Subject: [PATCH 4/5] mach-ux500: move top level platform devices in sysfs to /sys/devices/soc/X
Date: Thu, 1 Sep 2011 13:27:22 +0100 [thread overview]
Message-ID: <1314880043-22517-4-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1314880043-22517-1-git-send-email-lee.jones@linaro.org>
At the request of Arnd Bergmann this patch moves all SoC
platform devices found in sysfs from /sys/devices/platform to
/sys/devices/soc/<SoCNum>_<SocMachine>/. It is believed as the
devices are SoC specific and a /sys/devices/soc node has recently
become available, that this would be a more appropriate place to
display the data.
