2022-05-17media: v4l2: Reorder field reflistNicolas Dufresne1-0/+42
As per spec, the field reflist requires interleaving top and bottom field in a specific way that does not fit inside the sort operation. The process consist of alternating references parity, starting with a reference of the same parity as the current picture. This processs is done twice, once for short term references and a second time for the long term references.

2022-05-17media: h264: Sort p/b reflist using frame_numNicolas Dufresne2-12/+13
In the reference list builder, frame_num refers to FrameNumWrap in the spec, which is the same as the pic_num for frame decoding. The same applies for long_term_pic_num and long_term_frame_idx. Sort all type of references by frame_num so the sort can be reused for fields reflist were the sorting is done using frame_num instead. In short, pic_num is never actually used for building reference lists.

The imx412/imx577 sensor has a reset line that is active low not active high. Currently the logic for this is inverted. The right way to define the reset line is to declare it active low in the DTS and invert the logic currently contained in the driver. The DTS should represent the hardware does i.e. reset is active low. So: + reset-gpios = <&tlmm 78 GPIO_ACTIVE_LOW>; not: - reset-gpios = <&tlmm 78 GPIO_ACTIVE_HIGH>; I was a bit reticent about changing this logic since I thought it might negatively impact @intel.com users.
