Neusch=C3=A4fer" 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). For reasons of compatibility with historical device trees and readability of the unit addresses, this format is kept. Relax the $nodename pattern in raw-nand-chip.yaml to allow such unit addresses. Unfortunately $nonenames defined in bindings that reference raw-nand Reviewed-by: Rob Herring (Arm) Signed-off-by: J.
