* - height: height of the frame in number of lines.
* - ch_id: channel ID.
* - fmt_type: format type.
* - hblank_cycles: length of horizontal blanking in cycles.
* - marker_cycles: number of empty cycles after start-of-line and before
* end-of-frame.
* - two_ppc: boolean, describes whether to send one or two pixels per clock
* cycle. In this mode, we sent pixels N and N+1 in the same cycle,
* to IF_PRIM_A and IF_PRIM_B respectively. The caller must make
* sure the input data has been formatted correctly for this.
* For example, for RGB formats this means that unused values
* must be inserted.
* - yuv420: boolean, describes whether (non-legacy) yuv420 data is used. In
* this mode, the odd lines (1,3,5 etc) are half as long as the
* even lines (2,4,6 etc).
* Note that the first line is odd (1) and the second line is even
* (2).
*
* This function does not do any reordering of pixels, the caller must make
* sure the data is in the righ format. Please refer to the CSS receiver
* documentation for details on the data formats.
