Bayer bit justification

Synopsis:

#include <camera/camera_api.h>

typedef enum {
    CAMERA_BAYERJUSTIFY_RIGHT_BIT0LSB,
    CAMERA_BAYERJUSTIFY_LEFT_BIT0LSB,
    CAMERA_BAYERJUSTIFY_RIGHT_BIT0MSB,
    CAMERA_BAYERJUSTIFY_LEFT_BIT0MSB
} camera_bayerjustify_t;

Data:

CAMERA_BAYERJUSTIFY_RIGHT_BIT0LSB: Bit 0 is the least significant bit, and the bits are right justified.
CAMERA_BAYERJUSTIFY_LEFT_BIT0LSB: Bit 0 is the least significant bit, and the bits are left justified.
CAMERA_BAYERJUSTIFY_RIGHT_BIT0MSB: Bit 0 is the most significant bit, and the bits are right justified.
CAMERA_BAYERJUSTIFY_LEFT_BIT0MSB: Bit 0 is the most significant bit, and the bits are left justified.

Description:

The Bayer bit justification indicates whether bit 0 is the least significant or most significant bit of the word, and it also indicates whether the bits are justified towards the 0th bit (right justified), or to the Nth bit (left justified). For example:

le = false
bpp = 10
packing = 16
cadence_length = 16
pixels_per_cadence = 1
format = CAMERA_BAYERFORMAT_RGGB

CAMERA_BAYERJUSTIFY_RIGHT_BIT0LSB would represent:

Bit:          FEDCBA9876543210 FEDCBA9876543210
Scanline n:   000000RRRRRRRRRR 000000GGGGGGGGGG
Scanline n+1: 000000GGGGGGGGGG 000000BBBBBBBBBB

Note that the 0th bit in the word represents the least-significant bit, and the bits are justified to the right of the word.
