I think it's better to parse host specific property in host's driver
rather than the shared sdhci-pltfm.c.
Otherwise, sdhci_get_of_property will become bigger and bigger.
How do you think?
I have submitted below patch aim to do this:
[PATCH 2/2] mmc: sdhci-pltfm: add function in sdhci_ops to parse dt property

Thanks
Kevin
