From: Shengyu Qu <wiagn233@xxxxxxxxxxx> commit 0f74c64f0a9f6e1e7cf17bea3d4350fa6581e0d7 upstream. Interrupt line number of the AXP15060 PMIC is not a necessary part of its device tree. Originally the binding required one, so the dts patch added an invalid interrupt that the driver ignored (0) as the interrupt line of the PMIC is not actually connected on this platform. This went unnoticed during review as it would have been a valid interrupt for a GPIO controller, but it is not for the PLIC. The PLIC, on this platform at least, silently ignores the enablement of interrupt 0. Bo Gan is running a modified version of OpenSBI that faults if writes are done to reserved fields, so their kernel runs into problems. Delete the invalid interrupt from the device tree.
