The V4L2 API is missing the 16-bit RGB555 formats for the RGBA, RGBX,
ABGR, XBGR, BGRA and BGRX component orders. Add them, using the same
4CCs as DRM.

I see the last 4 formats are identical in their components
disposition. Is this intended?

                   B1                          B0
          b7                   b0   b7                  b0
ABGR555 | g2 g1 g0 b4 b3 b2 b1 b0 | a r4 r3 r2 r1 r0 g4 g3 |
XBGR555 | g2 g1 g0 b4 b3 b2 b1 b0 | x r4 r3 r2 r1 r0 g4 g3 |
BGRA555 | g2 g1 g0 b4 b3 b2 b1 b0 | a r4 r3 r2 r1 r0 g4 g3 |
BGRX555 | g2 g1 g0 b4 b3 b2 b1 b0 | x r4 r3 r2 r1 r0 g4 g3 |

If there is any correlation with the naming scheme (but I think
there's not, at least not a strict one) 'a' and 'x' of BGR* formats
should be in the most significant bit of Byte 1.

Thanks

Unless I'm mistaken, these two are defined in the patch as

  ABGR555 | g2 g1 g0 r4 r3 r2 r1 r0 | a  b4 b3 b2 b1 b0 g4 g3 |
  XBGR555 | g2 g1 g0 r4 r3 r2 r1 r0 | x  b4 b3 b2 b1 b0 g4 g3 |

> BGRX555 | g2 g1 g0 b4 b3 b2 b1 b0 | x r4 r3 r2 r1 r0 g4 g3 |

These two formats are defined as

  BGRA555 | g2 g1 g0 r4 r3 r2 r1 r0 | a  b4 b3 b2 b1 b0 g4 g3 |
  BGRX555 | g2 g1 g0 r4 r3 r2 r1 r0 | x  b4 b3 b2 b1 b0 g4 g3 |

as well, while they should be defined as

  BGRA555 | g1 g0 r4 r3 r2 r1 r0 a  | b4 b3 b2 b1 b0 g4 g3 g2 |
  BGRX555 | g1 g0 r4 r3 r2 r1 r0 x  | b4 b3 b2 b1 b0 g4 g3 g2 |

I will fix this.

Did you mean the least significant bit ?
