But after reading Angelo's comment, we thought it is necessary to create a new compatible to avoid confusion for users. https://lore.kernel.org/lkml/bf8394c6-5460-8696-f46b-0c39927aaf84@collabora.com/ Although they are fully compatible, developers cannot arbitrarily replace the chip on the board with another one. So separated bindings might be better. > Best regards, > Krzysztof Thanks Macpaul Lin

However we did not ask to remove a compatible of compatible devices. You also need it. Otherwise how your compatibility is going to work? Best regards, Krzysztof

This keeps a format with -regulator is because I've found some other use cases. It seems "-regulator" or "regulator-" could be arbitrary. I'm not sure if it is a new guideline for regulator's node. If there is in the devicetree document, maybe I just missed it? However if this is for the purpose of keeping the DTS format tidy, I will update it in the next version, also fix another "usb-otg-vbus-regulator" node. arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts a1d3281450ab2 (Christopher Obbard 2023-01-09 16:58:01 +0100 46) vcc5v0_sys: vcc5v0-sys-regulator { arch/arm64/boot/dts/rockchip/rk3566-anbernic-rgxx3.dtsi 523adb553573d (Chris Morgan 2022-09-06 16:03:24 -0500 256) vcc_wifi: regulator-vcc-wifi { > Thank you. > > Best regards, > Krzysztof Thanks.

What is the point to name in the same DTS some of the regulators "regulator-foo" and some "foo-regulator"? Best regards, Krzysztof

So separated bindings might be better. Sorry you've misunderstood; I was trying to explain to Krzysztof that the two SoCs are fully compatible... my suggestion was in like with what you're trying to do as in I am agreeing with your first version, Macpaul, to inherit MT8195.

Can you please only target Reviewers/Maintainers and mailinglists reported by get_maintainers script? I have only sent patches for mediatek and did some tests. So i'm not interested in patches for hardware i do not have here :). I guess i'm not alone... regards Frank

1. Add compatible for MT8395. 2. Add bindings for the MediaTek mt8395-evk board, also known as the "Genio 1200-EVK". The MT8195 and MT8395 belong to the same SoC family, with only minor differences in their physical characteristics. They utilize unique efuse values for differentiation.
