media: s5p-mfc: Add support for V4L2_MEMORY_DMABUF type
MFC driver supports only MMAP operation mode mainly due to the hardware
restrictions of the addresses of the DMA buffers (MFC v5 hardware can
access buffers only in 128MiB memory region starting from the base address
of its firmware). When IOMMU is available, this requirement is easily
fulfilled even for the buffers located anywhere in the memory - typically
by mapping them in the DMA address space as close as possible to the
firmware. Later hardware revisions don't have this limitations at all.
The second limitation of the MFC hardware related to the memory buffers
is constant buffer address. Once the hardware has been initialized for
operation on given buffer set, the addresses of the buffers cannot be
changed.
With the above assumptions, a limited support for USERPTR and DMABUF
operation modes can be added. The main requirement is to have all buffers
known when starting hardware. This has been achieved by postponing
hardware initialization once all the DMABUF or USERPTR buffers have been
queued for the first time. Once then, buffers cannot be modified to point
to other memory area.
This patch also removes unconditional USERPTR operation mode from encoder
video node, because it doesn't work with v5 MFC hardware without IOMMU
being enabled.
In case of MFC v5 a bidirectional queue flag has to be enabled as a
workaround of the strange hardware behavior - MFC performs a few writes
to source data during the operation.

drm/exynos: ipp: Add IPP v2 framework
This patch adds Exynos IPP v2 subsystem and userspace API.
New userspace API is focused ONLY on memory-to-memory image processing.
The two remainging IPP operation modes (framebuffer writeback and
local-path output with image processing) can be implemented using
standard DRM features: writeback connectors and additional DRM planes with
scaling features.
V2 IPP userspace API is not compatible with old IPP ioctls. This is a
significant change, but the old IPP subsystem in mainline Linux kernel was
partially disfunctional anyway and not used in any open-source project.
V2 IPP userspace API is based on stateless approach, which much better fits
to memory-to-memory image processing model. It also provides support for
all image formats, which are both already defined in DRM API and supported
by the existing IPP hardware modules.
The API consists of the following ioctls:
- DRM_IOCTL_EXYNOS_IPP_GET_RESOURCES: to enumerate all available image
processing modules,
- DRM_IOCTL_EXYNOS_IPP_GET_CAPS: to query capabilities and supported image
formats of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_GET_LIMITS: to query hardware limitiations for
selected image format of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_COMMIT: to perform operation described by the
provided structures (source and destination buffers, operation rectangle,
transformation, etc).
The proposed userspace API is extensible. In the future more advanced image
processing operations can be defined to support for example blending.
Userspace API is fully functional also on DRM render nodes, so it is not
limited to the root/privileged client.
Internal driver API also has been completely rewritten. New IPP core
performs all possible input validation, checks and object life-time
control. The drivers can focus only on writing configuration to hardware
registers. Stateless nature of DRM_IOCTL_EXYNOS_IPP_COMMIT ioctl simplifies
the driver API. Minimal driver needs to provide a single callback for
starting processing and an array with supported image formats.

Input: stmfts - force async driver probe to avoid 2s delay on boot
Executing stmfts_power_on() function lasts over 2 seconds, what
significantly slows down the boot process if driver is compiled in.
Avoid this delay by forcing this driver to be probed asynchronously.

drm/bridge/sii8620: use micro-USB cable detection logic to detect MHL
Currently MHL chip must be turned on permanently to detect MHL cable. It
duplicates micro-USB controller's (MUIC) functionality and consumes
unnecessary power. Lets use extcon attached to MUIC to enable MHL chip
only if it detects MHL cable.

extcon: add possibility to get extcon device by OF node
Since extcon property is not allowed in DT, extcon subsystem requires
another way to get extcon device. Lets try the simplest approach - get
edev by of_node.

dt-bindings: add bindings for USB physical connector
These bindings allow to describe most known standard USB connectors
and it should be possible to extend it if necessary.
USB connectors, beside USB can be used to route other protocols,
for example UART, Audio, MHL. In such case every device passing data
through the connector should have appropriate graph bindings.

ARM: dts: exynos: Add missing interrupts property to PMIC on Trats board
PMIC node requires external interrupts for proper operation, but property
defining them was missing. This was probably caused by a limited support
for interrupts from more than one parent, which was not possible to define
when support for this board was added. Fix this by adding
'interrupt-extended' property and properly define interrupt lines for PMIC
node.
