Pyun YongHyeon 7a7386a3e2 Device driver for onboard CS4231 audio controller which is found ... on UltraSPARC workstations. The driver is based on OpenBSD's SBus cs4231 driver and heavily modified to incorporate into sound(4) infrastructure. Due to the lack of APCDMA documentation, the DMA code of SBus cs4231 came from OpenBSD's driver. The driver runs without Giant lock and supports both SBus and EBus based CS4231 audio controller. Special thanks to marius for providing feedbacks during the driver writing. His feedback made it possible to write hiccup free playback code under high system loads.
