[PATCH 0/6] drm/vc4: VEC (SDTV) output support

Here's a series from Boris for enabling SDTV output on VC4.  There are
two other patches to the clk subsystem necessary to get it working,
which I'm in the process of reviewing.

I've tested it on composite input of a monitor I had laying around,
and it's basically working.  Booting with the firmware bringing up
SDTV, I get an image "fine" (to the extent that SDTV is ever fine).
If I boot with firmware bringing up HDMI and switch to VEC later, then
the image is gray, but the clock got set to 106Mhz instead of 108 so
this is probably not a DRM bug.

This series was entirely written by Boris, but I've got the permission
to send it out so it's being routed through me.

Boris Brezillon (6):
  drm/vc4: Fix ->clock_select setting for the VEC encoder
  drm: Add TV connector states to drm_connector_state
  drm/vc4: Add support for the VEC (Video Encoder) IP
  drm/vc4: Document VEC DT binding
  ARM: bcm/dt: Add VEC node in bcm283x.dtsi
  ARM: bcm/dt: Enable the VEC IP on all RaspberryPi boards
