From c308ae532a04877a0f4d1d4e3ea3591e9f9ccf6a Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Mon, 1 Nov 2021 09:15:04 +0000 Subject: libcamera: bayer_format: Rework BayerFormat conversion table Rename the bayerToV4l2 conversion table to bayerToFormat. Update the table to hold both the PixelFormat and V4L2PixelFormat conversions for a given BayerFormat. This will allow converting between BayerFormat and PixelFormat types in a subsequent change.
