Subject: drm/atmel-hlcdc: set layer REP bit to enable replication logic
Git-commit: e3c91a88e4f265a5ec58f6e3be0880255156f600
Patch-mainline: v5.4-rc1
References: bsc#1152472
This bit enables replication logic to expand an RGB color less than 24
bits, to 24 bits, which is used internally for all formats. Otherwise,
the least significant bits are always set to zero and the color may not
be what is expected.
