    Subject[PATCH AUTOSEL 5.4 28/28] ARM: picoxcell: fix missing interrupt-parent properties
    Date
    From: Arnd Bergmann <arnd@arndb.de>

    [ Upstream commit bac717171971176b78c72d15a8b6961764ab197f ]

    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:
