[PATCH 0/9] rtc: convert multiple bindings into dtschema

[PATCH 0/9] rtc: convert multiple bindings into dtschema

[Javier Carrasco]

This series converts the following bindings into dtschema, moving them
to trivial-rtc whenever possible:

- orion-rtc: trival-rtc, referenced in arm arch.
- google,goldfish-rtc: trivial-rtc, referenced in mips arch.
- lpc32xx-rtc: trival-rtc, referenced in arm arch.
- maxim,ds1742: trivial-rtc, not referenced in arch, cheap conversion.
- rtc-aspeed: 3 devices to trivial-rtc, all referenced in arm arch.
- pxa-rtc: add missing properties and convert. Referenced in arm arch.
- st,spear600-rtc: trivial-rtc, referenced in arm arch.
- stmp3xxx-rtc: convert, referenced in arm arch.
- via,vt8500-rtc: trivial-rtc, referenced in arm arch.

[PATCH 1/9] dt-bindings: rtc: orion-rtc: move to trivial-rtc

[Javier Carrasco]

This RTC requires a compatible, a reg and a single interrupt,
which makes it suitable for a direct conversion into trivial-rtc.

This one no... and if you tested DTS you would see errors, although you
need to test specific lpc config, not multi_v7.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

Anyway, you *must* check all DTS before moving anything to trivial.

Does it mean all other bindings were not checked against DTS at all?

Best regards,
Krzysztof

Hi,

I did check the conversion against nxp/lpc/lpc3250-phy3250.dts, which
throws a message about the 'clocks' property.

That property is not documented in the original binding, and even though
it could be missing, I could not find any function to get a clock (i.e.
any form of clk_get()) in rtc-lpc32xx.c, which is the only file where
the compatible can be found.

Is therefore the property not useless in the dts? My apologies if I am
missing something here.

Thanks and best regards,
Javier Carrasco

Old bindings are not really accurate.

Useless for whom? For Linux yes. For U-Boot or out-of-tree users of DTS,
I don't know. Anyway the true question is if there is a clock or there
is no. If there is a clock, then it should be in the binding even if
Linux driver does not use it.

I propose to add it and be done with it.




Best regards,
Krzysztof

The bindings doesn't document the driver but the hardware. In this case,
the only input clock seems to be a 32kHz crystal.

[Javier Carrasco]

This RTC only requires the compatible a reg and properties,
which makes it suitable for a direct conversion into trivial-rtc.

[Javier Carrasco]

Convert existing binding to dtschema to support validation.

The missing 'reg' and 'interrupts' properties have been added, taking
the 2 supported interrupts into account to fix the example.

[PATCH 8/9] dt-bindings: rtc: stmp3xxx-rtc: convert to dtschema

[Javier Carrasco]

Convert existing binding to dtschema to support validation.

The 'fsl,imx28-rtc' compatible is currently not supported, and it is
only referenced in this binding and in nxp/mxs/imx28.dtsi. Therefore,
that compatible has been dropped, which triggers a warning when testing
the DT against the new binding.

There is another reference to fsl,stmp3xxx-rtc in nxp/mxs/imx23.dtsi,
where another unsupported compatible 'fsl,imx23-rtc' is used, and the
same problem would arise when testing the file against the new binding.

There is no driver that will match 'fsl,imx28-rtc', only
'fsl,stmp3xxx-rtc', so I am not sure how to document the missing
compatible in a sensible way. My first suggestion to account for
undocumented strings would be:

  compatible:
    oneOf:
      - items:
          - enum:
              - fsl,imx23-rtc
              - fsl,imx28-rtc
          - const: fsl,stmp3xxx-rtc
      - const: fsl,stmp3xxx-rtc

Any suggestions or improvements?

The difference is that 'fsl,imx23-rtc' was not even mentioned in any
binding, and it can only be found in imx23.dtsi. 'fsl,imx28-rtc' was
indeed mentioned in the txt binding.

My understanding after your comment is that we should gather
undocumented compatibles and add them to the bindings they would belong
to,no matter if they are used anywhere or not. I added this one to the
suggestion above as well.

I don't understand what driver matching to it has anything to do with
the problem discussed here.

You have DTS, so you can see how it should be written.

Bindings are not correct. Many times.

What do you mean "unused"? If these you call unused, then shall we
remove 90% of such "unused" compatibles from the binding? No. See
writing bindings or hundreds of other bindings as examples. You need
specific part.

[PATCH 9/9] dt-bindings: rtc: via,vt8500-rtc: move to trivial-rtc

[Javier Carrasco]

The RTC documented in this binding requires a compatible, a reg
and a single interrupt, which makes it suitable for a direct
conversion into trivial-rtc.

Probably all the moves to trivial-rtc can be squashed.
