SubjectRe: [linux-sunxi] [PATCH 11/14] ARM: sunxi: dts: s3/s3l/v3: add DTSI files for S3/S3L/V3 SoCs
From
Date
Hi,

Le mardi 12 mars 2019 à 23:22 +0800, Icenowy Zheng a écrit :

Note that the V3 has a NMI controller at 1c000d0, that is required for
handling the AXP209 interrupts IIRQ. I have no idea whether it's also
the case on the V3s/S3/S3L though but it would be good to know.

Note that I can totally add support for it when adding support for my
V3 device that uses the AXP209 this way.

Also, could we get proper compatibles and config options for these new
SoCs, since they are distinct from the V3S?

Cheers,

Paul
