| 31 | * Thanks to David Pollard for testing. |
| 32 | * |
| 33 | * Changes: |
| 34 | * 20000909-nf Changed cs_read, cs_write and drain_dac |
| 35 | * 20001025-tw Separate Playback/Capture structs and buffers. |
| 36 | * Added Scatter/Gather support for Playback. |
| 37 | * Added Capture. |
| 38 | * 20001027-nf Port to kernel 2.4.0-test9, some clean-ups |
| 39 | * Start of powermanagement support (CS46XX_PM). |
| 40 | * 20001128-tw Add module parm for default buffer order. |
| 41 | * added DMA_GFP flag to kmalloc dma buffer allocs. |
| 42 | * backfill silence to eliminate stuttering on |
| 43 | * underruns. |
| 44 | * 20001201-tw add resyncing of swptr on underruns. |
| 45 | * 20001205-tw-nf fixed GETOSPACE ioctl() after open() |
| 46 | * 20010113-tw patch from Hans Grobler general cleanup. |
| 47 | * 20010117-tw 2.4.0 pci cleanup, wrapper code for 2.2.16-2.4.0 |
| 48 | * 20010118-tw basic PM support for 2.2.16+ and 2.4.0/2.4.2. |
| 49 | * 20010228-dh patch from David Huggins - cs_update_ptr recursion. |
| 50 | * 20010409-tw add hercules game theatre XP amp code. |
| 51 | * 20010420-tw cleanup powerdown/up code. |
| 52 | * 20010521-tw eliminate pops, and fixes for powerdown. |
| 53 | * 20010525-tw added fixes for thinkpads with powerdown logic. |
| 54 | * 20010723-sh patch from Horms (Simon Horman) - |
| 55 | * SOUND_PCM_READ_BITS returns bits as set in driver |
| 56 | * rather than a logical or of the possible values. |
| 57 | * Various ioctls handle the case where the device |
| 58 | * is open for reading or writing but not both better. |
| 59 | * |
| 60 | * Status: |
| 61 | * Playback/Capture supported from 8k-48k. |
| 62 | * 16Bit Signed LE & 8Bit Unsigned, with Mono or Stereo supported. |
| 63 | * |
| 64 | * APM/PM - 2.2.x APM is enabled and functioning fine. APM can also |
| 65 | * be enabled for 2.4.x by modifying the CS46XX_ACPI_SUPPORT macro |
| 66 | * definition. |
| 67 | * |
| 68 | * Hercules Game Theatre XP - the EGPIO2 pin controls the external Amp, |
| 69 | * so, use the drain/polarity to enable. |
| 70 | * hercules_egpio_disable set to 1, will force a 0 to EGPIODR. |
| 71 | * |
| 72 | * VTB Santa Cruz - the GPIO7/GPIO8 on the Secondary Codec control |
| 73 | * the external amplifier for the "back" speakers, since we do not |
| 74 | * support the secondary codec then this external amp is also not |
| 75 | * turned on. |
