Which is OK only because sdhci-msm is the only caller of cqhci_pltfm_init(),
right?  So no one else could be using "cqhci_mem"? Some more explanation is
needed here.

Right, only qcom cqhci solution is making use of it.

I did a grep in dt and find no other vendor is using it.

Sure. Will update commit text.

[PATCH V2] mmc: cqhci: Update cqhci memory ioresource name

[Veerabhadrarao Badiganti]

Update cqhci memory ioresource name from cqhci_mem to cqhci since
suffix _mem is redundant.

Only sdhci-msm driver is making use of this resource as of now.
No other vendor's driver is using it. So this update shouldn't affect
any other vendor's cqhci functionality.

I do favor using names without the "_mem" suffix and it seems like the
existing code only acquire the first two regions by index. So this
should be fine.

Acked-by: Bjorn Andersson <bjorn.andersson@linaro.org>


But I do expect to see some patches fixing up the 8 dts files that now
has invalid reg-names.

Bjorn
