+Subject: [PATCH] Revert "Support compressed pixel formats when saving DNGs"
+
+This reverts commit a85aed7603a0b69a6685d3f81ee860246d5b1621.
+
+This requires rpi specific fork of libcamera to provide e.g.
+formats::RGGB16_PISP_COMP1
+added in:
+https://github.com/raspberrypi/libcamera/commit/fb3cb844f2117f30d3eeece99d6ce4d02624e492
+but not included in libcamera from meta-oe:
+https://git.openembedded.org/meta-openembedded/commit/?id=711c6fbce39df685225bca081c5f42bae2de658b
