Hi Bjorn,
I couldn't get one 8974 device. I tested the latest linux-next on db410c
and its not showing any issue. 8974 is an older msm and has some
differences in the controller like your "mmc: sdhci-msm: Enable delay
circuit calibration clocks" patch.
I am currently going through the programming guide to see what could be
the reason. Can you please share the full logs from the device with me
so that I can focus my search?
Thanks,
Vijay
