Subject[PATCH v5 11/23] drm/tegra: Probe dpaux devices on demand
Date
When looking up a dpaux device through its OF node, probe it if it
hasn't already.

The goal is to reduce deferred probes to a minimum, as it makes it very
cumbersome to find out why a device failed to probe, and can introduce
very big delays in when a critical device is probed.
