Hello,
with commit c9711ec5250b22fd94e9b34c17c095e001a90e66
("mtd: nand: omap: Clean up device tree support")
the old "elm_id" property check has been removed. So only "ti,elm-id" is
valid now.
I noticed that the old property is still used by 3 boards:
git grep elm_id arch/arm/boot/dts/*
arch/arm/boot/dts/am335x-baltos.dtsi: elm_id = <&elm>;
arch/arm/boot/dts/am335x-igep0033.dtsi: elm_id = <&elm>;
arch/arm/boot/dts/am335x-phycore-som.dtsi: elm_id = <&elm>;
I wonder if the right way would be to patch the device trees, or to add
the check again and to keep backward compatibility?
I may provide a patch then.
Regards,
Teresa

We should probably do both, though backward compat is usually dependent
on the platform maintainer (some accept to break DT backward compat).
Anyway, all DTs should be patched to use the new binding, so you can at
least send a patch doing that.
