Subject: [PATCH v3] dt-bindings: mtd: cadence: convert cadence-nand-controller.txt to yaml

From: Niravkumar L Rabara <[email protected]>

Convert cadence-nand-controller.txt to yaml format.
Update cadence-nand-controller.txt to cdns,hp-nfc.yaml in MAINTAINER file.

Signed-off-by: Niravkumar L Rabara <[email protected]>
---

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.

-* 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. The first entry is the address and
- length of the controller register set. The second entry is the
- address and length of the Slave DMA data port.
- - reg-names: should contain "reg" and "sdma"
- - #address-cells: should be 1. The cell encodes the chip select connection.
- - #size-cells : should be 0.
- - interrupts : The interrupt number.
- - clocks: phandle of the controller core clock (nf_clk).
-
-Optional properties:
- - dmas: shall reference DMA channel associated to the NAND controller
- - cdns,board-delay-ps : Estimated Board delay. The value includes the total
- round trip delay for the signals and is used for deciding on values
- associated with data read capture. The example formula for SDR mode is
- the following:
- board delay = RE#PAD delay + PCB trace to device + PCB trace from device
- + DQ PAD delay
-
-Child nodes represent the available NAND chips.
-
-Required properties of NAND chips:
- - reg: shall contain the native Chip Select ids from 0 to max supported by
- the cadence nand flash controller
-
-See Documentation/devicetree/bindings/mtd/nand-controller.yaml for more details on
-generic bindings.
-
-Example:
-
-nand_controller: nand-controller@60000000 {
- compatible = "cdns,hp-nfc";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x60000000 0x10000>, <0x80000000 0x10000>;

You still have wrong indentation here.
