ARM: dts: armada-38x: Fix irq type for pca955
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: 928413bd859c ("ARM: mvebu: Add Armada 388 General Purpose Development Board support") Cc: stable@vger.kernel.org Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
