[PATCH v2 12/22] drm/tegra: Probe dpaux devices on demand

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When looking up a dpaux device through its firmware 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.
