Subject: [PATCH] ARM: picoxcell: fix missing interrupt-parent properties
Date: Wed, 30 Dec 2020 16:20:05 +0100
Message-ID: <20201230152010.3914962-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

dtc points out that the interrupts for some devices are not parsable:

picoxcell-pc3x2.dtsi:45.19-49.5: Warning (interrupts_property): /paxi/gem@30000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:51.21-55.5: Warning (interrupts_property): /paxi/dmac@40000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:57.21-61.5: Warning (interrupts_property): /paxi/dmac@50000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:233.21-237.5: Warning (interrupts_property): /rwid-axi/axi2pico@c0000000: Missing interrupt-parent

There are two VIC instances, so it's not clear which one needs to be
used. I found the BSP sources that reference VIC0, so use that:
