[PATCH v5 15/23] usb: phy: Probe phy devices on demand

From: Tomeu Vizoso <hidden>
Date: 2015-09-17 13:01:20
Also in: linux-acpi, linux-arm-kernel, lkml
Subsystem: the rest, usb subsystem · Maintainers: Linus Torvalds, Greg Kroah-Hartman

When looking up a phy 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.

Signed-off-by: Tomeu Vizoso <redacted>
