Subject: [PATCH v1] riscv: dts: starfive: Remove PMIC interrupt info for Visionfive 2 board

Since commit b2cb2ae22278f1918f7526b89760ee00b4a81393 ("mfd: axp20x:
Generalise handling without interrupt"), interrupt info part for the
AXP15060 PMIC is not needed anymore for Statfive Visionfive 2 board.
And this would cause kernel to try to enable interrupt line 0, which is
not expected. So delete this part from device tree.

interrupt-controller/#interrupt-cells are required properties, you can't
delete them. If you ran dtbs_check you'd see that it complains about
this patch.

If you just remove the interrupts property, what happens?

This Fixes tag cannot be right, a dts patch cannot fix a driver. The dts
patch that incorrectly said this used interrupt 0 is what should be in the
Fixes tag.

Thanks,
Conor.

Hi Conor,

Thanks for reply. I’m sorry for this, but my distro’s dt-schema
is too old to run dtbs-check. Will fix in next version.

Best regards
