[PATCH v2 19/22] phy: core: Probe phy providers on demand

From: Tomeu Vizoso <hidden>
Date: 2015-07-28 13:22:27
Also in: linux-acpi, linux-devicetree, lkml
Subsystem: generic phy framework, the rest · Maintainers: Vinod Koul, Linus Torvalds

When looking up a phy provider 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.

Signed-off-by: Tomeu Vizoso <redacted>
