Yeah, providing some information about what the differences actually are would be good, for the same of the actually-knowledgeable-about-displays folk in the audience (IOW, not me). Probably then the display/atmel/hlcdc-dc.txt binding needs an update too? --vm86L/VjnDury6D6 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZInVfQAKCRB4tDGHoIJi 0t+QAP98ZK1V7j86/YMu7RoLTY1KeXiemdt0SzR3FdJiE/LX5wD8D7rmXmPM2Q2u I+1APY8ZTJDKVahjB3NLEdDAi3STkA4= =HLvp -----END PGP SIGNATURE----- --vm86L/VjnDury6D6-- --===============3878554374027600878== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============3878554374027600878==--
