I thought I already discouraged extending this binding to be generic. Particularly, we do *not* want to codify things like 'linux,part-probe = "bcm47xxpart"', which doesn't follow any accepted practice about naming. And you've also failed to document any actual strings to put here, which hides the fact that you're opening a can of worms. Piece of a previous thread: http://lists.infradead.org/pipermail/linux-mtd/2015-October/062613.html [PATCH] mtd: document linux-specific partition parser DT binding I attempted to resolve that here, but never made time to address the few not-so-constructive comments I received: https://mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg1035539.html [RFC PATCH 0/7] mtd: partitions: add of_match_table support I'd still prefer that approach to supporting this shortcut for all MTDs.
