From ca8c7f233fa2c40e2a23f982dc33d947f28ad207 Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Tue, 6 Dec 2016 20:22:37 +0100 Subject: ASoC: atmel: tse850: rely on the ssc to register as a cpu dai by itself This breaks devicetree compatibility, but in this case that is ok. All affected units are either on my desk, or running an even older version of the driver that is not compatible with the upstreamed version anyway (and when these other units are eventually updated, they will get a fresh dtb as well, so that is not a significant problem either). All of that is of course assuming that noone else has managed to build something that can use this driver, but that seems extremely improbable.
