# 1.2 09-Feb-2001 aaron

branches: 1.2.4;
Tickle D0 power state so the cs4281 works after reboots from Windows 2000.
From NetBSD, tested on a dual-boot IBM ThinkPad X20.
# 1.1 13-Jan-2001 aaron

Driver for Cirrus Logic CS4281 sound chips. Originally written for NetBSD by
Tatoku Ogaito, banged into shape for OpenBSD by me. Recording has not been
tested yet, but mpg123 works fine. Sound still works after suspend/resume.

XXX: On the IBM ThinkPad X20, must disable pcibios else the cs4281 won't
generate interrupts. Cause yet unknown but probably not the driver's fault.
YMMV on other laptops with this chip.
