[alsa-devel] [PATCH v2 3/4]: ALSA: oxygen: Move the Xonar DG mixer code away from this file and actual driver changes
Roman Volkov

Thu Nov 21 16:28:48 CET 2013
Move the mixer controls and other system structures to a separate file. Also there are actual driver changes: Multichannel routing, CS4245 initialization, CS4245 SPI reading and writing, DAC/ADC settings, suspend/resume logic.
Signed-off-by: Roman I. Volkov <v1ron at mail.ru>
---
I can confirm, the driver also works with OXYGEN_FUNCTION_ENABLE_SPI_4_5 removed.
