Subject: [PATCH] leds: convert IDE trigger to common disk trigger
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch converts the IDE specific LED trigger to a generic disk
activity LED trigger. The libata core is now a trigger source just
like before the IDE disk driver. It's merely a replacement of the
string ide by disk.
The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is
widely used by any ibook/powerbook owners with great satisfaction.
Likewise, it is very often used successfully on different ARM platforms.
Unlike the original patch, the existing 'ide-disk' trigger is still
available for backward compatibility. That reduce the amount of patches
in affected device trees out of the mainline kernel. For further
development, the new name 'disk-activity' should be used.
