-Meson SoCs contains an interrupt controller which is able to watch the SoC
-pads and generate an interrupt on edge or level. The controller is essentially
-a 256 pads to 8 GIC interrupt multiplexer, with a filter block to select edge
-or level and polarity. It does not expose all 256 mux inputs because the

-Required properties:
-
-- compatible : must have "amlogic,meson8-gpio-intc" and either
- "amlogic,meson8-gpio-intc" for meson8 SoCs (S802) or
- "amlogic,meson8b-gpio-intc" for meson8b SoCs (S805) or
- "amlogic,meson-gxbb-gpio-intc" for GXBB SoCs (S905) or
- "amlogic,meson-gxl-gpio-intc" for GXL SoCs (S905X, S912)
- "amlogic,meson-axg-gpio-intc" for AXG SoCs (A113D, A113X)
- "amlogic,meson-g12a-gpio-intc" for G12A SoCs (S905D2, S905X2, S905Y2)
- "amlogic,meson-sm1-gpio-intc" for SM1 SoCs (S905D3, S905X3, S905Y3)

- "amlogic,meson-s4-gpio-intc" for S4 SoCs (S802X2, S905Y4, S805X2G, S905W2)
-- reg : Specifies base physical address and size of the registers.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value must be 2.
-- meson,channel-interrupts: Array with the 8 upstream hwirq numbers. These

Maybe just take it through your Amlogic SoC tree in such case? It's less
preferred than subsystem, but still what matters is to get this merged.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.5/drivers)
[1/1] dt-bindings: interrupt-controller: Convert Amlogic Meson GPIO interrupt controller binding
https://git.kernel.org/amlogic/c/6b0139b372d40bd5dafc140b6618b57d13211168
These changes has been applied on the intermediate git tree [1].
The v6.5/drivers branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.
In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].
The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.
If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.

At first adjust some existing dtbs's so that they pass dtbs_check
after switching bindings to yaml.
Then switch further Amlogic Meson bindings to yaml.
Tested with make targets dt_binding_check and dtbs_check.

+
+description: |
+ Meson SoCs contains an interrupt controller which is able to watch the SoC
+ pads and generate an interrupt on edge or level. The controller is essentially
+ a 256 pads to 8 GIC interrupt multiplexer, with a filter block to select edge
+ or level and polarity. It does not expose all 256 mux inputs because the
+ documentation shows that the upper part is not mapped to any pad. The actual
+ number of interrupt exposed depends on the SoC.
