We've now seen the same bug on at least MSM, Arasan, and Intel hardware. ]] SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't tracking that properly in software. When out of sync, we may trigger various timeouts. It's not typical to perform resets while CQE is enabled, but this may occur in some suspend or error recovery scenarios. Include this fix by way of the new sdhci_and_cqhci_reset() helper. I only patch the bcm7216 variant even though others potentially *could* provide the 'supports-cqe' property (and thus enable CQHCI), because d46ba2d17f90 ("mmc: sdhci-brcmstb: Add support for Command Queuing (CQE)") and some Broadcom folks confirm that only the 7216 variant actually supports it. This patch depends on (and should not compile without) the patch entitled "mmc: cqhci: Provide helper for resetting both SDHCI and CQHCI".
