From b91ab72b830e1494c2c7f8de05ccb2ab2c9cfb26 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Tue, 1 Sep 2009 08:23:58 +0200 Subject: sound: oxygen: fix MCLK rate for 192 kHz playback Do not forget to program the MCLK ratio for the I2S output. Otherwise, the master clock frequency can be too high for the DACs at sample frequencies above 96 kHz.

In this case, we have to use the default ID to allow the driver to load.
