[alsa-devel] Adding wm8962 support to mx6qsabresd
Hi,
I am working on adding audio support to mx6qsabresd board, which contains a wm8962 codec.
Here is the log with debug information turned on that I am getting so far:

Without seeing your code or knowing which kernel version you're running it's a bit hard to comment...
wm8962 0-001a: wm8962->lrclk = 44100 wm8962 0-001a: Selected sysclk ratio 256 wm8962 0-001a: read 4 => ffffffff wm8962 0-001a: Failed to read DSPCLK: -1
This suggests that physical I/O to the device isn't working. Is it clocked and powered?
wm8962 0-001a: read 3 => 100 wm8962 0-001a: write 3 = 100 wm8962 0-001a: ASoC: POST_PMU: HPOUTR PGA event failed: -5
You've not enabled any of the debug in the driver... it might give you some hints.
Fabio,
FSL internal development team has got it work on kernel 3.5. You can talk to Gary (Cc-ed) for details and upstreaming plan.
