Message-ID <[email protected]>
This series adds a V4L2 capture driver for the Axiado AX3000/AX3005
display capture path and its Device Tree binding.

  [1/2] dt-bindings: media: add axiado,ax3000-video
  [2/2] media: axiado: add V4L2 capture driver for AX3000/AX3005 SoC

There is no local register interface for this driver to program.
Frame delivery is controlled entirely by the host-side display engine
and the PCIe endpoint mapping, both external to this driver; on the
AX3000/AX3005 side this is a passive memory window that gets read on
a timer. The AX300X operates as a PCIe endpoint BMC. Neither the PCIe
endpoint driver nor the host-side display driver are upstream yet;
both are planned as follow-on series.

Tested on AX3005 hardware using v4l2-ctl (format enumeration, S_FMT,
REQBUFS, streaming) and obmc-ikvm for end-to-end capture verification.
dt_binding_check passes.
