Add YAML scheme for the Marvell's NAND controller
to validate it's DT bindings. Old txt file is deleted,
not included the compatibles and properties which were marked as
deprecated.
Also fix node name in cp11x DTSI acording to nand-controller.yaml
I've picked up this series to hopefully get it over the line. I think I've
addressed all the feedback from the last round of review.

Notes:
Changes in v6:
- remove properties covered by nand-controller.yaml
- add example using armada-8k compatible
earlier changes:
v5:
1) Get back "label" and "partitions" properties but without
ref to the "partition.yaml" which was wrongly used.
2) Add "additionalProperties: false" for nand@ because all possible
properties are described.
v4:
1) Remove "label" and "partitions" properties
2) Use 2 clocks for A7K/8K platform which is a requirement
v3:
1) Remove txt version from the MAINTAINERS list
2) Use enum for some of compatible strings
3) Drop:
#address-cells
#size-cells:
as they are inherited from the nand-controller.yaml
4) Add restriction to use 2 clocks for A8K SoC
5) Dropped description for clock-names and extend it with
minItems: 1
6) Drop description for "dmas"
7) Use "unevalautedProperties: false"
8) Drop quites from yaml refs.
9) Use 4-space indentation for the example section
v2:
1) Fixed warning by yamllint with incorrect indentation for compatible list

-Marvell NAND Flash Controller (NFC)
-
-Required properties:
-- compatible: can be one of the following:
- * "marvell,armada-8k-nand-controller"
- * "marvell,armada370-nand-controller"
- * "marvell,pxa3xx-nand-controller"
- * "marvell,armada-8k-nand" (deprecated)
- * "marvell,armada370-nand" (deprecated)
- * "marvell,pxa3xx-nand" (deprecated)
- Compatibles marked deprecated support only the old bindings described
- at the bottom.
-- reg: NAND flash controller memory area.
-- #address-cells: shall be set to 1. Encode the NAND CS.
-- #size-cells: shall be set to 0.
-- interrupts: shall define the NAND controller interrupt.
-- clocks: shall reference the NAND controller clocks, the second one is
- is only needed for the Armada 7K/8K SoCs
-- clock-names: mandatory if there is a second clock, in this case there
- should be one clock named "core" and another one named "reg"
-- marvell,system-controller: Set to retrieve the syscon node that handles
- NAND controller related registers (only required with the
- "marvell,armada-8k-nand[-controller]" compatibles).
-
-Optional properties:
-- label: see partition.txt. New platforms shall omit this property.
-- dmas: shall reference DMA channel associated to the NAND controller.
- This property is only used with "marvell,pxa3xx-nand[-controller]"
- compatible strings.
-- dma-names: shall be "rxtx".
- This property is only used with "marvell,pxa3xx-nand[-controller]"
- compatible strings.
-
-Optional children nodes:
-Children nodes represent the available NAND chips.
-
-Required properties:
-- reg: shall contain the native Chip Select ids (0-3).
-- nand-rb: see nand-controller.yaml (0-1).
-
-Optional properties:
-- marvell,nand-keep-config: orders the driver not to take the timings
- from the core and leaving them completely untouched. Bootloader
- timings will then be used.
-- label: MTD name.
-- nand-on-flash-bbt: see nand-controller.yaml.
-- nand-ecc-mode: see nand-controller.yaml. Will use hardware ECC if not specified.
-- nand-ecc-algo: see nand-controller.yaml. This property is essentially useful when
- not using hardware ECC. Howerver, it may be added when using hardware
- ECC for clarification but will be ignored by the driver because ECC
- mode is chosen depending on the page size and the strength required by
- the NAND chip. This value may be overwritten with nand-ecc-strength
- property.
-- nand-ecc-strength: see nand-controller.yaml.
-- nand-ecc-step-size: see nand-controller.yaml. Marvell's NAND flash controller does
- use fixed strength (1-bit for Hamming, 16-bit for BCH), so the actual
- step size will shrink or grow in order to fit the required strength.
- Step sizes are not completely random for all and follow certain
- patterns described in AN-379, "Marvell SoC NFC ECC".
-
-See Documentation/devicetree/bindings/mtd/nand-controller.yaml for more details on
-generic bindings.
-
-
-Example:
-nand_controller: nand-controller@d0000 {
- compatible = "marvell,armada370-nand-controller";
- reg = <0xd0000 0x54>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&coredivclk 0>;
-
- nand@0 {
- reg = <0>;
- label = "main-storage";
- nand-rb = <0>;
- nand-ecc-mode = "hw";
- marvell,nand-keep-config;
- nand-on-flash-bbt;
- nand-ecc-strength = <4>;
- nand-ecc-step-size = <512>;
-
- partitions {
- compatible = "fixed-partitions";
- #address-cells = <1>;
- #size-cells = <1>;
-
- partition@0 {
- label = "Rootfs";
- reg = <0x00000000 0x40000000>;
- };
- };
- };
-};
-
-
-Note on legacy bindings: One can find, in not-updated device trees,
-bindings slightly different than described above with other properties
-described below as well as the partitions node at the root of a so
-called "nand" node (without clear controller/chip separation).
-
-Legacy properties:
-- marvell,nand-enable-arbiter: To enable the arbiter, all boards blindly
- used it, this bit was set by the bootloader for many boards and even if
- it is marked reserved in several datasheets, it might be needed to set
- it (otherwise it is harmless) so whether or not this property is set,
- the bit is selected by the driver.
-- num-cs: Number of chip-select lines to use, all boards blindly set 1
- to this and for a reason, other values would have failed. The value of
- this property is ignored.
-
-Example:
-
- nand0: nand@43100000 {
- compatible = "marvell,pxa3xx-nand";
- reg = <0x43100000 90>;
- interrupts = <45>;
- dmas = <&pdma 97 0>;
- dma-names = "rxtx";
- #address-cells = <1>;
- marvell,nand-keep-config;
- marvell,nand-enable-arbiter;
- num-cs = <1>;
- /* Partitions (optional) */
- };

Notes:
Changes in v6:
- remove properties covered by nand-controller.yaml
- add example using armada-8k compatible
earlier changes:
v5:
1) Get back "label" and "partitions" properties but without
ref to the "partition.yaml" which was wrongly used.
2) Add "additionalProperties: false" for nand@ because all possible
properties are described.
v4:
1) Remove "label" and "partitions" properties
2) Use 2 clocks for A7K/8K platform which is a requirement
v3:
1) Remove txt version from the MAINTAINERS list
2) Use enum for some of compatible strings
3) Drop:
#address-cells
#size-cells:
as they are inherited from the nand-controller.yaml
4) Add restriction to use 2 clocks for A8K SoC
5) Dropped description for clock-names and extend it with
minItems: 1
6) Drop description for "dmas"
7) Use "unevalautedProperties: false"
8) Drop quites from yaml refs.
9) Use 4-space indentation for the example section
v2:
1) Fixed warning by yamllint with incorrect indentation for compatible list

You miss here deprecated compatibles, which are BTW still used. Don't

It's an array, so this does not sound right. You might want to put it
under items:. Then you also miss min/maxItems.

Running 'make dtbs_check' with the schema in this patch gives the

incorrect. These may not be new warnings.
Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

label and partitions are defined in partitions/partition.yaml,
referenced by partitions.yaml, referenced by mtd.yaml, referenced by
nand-chip.yaml, referenced by nand-controller.yaml, itself referenced
in this file :-)
So I believe there is nothing else to add in the controller's binding
for these two properties? They are very generic, it would not be
optimal if we had to take care about them.

I did not bother converting this file yet but I actually rewrote the
corresponding Linux driver (5 years ago) entirely so I don't mind.

That's true, you can have either one or two members with the value
[0-1], so you need both.

The controller (and the driver) actually supports 1, 4, 8, 12, 16.

That's true, you can have either one or two members with the value
[0-1], so you need both.

This is resolved in patch 2/2. I can swap the order in the series if it
helps.

This is resolved in patch 2/2. I can swap the order in the series if it
helps.

I've been running `make ARCH=arm64 dtbs_check
DT_SCHEMA_FILES=marvell,nand-controller.yaml` (and similar for arm) but
didn't see these am I doing something wrong or did I just fail to look
properly.

Hmm it doesn't appear t be picking them up. I was only getting away with

Hmm it doesn't appear t be picking them up. I was only getting away with

Is there any way to indicate that a compatible value is deprecated? I
know how to mark a property as deprecated but how do I indicate this for
specific compatible values?

The same way. git grep -C 5 compatible. First result in the DT bindings...
