[PATCH v3 6/9] v4l: xilinx: dma: Update video format descriptor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch updates video format descriptor to help information
viz., number of planes per color format and chroma sub sampling
factors.

This commit adds the various 8-bit and 10-bit that are supported
to the table queried by drivers.
