I wonder if this should really be documented for sdhci instead of ti-omap-hsmmc.txt? I agree it's better to use sdhci compatible and keep the hsmmc compatible around as the sdhci is still missing features for runtime PM and context save and restore etc. Regards, Tony > Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> > --- > Documentation/devicetree/bindings/mmc/ti-omap-hsmmc.txt | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/Documentation/devicetree/bindings/mmc/ti-omap-hsmmc.txt b/Documentation/devicetree/bindings/mmc/ti-omap-hsmmc.txt > index 0e026c151c1c..db80fdfd05d7 100644 > --- a/Documentation/devicetree/bindings/mmc/ti-omap-hsmmc.txt > +++ b/Documentation/devicetree/bindings/mmc/ti-omap-hsmmc.txt > @@ -13,6 +13,7 @@ Required properties: > Should be "ti,omap3-pre-es3-hsmmc" for OMAP3 controllers pre ES3.0 > Should be "ti,omap4-hsmmc", for OMAP4 controllers > Should be "ti,am33xx-hsmmc", for AM335x controllers > + Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers > - ti,hwmods: Must be "mmc<n>", n is controller instance starting 1 > > Optional properties: > -- > 2.11.0 > -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

But we'll be never able to remove omap-hsmmc driver then and end up maintaining 2 drivers for the same controller. > > I agree it's better to use sdhci compatible and keep the > hsmmc compatible around as the sdhci is still missing features > for runtime PM and context save and restore etc. yeah, once we have all the features in omap_hsmmc added in sdhci-omap, we can add the omap-hsmmc compatible to sdhci-omap and remove omap-hsmmc driver.

Well I think it's best to be able to enable sdhci one board at a time after testing. Then eventually when fully supported, we can just have sdhci also parse the legacy omap binding and just drop the omap-hsmmc driver.
