    ARM: dts: armada-38x: Fix irq type for pca955 · 8d451417
    Gregory CLEMENT 提交于
    As written in the datasheet the PCA955 can only handle low level irq and
    not edge irq.
    
    Without this fix the interrupt is not usable for pca955: the gpio-pca953x
    driver already set the irq type as low level which is incompatible with
    edge type, then the kernel prevents using the interrupt:
    
    "irq: type mismatch, failed to map hwirq-18 for
    /soc/internal-regs/gpio@18100!"
    
    Fixes: 928413bd ("ARM: mvebu: Add Armada 388 General Purpose
    Development Board support")
