I was hoping to represent this as a different compatible value, in the
same way as one of Tegra's I2C controllers is, eg. nvidia,tegra20-ehci
and nvidia,tegra20-ehci-legacy.
However, I suppose representing this using a property is OK too.
Either way, can you please also push this patch to the Linux kernel (and
the associated changes to tegra*.dtsi) in order to run it past the other
Tegra maintainers before committing to it within U-Boot.
Thanks.
