Subject: [PATCH v2 12/12] dt-bindings: mtd: raw-nand-chip: Relax node name
 pattern

From: "J. Neuschäfer" <j.ne@...teo.net>

In some scenarios, such as under the Freescale eLBC bus, there are raw
NAND chips with a unit address that has a comma in it (cs,offset).
Relax the $nodename pattern in raw-nand-chip.yaml to allow such unit
addresses.
