[PATCH v6 2/4] dt-bindings: eeprom: at25: Add Anvo ANV32E61W

[Krzysztof Kozlowski]

Document the compatible for ANV32E61W 64kb Serial SPI non-volatile SRAM.
Although it is a SRAM device, it can be accessed through EEPROM
interface. At least until there is no proper SRAM driver support for
it.

[PATCH v6 4/4] ARM: dts: imx6ul-kontron-n6310: Add Kontron i.MX6UL N6310 SoM and boards

[Krzysztof Kozlowski]

Add support for i.MX6UL modules from Kontron Electronics GmbH (before
acquisition: Exceet Electronics) and evalkit boards based on it:

1. N6310 SOM: i.MX6 UL System-on-Module, a 25x25 mm solderable module
   (LGA pads and pin castellations) with 256 MB RAM, 1 MB NOR-Flash,
   256 MB NAND and other interfaces,
2. N6310 S: evalkit, w/wo eMMC, without display,
3. N6310 S 43: evalkit with 4.3" display,

The work is based on Exceet/Kontron source code (GPLv2) with numerous
changes:
1. Reorganize files,
2. Rename Exceet -> Kontron,
3. Rename models/compatibles to match newest Kontron product naming,
4. Fix coding style errors and adjust to device tree coding guidelines,
5. Fix DTC warnings,
6. Extend compatibles so eval boards inherit the SoM compatible,
7. Use defines instead of GPIO and interrupt flag values,
8. Use proper vendor compatible for Macronix SPI NOR,
9. Replace deprecated bindings with proper ones,
10. Sort nodes alphabetically,
11. Remove Admatec display nodes (not yet supported).

Changes since v5:
1. Split Documentation/devicetree/bindings/arm/fsl.yaml update to
   separate patch.

Changes since v4:
1. Split Documentation/devicetree/bindings/eeprom/at25.txt update to
   separate patch.

Changes since v3, after Shawn's review:
1. Split bindings update to patch 2/3,
2. Remove unsupported displays from (Admatec),
3. Remove N6310 S 50 board (same as N6310 S 43 since there is no Admatec
   display),
4. Order iomux nodes by name, minor cleanup,
5. Use wakeup-source instead of enable-sdio-wakeup,
6. Add review tags.

Changes since v2, after Fabio's review:
1. Add "imx6ul" compatible to board name (that's what I understood from
   review),
2. Add vendor/device prefix to eeprom and document the compatible,
3. Use "admatecde" as vendor compatible to avoid confusion with Admatec
   AG in Switzerland (also making LCD panels),
4. Use generic names for nodes,
5. Use IRQ_TYPE_LEVEL_LOW,
6. Move iomux to the end of files,
7. Remove regulators node (include regulators in top level),
8. Remove cpu clock-frequency,
9. Other minor fixes pointed by Fabio.

Changes since v1, after Frieder's review:
1. Remove unneeded license notes,
2. Add Kontron copyright (2018),
3. Rename the files/models/compatibles to new naming - N6310,
4. Remove unneeded CPU operating points override,
5. Switch regulator nodes into simple children nodes without addresses
   (so not simple bus),
6. Use proper vendor compatible for Macronix SPI NOR.

This doesn't match what is in your dts files. Run 'make dtbs_check' and see.

You mean the name does not match? I thought that '#' is a comment in YAML...

The dtbs_check fail on missing dt-mk-schema. Any reason why it is not
in the scripts?

No, the number of compatible strings is the problem.

Because it is not just that script, but the whole project of scripts,
schemas and meta-schemas. Read the instructions in
Documentation/devicetree/writing-schema.md(.rst in next).

I see. If I understand the schema correctly, this should look like:

It passes the dtbs_check. Is it correct?

Looks correct, but a couple of comments.

Is the SOM ever used alone? If not, then no point in listing this here.

This could be a 'const' instead. It depends if you think there will
ever be more than one entry.

SoM alone: no, because it requires some type of base board. However it
will be used by some customer designs with some amount of
changes/addons.

Looking at other aproaches, usually SoMs have their own compatible.  In
such case - I should document it somewhere.

Indeed, I'll make this and entry below for S 43 board const.

I wasn't suggesting not having the compatible for it, but you don't
need it in this list because that is not valid. You have to list it
with the base board compatibles.

The diff against v7 would be like this then:
---
diff --git a/Documentation/devicetree/bindings/arm/fsl.yaml
b/Documentation/devicetree/bindings/arm/fsl.yaml
index 1f440817fc03..7219c15f6185 100644
--- a/Documentation/devicetree/bindings/arm/fsl.yaml
+++ b/Documentation/devicetree/bindings/arm/fsl.yaml
@@ -161,7 +161,6 @@ properties:
         items:
           - enum:

This passes the dtbs_check.

I'll send v8
