Hi Artem,
Today's linux-next merge of the l2-mtd tree got a conflict in
Documentation/devicetree/bindings/arm/davinci/nand.txt between commit
fed16bba8726 ("mtd: nand: davinci: fix the binding documentation") from
Linus' tree and commit 192afdbfbc5c ("mtd: davinci: add support for
parition binding nodes") from the l2-mtd tree.
I fixed it up (maybe- see below) and can carry the fix as necessary (no
action is required).

partition@180000 is sub-node of nand_cs3@62000000.
nand_cs3@62000000 needs to use below properties
#address-cells =<1>;
#size-cells =<1>;
Without these properties DT build will give reg format Warning.

Anul,
Could you point me to a corresponding driver commit id?
