Yer breakin' mah build!
The second register here (and probably all boards) needs to be
"cqhci". See the line in the driver that looks like:
/* check and setup CMDQ interface */
cqhci_memres = platform_get_resource_byname(pdev, IORESOURCE_MEM,
"cqhci");
For history, see commit d3392339cae9 ("mmc: cqhci: Update cqhci memory
ioresource name") and commit d79100c91ae5 ("dt-bindings: mmc:
sdhci-msm: Add CQE reg map").
The problem here is not the device trees but the yaml. When you
convert from .txt to .yaml you're not allowed to just rewrite the
binding. It should also be noted that the "_mem" suffix was explicitly
requested to be removed.
