The Allwinner S3/S3L/V3 SoCs all share the same die with the V3s SoC, but with more GPIO wired out of the package. Add DTSI files for these SoCs. The DTSI file for V3 just replaces the pinctrl compatible string, and the S3/S3L DTSI files just include theV3quoted
DTSI file.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.It's not mentioned on the datasheet. If it's present, please send a patch.
Indeed, it is not documented but the block is definitely there (and it shows up in Allwinner's kernel source too). I'll send a patch once these series is merged then!
BTW all V3 series chip share the same die (sun8iw8).
Right, so I think it's safe to assume that the controller is there on all of them then. Cheers, Paul
Thanksquoted
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, Paulquoted
