Add YAML scheme for the Marvell's NAND controller
to validate it's DT bindings. Old txt file is deleted.
Also fix node name in cp11x DTSI according 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 earlier rounds of review.
As of v7 I've re-ordered the patches so the fixups for the device trees come
before the schema so if the series is applied in order the various checkers
should pass cleanly. This is reliant on a series from Miquel tightening up some
of the requirements on mtd/nand chips so the checkers may complain unless those
changes are picked up too.
For v10 the dts patches have been picked up by the ARM maintainers so I've not
included them in this round.

2.40.1
From: Vadym Kochan <[email protected]>
Switch the DT binding to a YAML schema to enable the DT validation.
There was also an incorrect reference to dma-names being "rxtx" where
the driver and existing device trees actually use dma-names = "data" so
this is corrected in the conversion.

Notes:
Changes in v10:
- Formatting for description
- Restrict clocks to 1 item for non-8K devices
- Don't allow "marvell,armada-8k-nand-controller" without
"marvell,armada370-nand-controller" (undoes a change from v8)
Changes in v9:
- depend on series from Miquel
https://lore.kernel.org/linux-mtd/[email protected]/
- enforce minimum/maximum for nand-rb
- move required: block for controller
- move unevaluatedProperties: for nand chip
- remove label, partitions and nand-on-flash-bbt which are covered by
generic schema
Changes in v8:
- Mark deprecated compatible values as such
- Allow "marvell,armada-8k-nand-controller" without
"marvell,armada370-nand-controller"
- Make dma-names usage reflect reality
- Update commit message
Changes in v7:
- Restore "label" and "partitions" properties (should be picked up via
nand-controller.yaml but aren't)
- Add/restore nand-on-flash-bbt and nand-ecc-mode which aren't covered
by nand-controller.yaml.
- Use "unevalautedProperties: false"
- Corrections for clock-names, dma-names, nand-rb and nand-ecc-strength
- Add pxa3xx-nand-controller example
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) */
- };

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
