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.
