Subject: [PATCH v2 0/12] Discover and probe dependencies
Date: Wed, 1 Jul 2015 11:40:55 +0200 [thread overview]
Message-ID: <1435743667-11987-1-git-send-email-tomeu.vizoso@collabora.com> (raw)
Hi,
this is version 2 of a series that probes devices in dependency order so
as to avoid deferred probes. While deferred probing is a powerful
solution that makes sure that you eventually get a working system at the
end of the boot, can make it very time consuming to find out why a
device didn't probe and can also introduce big delays in when a device
actually probes by sending it to the end of the deferred queue.
So far I have only tested on a Tegra124 Chromebook.
Thanks,
Tomeu
Changes in v2:
- Instead of delaying all probes until late_initcall, only delay matches
of platform devices that have a firmware node attached.
- Allow bindings implementations register a function instead of using
class callbacks, as not only subsystems implement firmware bindings.
- Move strends to string.h
- Document that consumers of backlight devices can use the 'backlight'
property to hold a phandle to the backlight device.
- Allocate the list of dependencies and pass it to the function that
fills it.
