This chip uses the same GICv3 as RK356X but has fixed the previous limitation of GIC only supporting 32-bit addresses. We sent this RFC a few weeks back: https://lore.kernel.org/all/CAMdYzYrmq1ftBaBj1XHVWWXUQ4Prr1VpTpunyNOQ2ha-DkXMjQ@mail.gmail.com/ The big change from that RFC to this patch series is the change from ITS quirks to a DMA Non-Coherent flag, as sugested by Robin Murphy. This is work based on prior work from XiaoDong Huang and Peter Geis fixing this issue specifically for Rockchip 356x. Plus comments of Robin Murphy about Non-Coherent properties.
