[Xen-devel] [PATCH WIP v1 04/10] WIP: xen: ns16550: Add nvidia, tegra20-uart to DT compatible list

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

DO NOT APPLY. Doesn't work without sync_console *and* the changes from "HACK:
xen: arm: trying to figure out ns16550 vs. Tegra issue".

I suspect and IRQ or FIFO depth issue. Linux has a separate serial-tegra driver
so perhaps the device is just not as compatible as I think.
