I added support for the Onkyo SE-300PCIE (OK0010), a Creative X-Fi
CA20K2-based sound card with dual TI PCM1798 DACs, a single TI PCM1681
DAC for 7.1ch output, and a CS5364 ADC. This model differs
significantly from other CA20K2-based variants.

Since official driver support for this hardware was discontinued a long
time ago, this patch series enables the card to be used on modern
platforms.

This patch series was developed using QEMU vfio tracing, and PCIe BAR
dumps. Tested with analog output (up to 192kHz) and line/microphone
input (up to 96kHz) at various sample rates.

Harin Lee (6):
  ALSA: ctxfi: Add hw parameter to daio_mgr_dao_init()
  ALSA: ctxfi: Add ADC helper functions for GPIO
  ALSA: ctxfi: Use explicit output flag for DAIO resources
  ALSA: ctxfi: Refactor resource alloc for sparse mappings
  ALSA: ctxfi: Add support for dedicated RCA switching
  ALSA: ctxfi: Add support for Onkyo SE-300PCIE (OK0010)
