template <, >Endianness endianness_128_bit ()Byte ordering ("endianness") for every 128-bit (16-byte) chunk.
This bit is not documented in any datasheet. Experiments on Khadas
VIM3 (A311D), Astro (S905D2) and Nelson (S905D3) all confirm that
this bit is available and functions as described above for both VDINs.

above for both VDINs.

template <, >typename SelfType::ValueType left_px_inclusive ()The leftmost column (inclusive) to write on the write image buffer, in
pixels.
Must be less than or equal to `right_px_inclusive`.
The Amlogic datasheets specify that this field uses bits 28-16 for VDIN0
bits 27-16 for VDIN1. However, both the "Display Write Back App-Note"
and experiments on Khadas VIM3 (A311D) confirm that it actually uses
bits 28-16 for both VDINs.
It's preferred to use the `SetHorizontalRange()` helper method.

VideoInputWriteRangeHorizontal & SetHorizontalRange (int left_px_inclusive, int right_px_inclusive)Sets the horizontal range of the write image buffer to
`[left_px_inclusive, right_px_inclusive]`.
`left_px_inclusive` must be less than or equal to `right_px_inclusive`.
Both `left_px_inclusive` and `right_px_inclusive` must be non-negative and
less than 2^13 (8192).
