Subject: ARM: dts: imx6: remove wrong spdif rxtx2 clock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=36cc5c13d92d9372f3c3c549b8fe200a646ee53c;p=karo-tx-linux.git

ARM: dts: imx6: remove wrong spdif rxtx2 clock

The rxtx2 clock of i.MX6 S/PDIF is currently set to "asrc" clock.
However, according to SoC documentation, rxtx2 is connected to
ASRC_EXT_CLK, a different external clock.

Testing on Cubox-i system seems to confirm that: when fsl_spdif is
forced to select rxtx2 as input clock, audio playback fails with an I/O
error.

Set rxtx2 to the dummy clock by default to prevent fsl_spdif from
selecting it.
