    sys/dev/sound/pci    es137x.c es137x.h 
  Log:
  * Register programming error during device initialization
    especially for CT4730 / EV1938 chip, causing misconfigured mixer
    (David Xu), crippled after power cycle (Kevin Oberman). Fixed.
  * Incorporate locking/spdif patches from Jon Noack / matk. Not all
    es137x can really do spdif, clean it up a bit to only let few capable
    chip. This adds a "hw.snd.pcm<unit>.spdif_enabled" sysctl until
    a more generic way of handling this from userland (by an ordinary
    user) is designed/implemented.
  * Convert all bus_space_(read|write) to use es_rd/es_wr, simmilar
    with other drivers.
  * Add tunable hw.snd.pcm<unit>.latency_timer sysctl to toggle pci
    latency timer value on the fly. Much noise / pop / crackling
    issues can be solved by increasing its value. Other people have
    pointed out to use pciconf instead, but this is just an added
    value specific for CT4730/EV1938.
  * Remove es137x specific debug sysctl/code.
  
  Several PRs can now be closed.
