Add support for atmel legacy nand controllers. These bindings should not be used with the new device trees. Signed-off-by: Balamanikandan Gunasundar <balamanikandan.gunasundar@microchip.com> --- Changes in v2: - Filename matching the compatibles - Remove "bindings" from the subject - Remove "deprecated" as these are the only bindings available for the devices - Add missing constraints. - Add default for nand-ecc-mode - Add 32 in pmecc-cap for sama5d2 - Add default for sector-size, pmecc-lookup-table-offset, nand-bus-width .../devicetree/bindings/mtd/atmel-nand.txt | 116 ------------- .../devicetree/bindings/mtd/atmel-nand.yaml | 163 ++++++++++++++++++ 2 files changed, 163 insertions(+), 116 deletions(-) delete mode 100644 Documentation/devicetree/bindings/mtd/atmel-nand.txt create mode 100644 Documentation/devicetree/bindings/mtd/atmel-nand.yaml
