Agree, as I think it's probably not only Baytrail that suffer from this. Although it seems like some Baytrail developer need to take a lead on this. Regarding patch[2], in general it seems like the correct approach (although perhaps not applied to generic sdhci code, but in sdhci variants). In some case the SoC/mmc-controller can support a different wakeup setting that doesn't require the clock to be ungated to wakeup on SDIO irq... > > I can help with testing. That's great, thanks for volunteering!
