[v1] ALSA: add suspend/resume support for InterWave ISA cards

[PATCH 0/3] ALSA: add suspend/resume support for InterWave ISA cards

Posted by Cássio Gabriel 2 months, 1 week ago

This 3-patch series wires up suspend and resume support for the
InterWave ISA drivers and their PnP front-end around the shared
GUS PM helpers.

The first patch moves the remaining standalone
snd_tea6330t_detect() EXPORT_SYMBOL() declaration next to its
function definition as a requested small cleanup.

The second patch adds a small TEA6330T helper so the InterWave STB
variant can restore its cached external mixer state after resume.

The third patch adds ISA and PnP PM callbacks to snd-interwave and
restores the remaining InterWave-specific state that the generic GUS
resume path does not cover, including the GF1 board registers and the
detected memory layout.

The resume path intentionally does not rerun probe-time DRAM/ROM
detection. As with the shared GUS PM support, this does not guarantee
preservation of sample RAM contents across suspend.

Please, disregard this patch series.
I do not change the header to be [PATCH V2].
I'll resend it correctly this time.
