[PATCH 0/4] mt8395/mt6359: Fix several dtb-check errors

[Julien Massot]

Hi,
This patch series addresses several dtb-check errors reported for the mt8395-genio-1200-evk.dtb and mt8395-radxa-nio-12l.dtb device trees.

The fixes include:
- Adding the missing #sound-dai-cells property in the mt6397 binding.
- Allowing up to 5 interrupts in the MediaTek IOMMU binding to support MT8395 properly.
- Defining the required compatible property in the regulators node of the mt6359.dtsi.
- Renaming the rtc node to match expected schema naming.

[PATCH 1/4] dt-bindings: mfd: mediatek: mt6397: Add #sound-dai-cells property

[Julien Massot]

The 'mt6359.dtsi' file already uses the '#sound-dai-cells' property.
Add the corresponding property to the binding to fix the following
dtb-check error:

mediatek/mt8395-radxa-nio-12l.dtb: pmic: '#sound-dai-cells', 'mt6359rtc' do not match any of the regexes: 'pinctrl-[0-9]+'

[PATCH 2/4] dt-bindings: iommu: mediatek: mt8195 Accept up to 5 interrupts

[Julien Massot]

Some Mediatek IOMMU can have up to five interrupts so increase
the 'maxItems' to 5.

Fix the following dtb-check error:

Every iommu or just some (as described in commit msg) can have 5

Technically, all of the IOMMUs can have more than one interrupt - but it's not
clear which one and why, as documentation is lacking.

Let's restrict this discussion to MT8195 anyway, as it's the only one declaring
those 5 interrupts...
...all of the IOMMUs declare just one, and mediatek,mt8195-iommu-infra declares 5.

P.S.: Nice catch!

Cheers,
Angelo
