled.

UPSTREAM: ASoC: hdmi-codec: Add ELD control

ALSA doesn't know about all the different compressed audio formats,
so there is no interface to let userspace enumerate the formats that
are supported by the connected sink. Exporting the raw ELD bytes to
userspace allows an application to select the appropriate audio format
depending on the current capabilities of the connected HDMI sink device.
Usually userspace then just pretends to ALSA that the data is in one of
the raw 16-bit PCM audio formats and relies on the IEC controls to tell
the sink how to interpret the data.

UPSTREAM: ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders

The hdmi-codec is a platform device driver to be registered from
drivers of external HDMI encoders with I2S and/or spdif interface. The
driver in turn registers an ASoC codec for the HDMI encoder's audio
functionality.

The structures and definitions in the API header are mostly redundant
copies of similar structures in ASoC headers. This is on purpose to
avoid direct dependencies to ASoC structures in video side driver.

 commit ea98491133439773b69345eb9a314fc5f15e07a4)

UPSTREAM: dmaengine: Add transfer termination synchronization support

The DMAengine API has a long standing race condition that is inherent to
the API itself. Calling dmaengine_terminate_all() is supposed to stop and
abort any pending or active transfers that have previously been submitted.
Unfortunately it is possible that this operation races against a currently
running (or with some drivers also scheduled) completion callback.

Since the API allows dmaengine_terminate_all() to be called from atomic
context as well as from within a completion callback it is not possible to
synchronize to the execution of the completion callback from within
dmaengine_terminate_all() itself.

This means that a user of the DMAengine API does not know when it is safe
to free resources used in the completion callback, which can result in a
use-after-free race condition.

This patch addresses the issue by introducing an explicit synchronization
primitive to the DMAengine API called dmaengine_synchronize().

The existing dmaengine_terminate_all() is deprecated in favor of
dmaengine_terminate_sync() and dmaengine_terminate_async(). The former
aborts all pending and active transfers and synchronizes to the current
context, meaning it will wait until all running completion callbacks have
finished. This means it is only possible to call this function from
non-atomic context. The later function does not synchronize, but can still
be used in atomic context or from within a complete callback. It has to be
followed up by dmaengine_synchronize() before a client can free the
resources used in a completion callback.

In addition to this the semantics of the device_terminate_all() callback
are slightly relaxed by this patch. It is now OK for a driver to only
schedule the termination of the active transfer, but does not necessarily
have to wait until the DMA controller has completely stopped. The driver
must ensure though that the controller has stopped and no longer accesses
any memory when the device_synchronize() callback returns.

This was in part done since most drivers do not pay attention to this
anyway at the moment and to emphasize that this needs to be done when the
device_synchronize() callback is implemented. But it also helps with
implementing support for devices where stopping the controller can require
operations that may sleep.
