From 8382f480bccb1a065e28c1c7676149c2b9a5d2f6 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 31 Aug 2016 10:56:48 -0300 Subject: ARM: dts: imx6qdl: Fix SPDIF regression Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") changed many more clocks than only the SPDIF core clock as stated in the commit message. The MLB clock has been added and this causes SPDIF regression as reported by Xavi Drudis Ferran and also in this forum post: https://forum.digikey.com/thread/34240 The MX6Q Reference Manual does not mention that MLB is a clock related to SPDIF, so change it back to a dummy clock to restore SPDIF functionality. Thanks to Ambika for providing the fix at: https://community.nxp.com/thread/387131 Fixes: 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") Cc: # 4.4.x Reported-by: Xavi Drudis Ferran Signed-off-by: Fabio Estevam Tested-by: Xavi Drudis Ferran Signed-off-by: Shawn Guo (cherry picked from commit f065e9e4addd75c21bb976bb2558648bf4f61de6) Tested playback and record on pulseaudio with 44.1kHz samples.
