- * Thanks to David Pollard for testing.
- *
- * Changes:
- * 20000909-nf Changed cs_read, cs_write and drain_dac
- * 20001025-tw Separate Playback/Capture structs and buffers.
- * Added Scatter/Gather support for Playback.
- * Added Capture.
- * 20001027-nf Port to kernel 2.4.0-test9, some clean-ups
- * Start of powermanagement support (CS46XX_PM).
- * 20001128-tw Add module parm for default buffer order.
- * added DMA_GFP flag to kmalloc dma buffer allocs.
- * backfill silence to eliminate stuttering on
- * underruns.
- * 20001201-tw add resyncing of swptr on underruns.
- * 20001205-tw-nf fixed GETOSPACE ioctl() after open()
- * 20010113-tw patch from Hans Grobler general cleanup.
- * 20010117-tw 2.4.0 pci cleanup, wrapper code for 2.2.16-2.4.0
- * 20010118-tw basic PM support for 2.2.16+ and 2.4.0/2.4.2.
- * 20010228-dh patch from David Huggins - cs_update_ptr recursion.
- * 20010409-tw add hercules game theatre XP amp code.
- * 20010420-tw cleanup powerdown/up code.
- * 20010521-tw eliminate pops, and fixes for powerdown.
- * 20010525-tw added fixes for thinkpads with powerdown logic.
- * 20010723-sh patch from Horms (Simon Horman) -
- * SOUND_PCM_READ_BITS returns bits as set in driver
- * rather than a logical or of the possible values.
- * Various ioctls handle the case where the device
- * is open for reading or writing but not both better.
- *
- * Status:
- * Playback/Capture supported from 8k-48k.
- * 16Bit Signed LE & 8Bit Unsigned, with Mono or Stereo supported.
- *
- * APM/PM - 2.2.x APM is enabled and functioning fine. APM can also
- * be enabled for 2.4.x by modifying the CS46XX_ACPI_SUPPORT macro
- * definition.
- *
- * Hercules Game Theatre XP - the EGPIO2 pin controls the external Amp,
- * so, use the drain/polarity to enable.
- * hercules_egpio_disable set to 1, will force a 0 to EGPIODR.
- *
- * VTB Santa Cruz - the GPIO7/GPIO8 on the Secondary Codec control
- * the external amplifier for the "back" speakers, since we do not
- * support the secondary codec then this external amp is also not
- * turned on.
