* <nils@kernelconcepts.de>
|
|
* 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.
