From: Niravkumar L Rabara <niravkumar.l.rabara@intel.com>

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 <niravkumar.l.rabara@intel.com>
---

Changes in v4:
- Fixed the identation for examples as per review comment in v3.

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>;

-	  interrupts = <2 0>;

Looks good to me, but I'll wait for binding maintainers ack ofc.

Thanks,

There was one, but author ignored it.

My apologies, I forgot to include the 'Reviewed-by: Conor Dooley conor.dooley@microchip.com' tag that I received in the v3 patch. I will ensure this does not happen again.

Thanks,

Please re-send with the missing tag(s), otherwise they will not be
picked-up (automatically).

This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation: Please add
Acked-by/Reviewed-by/Tested-by tags when posting new versions, under
or above your Signed-off-by tag. Tag is "received", when provided
in a message replied to you on the mailing list. Tools like b4 can help
here. However, there's no need to repost patches *only* to add the tags.
The upstream maintainer will do that for tags received on the version
they apply.

https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed.
</form letter>

Best regards,
Krzysztof
