Hello,
this series add support for 'digital' input to the Gen3 version of rcar-vin
driver.
'Digital' inputs (the terms comes from the existing Gen2 version of the driver)
describe parallel video input sources connected to a VIN instance. So far, the
Gen3-version of the driver (the media-controller compliant one) only supported
CSI-2 inputs.
This series extends the device tree parsing to accept a connection on port@0,
and parses the 'digital' subdevice reusing the Gen-2 functions.
Compared to v1, this series drops all changes to rcar-dma module, as Niklas
sent a proper fix for both crop and compose rectangle managment and field
signal toggling method. This series is thus based on the media master branch
with Niklas' series on top.
Compared to v1 I incorporated Niklas' suggestion to re-use Gen2 functions for
parsing the digital input device nodes, and register one notifier for each VIN
that has an active connection on port@0. The 'group' notifier then only collects
async subdevices for CSI-2 inputs.
A separate series for the VIN4 and HDMI input enabling on Draak board has been
sent to renesas-soc list.
The vin-tests repository patches to automate capture testing have been extended
to support D3 board and capture from HDMI output, and patches have been sent
to Niklas.
Tested capturing HDMI input images on D3 and for backward compatibility on
Salvator-X M3-W too (seems like I didn't break anything there).
Patches for testing on D3 are available at:
git://jmondi.org/linux d3/media-master/driver-v2
git://jmondi.org/linux d3/media-master/dts
git://jmondi.org/linux d3/media-master/test
git://jmondi.org/vin-tests d3
Patches to test on M3-W (based on latest renesas drivers, which includes an
older version of VIN series, but has CSI-2 driver) available at:
git://jmondi.org/linux d3/renesas-drivers/test
Thanks
