LS1046A: How to use IRQ by low level-sensitive

yoshimorizumi — Thu, 06 Sep 2018 10:00:55 GMT

Hi,

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.

https://lkml.org/lkml/2017/12/4/406

https://lkml.org/lkml/2018/2/23/1257
https://lkml.org/lkml/2018/2/23/1264

If this correction is appropriate, could you apply to next LSDK release?
