I only checked berlin2.dtsi:
The top most line with <GIC_SPI 15 ...> belongs to a sub-node of
apb@fc0000 - which means that the pwm node isn't sorted in by
address. Please sort the nodes by address in all three DT patches.

BTW, is there any IRQ from the PWM IP routed to any intc upstream?
A quick look into some BSP code does not reveal any hints maybe
one of the Marvell guys can comment on it.
