I'm using linux-4.9.35 which is based on LSDK-1709, on the LS1046ARDB.
I set the following entry to DTS file, because I wanted to use IRQ1 by "low level-sensitive".
interrupts = <GIC_SPI 132 IRQ_TYPE_LEVEL_LOW>;
However, request_irq() returns the error (EINVAL) by driver's initialization routine.
At that time, the following messages were output.
genirq: Setting trigger mode 8 for irq 27 failed (gic_set_type+0x0/0x60)
I applied to the correction shown by the following threads, when the problem was solved.
If this correction is appropriate, could you apply to next LSDK release?
