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.

The ARM64 Exynos5433 supports PSCI(Power State Coordinate Interface)[1] v0.1.
When PSCI v0.1 is used, the device-tree should contain the specific entry

support the cpuidle and suspend execution on Exynos5433 SoC.
The 'cpu_suspend' of psci is originally intended for use in idle subsystems.
Although the cpuidle and suspend-to-RAM framework have separate routine

the separate the entry point such as 'system_suspend' on PSCI v1.0.
So, the 'cpu_suspend' of PSCI v0.1 on Exynos5433 is used for both

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.

interrupting the transfer. Moreover documentation says that
such state can be caused by slave clock stretching, and should not be
treated as an error during transaction. The only place it indicates
an error is just before starting transaction. In such case bus recovery
procedure should be performed - master should pulse SCL line nine times
and then send STOP condition, it can be repeated until SDA goes high.
The procedure can be performed using manual commands HSI2C_CMD_READ_DATA
and HSI2C_CMD_SEND_STOP.

i2c: exynos5: change internal transmission timeout to 100ms
Exynos-I2C uses default timeout of 1 second for the whole transaction,
including re-transmissions due to arbitration lost errors (-EAGAIN).
To allow re-transmissions driver's internal timeout should be significantly
lower, 100ms seems to be good candidate.

ARM: exynos_defconfig: Enable CONFIG_EXYNOS_IOMMU
EXYNOS_IOMMU is disabled in exynos_defconfig since it was known to cause
boot failures on Exynos Chromebooks. The recommendation was for IOMMU to
be enabled manually on systems as needed.
A recent exynos_drm change added a warning message when EXYNOS_IOMMU is
disabled. It is necessary to enable it to avoid the warning messages.
A few initial tests have shown that enabling EXYNOS_IOMMU might be safe
on Exynos Chrome-books.
Due to some other changes in the order of operations during boot
process, power domains are initialized very early and because of the
temporary lack of devices (which are not yet added to the system), are
turned off.
This practically stops FIMD for scanning framebuffer very early during
boot, before IOMMU gets initialized and "solves" the issue, which was
the reason to disable Exynos IOMMU by default on Exynos Snow Chromebooks.
