Subject: ARM: dts: imx6qdl: Fix SPDIF regression
From: Fabio Estevam <fabio.estevam@xxxxxxx>
commit f065e9e4addd75c21bb976bb2558648bf4f61de6 upstream.
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:
