Re: [PATCH 05/12] drm: bridge/dw_hdmi: add support for interlaced video modes

Add support for interlaced video modes to the dw_hdmi bridge. This mainly involves halving the vertical parameters to be programmed into the bridge registers, and setting the interlace_allowed connector flag.

This brings working 1080i support. However, 480i and 576i fail to work due to the lack of proper pixel repetition support, which is not trivial to add due to the tabular PLL parameterisation. Hence, we filter out these modes in our mode_valid() method.
