[PATCH 09/15] media: stm32: dcmipp: add 1X16 RGB / YUV formats support

From: Alain Volmat
Date: Tue Oct 08 2024 - 07:24:41 EST


Add 1X16 RGB & YUV formats support within bytecap & byteproc.
Slightly change the link_validate function to be able to validate
against either 1X16 or 2X8 variant of a format.
