Hi Alexandre Belloni, Is it ok, if I send isl1208 driver enhancement patches patch#5 to patch#10, as it has no dependencies? Patch#11 will send later based on the discussion [1] [1] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20230602142426.438375-2-biju.das.jz@bp.renesas.com/ Cheers, Biju > -----Original Message----- > From: Biju Das <biju.das.jz@bp.renesas.com> > Sent: Friday, June 2, 2023 3:24 PM > To: Alessandro Zummo <a.zummo@towertech.it>; Alexandre Belloni > <alexandre.belloni@bootlin.com>; Rob Herring <robh+dt@kernel.org>; > Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org>; Conor Dooley > <conor+dt@kernel.org> > Cc: Biju Das <biju.das.jz@bp.renesas.com>; Trent Piepho > <tpiepho@gmail.com>; linux-rtc@vger.kernel.org; > devicetree@vger.kernel.org; Geert Uytterhoeven <geert+renesas@glider.be>; > Fabrizio Castro <fabrizio.castro.jz@renesas.com>; linux-renesas- > soc@vger.kernel.org; Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> > Subject: [PATCH v6 05/11] dt-bindings: rtc: isl1208: Convert to json- > schema > > Convert the isl1208 RTC device tree binding documentation to json-schema. > > Update the example to match reality. > > Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> > Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> > --- > v5->v6: > * No change > v4_new->v5: > * No change. > v4->v4_new: > * Moved this patch to PMIC series > * Added minItems to interrupt-names. > * Added interrupt-names in conditional schema check. > v3->v4: > * Added Rb tag from Krzysztof Kozlowski. > * Dropped | from description > * Replaced the pin name #EVDET->EVDET in description. > * Dropped oneOf from compatible. > v2->v3: > * Updated interrupt-names property by keeping the list of names. > * Removed Interrupts from required property as it may not be wired. > * Removed isil,ev-evienb from required property. > RFC->v2: > * Updated maintainers list > * Updated description from original bindings > * removed default from isil,ev-evienb properties to match with the > original > bindings. > * Added conditional check for interrupts. > --- > .../devicetree/bindings/rtc/isil,isl1208.txt | 38 -------- > .../devicetree/bindings/rtc/isil,isl1208.yaml | 89 +++++++++++++++++++ > 2 files changed, 89 insertions(+), 38 deletions(-) delete mode 100644 > Documentation/devicetree/bindings/rtc/isil,isl1208.txt > create mode 100644 > Documentation/devicetree/bindings/rtc/isil,isl1208.yaml > > diff --git a/Documentation/devicetree/bindings/rtc/isil,isl1208.txt > b/Documentation/devicetree/bindings/rtc/isil,isl1208.txt > deleted file mode 100644 > index 51f003006f04..000000000000 > --- a/Documentation/devicetree/bindings/rtc/isil,isl1208.txt > +++ /dev/null > @@ -1,38 +0,0 @@ > -Intersil ISL1209/19 I2C RTC/Alarm chip with event in > - > -ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while > the > -ISL1208 and ISL1218 do not.

I still don't know why you say this and changed the example to be as simple as possible. Did you test it and does it not work with the actual driver? I looked at the code for parsing OF interrupts and it does not look like anything has changed to make it not work. Nor do I see anything incorrect in the original example.

Can you explain what you think is wrong with the > original example? There is nothing wrong with example. The only reason is there is no dts in mainline matching with example. If I am correct, example should match with reality. If it is not the case, I am happy to update the example. I have seen people(including me) sending patches to update example with reality. Note: Can you please confirm rtctest[1] is passing with interrupts in your environment? In my board interrupt is not populated. So it is good to know RTC test which involves IRQ is passing in your environment.

It should have one, no? Although I am new as of -rc1 and the information is unlikely to have propagated far maintainers wise. https://www.kernel.org/doc/html/latest/process/maintainers.html#open-firmware-and-flattened-device-tree-bindings Cheers, Conor.
