Dear All,

I've been working on a kernel patch for a firmware IRQ quirk issue that 
affects multiple Intel Atom Bay-Trail boards:

https://bugzilla.kernel.org/show_bug.cgi?id=117141

If you have a Bay Trail device with non-functioning sound, can you 
attach the DSDT and dmidecode output to the bug so I can investigate 
whether the quirk affect your device.

Best Regards
Joel Holdsworth

The IRQ fix is not enough to get sound on Baytrail-CR devices. You need 
to also swap SSP2 with SSP0 due to a package change, which is not 
supported with the 'older' byt-rt5640 driver so that's a dead-end - 
sorry. There are Intel patching coming for the bytcr-rt5640 to model all 
the possible routing and quirks, stay tuned.
