| Subject: sound: oxygen: fix MCLK rate for 192 kHz playback |
| |
| From: Clemens Ladisch <clemens@ladisch.de> |
| |
| commit b91ab72b830e1494c2c7f8de05ccb2ab2c9cfb26 upstream. |
| |
| 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. |
