drm/fsl-dcu: use mode flags for hsync/vsync polarity
The current default configuration is as follows:
- Invert VSYNC signal (active LOW)
- Invert HSYNC signal (active LOW)
The mode flags allow to specify the required polarity per
mode. Furthermore, none of the current driver settings is
actually a standard polarity.
This patch applies the current driver default polarities as
explicit flags to the display which has been introduced with
the driver (NEC WQVGA "nec,nl4827hc19-05b"). The driver now
also parses the flags field and applies the configuration
accordingly, by using the following values as standard
polarities: (e.g. when no flags are specified):
- VSYNC signal not inverted (active HIGH)
- HSYNC signal not inverted (active HIGH)

The ODDF signal, output by default on the ODDF pin, isn't used on any

drm: rcar-du: Add VSP1 support to the planes allocator

maximum availability of planes 0 and 1.
Rename plane setup functions using more explicit names, and use local

A disabled CRTC can't display planes, the driver shouldn't try to
configure it when updating planes. The DRM core will store the plane

[media] v4l: vsp1: Configure device based on IP version
The IP version number carries enough information to identify the exact
device instance features. Drop the related DT properties and use the IP
version instead.
Display lists contain lists of registers and associated values to be
applied atomically by the hardware. They lower the pressure on interrupt
processing delays when reprogramming the device as settings can be
prepared well in advance and queued to the hardware without waiting for
the end of the current frame.
Display list support is currently limited to the DRM pipeline.
[media] v4l: vsp1: Implement atomic update for the DRM driver
Add two API functions named vsp1_du_atomic_begin() and
vsp1_du_atomic_flush() to signal the start and end of an atomic update.
The vsp1_du_setup_rpf() function is renamed to vsp1_du_atomic_update()
for consistency.
With this new API, the driver will reprogram all modified inputs
atomically before restarting the video stream.
Implement internal control of the VSP pipeline to be used by the DU
DRM/KMS driver when using the VSP as an internal composer handled
through DRM/KMS only.
[media] v4l: vsp1: Don't validate links when the userspace API is disabled
As the pipeline is configured internally by the driver when the
userspace API is disabled its configuration can be trusted and link
validation isn't needed.
[media] v4l: vsp1: Set the alpha value manually in RPF and WPF s_stream handlers
The RPF and WPF alpha values are set through V4L2 controls and applied
when starting the video stream by a call to v4l2_ctrl_handler_setup().
As that function uses the control handler mutex it can't be called in
interrupt context, where the VSP+DU pipeline handler might need to
reconfigure the pipeline.
Set the alpha value manually in the RPF and WPF s_stream handler to
ensure that the hardware is properly configured even when controlled
without the userspace API. If the userspace API is enabled protect that
with the control lock to avoid race conditions with userspace.
[media] v4l: vsp1: Make pipeline inputs array index by RPF index
The pipeline inputs array stores pointers to all RPFs contained in the
pipeline. It's currently indexed contiguously by adding RPFs in the
order they are found during graph walk. This can't easily support
dynamic addition and removal of RPFs while streaming, which will be
required for combined VSP+DU support.
Make the array indexed by RPF index instead and skip NULL elements when
iterating over RPFs.
[media] v4l: vsp1: Make the userspace API optional
