Update cadence-nand-controller.txt to cdns,hp-nfc.yaml in MAINTAINER file. Signed-off-by: Niravkumar L Rabara --- Changes in v3: - Changed file name to cdns,hp-nfc.yaml to match with compatible. - Update description, fixed alignment, and used defines for interrupt flag as per review comments in v2. Changes in v2: - Update name cadence-nand-controller.txt to cadence,nand.yaml in MAINTAINER file to resolve the warning. .../bindings/mtd/cadence-nand-controller.txt | 53 ------------- .../devicetree/bindings/mtd/cdns,hp-nfc.yaml | 75 +++++++++++++++++++ MAINTAINERS | 2 +- 3 files changed, 76 insertions(+), 54 deletions(-) delete mode 100644 Documentation/devicetree/bindings/mtd/cadence-nand-controller.txt create mode 100644 Documentation/devicetree/bindings/mtd/cdns,hp-nfc.yaml diff --git a/Documentation/devicetree/bindings/mtd/cadence-nand-controller.txt b/Documentation/devicetree/bindings/mtd/cadence-nand-controller.txt deleted file mode 100644 index d2eada5044b2..000000000000 --- a/Documentation/devicetree/bindings/mtd/cadence-nand-controller.txt +++ /dev/null @@ -1,53 +0,0 @@ -* Cadence NAND controller - -Required properties: - - compatible : "cdns,hp-nfc" - - reg : Contains two entries, each of which is a tuple consisting of a - physical address and length.
