Wouldn't 'nand-controller' be appropriate? Actually I've added this pattern here because there are several users in the arm/boot/dts/ directory which use it, and the example below in this file also uses onenand@xxx. I can either fix the example to use nand-controller or add this pattern (I guess "deprecated: true" would not mean anything?). What do you prefer? If we decide to switch to the nand-controller@ name, shall I change the DTS as well? Thanks, Miquèl

The chip node name in this driver is expected to be different and should be prefixed with onenand instead of the regular "flash" string, so mention it.
