[PATCH v2 4/4] arm64: dts: renesas: r9a09g087: add ICU support
Posted by Cosmin Tanislav 2 months, 1 week ago 
The Renesas RZ/N2H (R9A09G087) SoC has an Interrupt Controller (ICU)
block that routes external interrupts to the GIC's SPIs, with the
ability of level-translation, and can also produce software
and aggregate error interrupts.

Add support for it.

"<0 0x812a0000 0 0x10000>", as per Figure 5.1 ("Unified memory map").

The rest is OK, so

i.e. will queue in renesas-devel for v6.20, with the above fixed.

Please do not apply DTS patches to the irqchip tree, as this will cause
conflicts with the renesas-dts tree: subsequent patches referring to
the "icu" label depend on this patch.

Thank you for dropping this commit!
