I tested this on LX2160 and get this error when booting into Linux:
Loading Device Tree to 000000009fff6000, end 000000009fffff3e ... OK gic_v3_its_get_gic_lpi_addr: failed to get gic-lpi-base syscon device
Starting kernel ...

I did not look closely yet. Any idea whats going wrong here?
Thanks, Stefan

I added the following patch to use UCLASS_SYSCON to get gic lpi details.
commit id - 2ae7adc659f7fca9ea65df4318e5bca2b8274310
because the above commit is failing, hence we need this patch. When I tested this I didn't face any issue hence didn't push the above change. In my case it was failing only in the lower uboot version without this patch.

What's the "lower uboot version"?
In any case, it's failing now on the lx2160, since no SYSCON device is found:
$ git grep "gic-lpi-base" arch/arm/lib/gic-v3-its.c: { .compatible = "gic-lpi-base" }, arch/arm/lib/gic-v3-its.c: .name = "gic-lpi-base",
So no device is providing this compatible in the dts anywhere. Or am I missing something?
Thanks, Stefan

U-Boot 2020.01 version.

If you apply this patch it will work. Please let me know if anything more is required or if this patch is the not right way to address the issue.
Thank, Rayagonda

This patch is already applied.
Please let me know if anything more is required or if this patch is the not right way to address the issue.
Again, its not working, as no device is providing "gic-lpi-base" AFICT.

Please add dt node which defines "gic-lpi-base" and other details. @Priyanka Jain priyanka.jain@nxp.com - can you please provide dt node added for your platform lx2160a.
For ex -
gic_lpi_base: syscon@0x8ad70000 { compatible = "gic-lpi-base"; reg = <0x0 0x8ad70000 0x0 0x90000>; max-gic-redistributors = <8>; };
scr { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <1>; ranges = <0x0 0x0 0x61000000 0x05000000>;
gic: interrupt-controller@2c00000 { compatible = "arm,gic-v3"; #interrupt-cells = <3>; #address-cells = <1>; #size-cells = <1>; ranges; interrupt-controller; reg = <0x02c00000 0x010000>, /* GICD */ <0x02e00000 0x600000>; /* GICR */ regmap = <&gic_lpi_base>;
