Hence this patch series drop all such masks where they are still present. This has been compile-tested only. But note that all such masks were removed before from Renesas SoCs in commit 8b6a006c914aac17 ("arm64: dts: renesas: Drop specifying the GIC_CPU_MASK_SIMPLE() for GICv3 systems")). A related question: The GICv3 DT bindings also support only edge-triggered and level-triggered PPI interrupts, without specifying polarity. Apparently, even the common gic_configure_irq() just ignores the polarity, also on pre-GICv3, so specifying IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_LEVEL_HIGH doesn't matter at all? Actual SoC hardware docs (e.g. R-Car Gen4) does document that some PPI interrupts are active-high, while others are active-low. Thanks for your comments!
