[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 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.

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?

Krzysztof

Instead document missing compatibles and mention this in commit msg.

Please write concise messages... you have to paragraphs about the same?

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.

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

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