Back-merge tag 'v4.7-rc5' into drm-next
Linux 4.7-rc5
The fsl-dcu pull needs -rc3 so go to -rc5 for now.
Drop dmtimer usage for pulse timer in favor of hrtimer. That allows
removing PWM dmitimer platform data usage.

The ir-rx51 driver for n900 has been disabled since the multiarch
changes as plat include directory no longer is SoC specific.
Let's fix it with minimal changes to pass the dmtimer calls in
pdata. Then the following changes can be done while things can
be tested to be working for each change:
1. Change the non-pwm dmtimer to use just hrtimer if possible
2. Change the pwm dmtimer to use Linux PWM API with the new
drivers/pwm/pwm-omap-dmtimer.c and remove the direct calls
to dmtimer functions
3. Parse configuration from device tree and drop the pdata

Controls are applied to the hardware in the configure operation of the
VSP entities, which is only called when starting the video stream. To
enable runtime modification of controls we need to call the configure
operations for every frame. Doing so is currently not safe, as most
parameters shouldn't be modified during streaming. Furthermore the
configure operation can sleep, preventing it from being called from the
frame completion interrupt handler for the next frame.
Fix this by adding an argument to the configure operation to tell
entities whether to perform a full configuration (as done now) or a
partial runtime configuration. In the latter case the operation will
only configure the subset of parameters related to runtime-configurable
controls, and won't be allowed to sleep when doing so.
Because partial reconfiguration can depend on parameters computed when
performing a full configuration, the core guarantees that the configure
operation will always be called with full and partial modes in that
order at stream start. Entities thus don't have to duplicate
configuration steps in the full and partial code paths.
This change affects the VSP driver core only, all entities return
immediately from the configure operation when called for a partial
runtime configuration. Entities will be modified one by one in further
commits.

Freeing a fragment requires freeing DMA coherent memory, which can be
performed with interrupts disabled as per the DMA mapping API contract.
The fragments can't thus be freed synchronously when a display list is

The LIF is only used when feeding the VSP output to the DU. The only way
to do so is by controlling the VSP directly from the DU driver and

The device is stopped when STREAMOFF is called on the last video node in
the pipeline. This results in possible memory corruption and/or crashes,
as userspace could free buffers while the hardware is still writing to
them, and the frame completion interrupt handler could try to access
buffers that don't exist anymore.
Fix this by stopping the pipeline upon the first STREAMOFF call, not the
last.

The vsp1_pipeline_reset() function loops over pipeline inputs and output
and resets them. When doing so it assumes both that the pipeline has
been correctly configured with an output, and that inputs are are stored
in the pipe inputs array at positions 0 to num_inputs-1.
Both the assumptions are incorrect. The pipeline might need to be reset
after a failed attempts to configure it, without any output specified.
Furthermore, inputs are stored in a positiong equal to their RPF index,
possibly creating holes in the inputs array if the RPFs are not used in
sequence.
Fix both issues by looping over the whole inputs array and skipping
unused entries, and ignoring the output when not set.

The power_on function of the driver resets the chip and sets the
CHIP_CONTROL register to 0. This switches the operating mode to slave.
The s_stream function sets the correct mode. But this caused problems on
a board where the camera chip is operated as master. The camera started
after a random amount of time streaming an image, I observed between 10
and 300 seconds.
The STRFM_OUT and STLN_OUT pins are not connected on this board which
may cause some issues in slave mode. I could not find any documentation
about this.
Keeping the chip in master mode after the reset helped to fix this
