2012-02-13ARM: ux500: move top level platform devices in sysfs to /sys/devices/socXLee Jones
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>/. 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.

2012-02-13ARM: ux500: export System-on-Chip information ux500 via sysfsLee Jones
Here we make use of the new System-On-Chip bus driver to export vital SoC information out to userspace via sysfs. This patch provides a data structure of strings to populate the base nodes found in: /sys/devices/soc[0|1|2|...]/[family|machine|revision|soc_id]. It also adds one more node as requested by ST-Ericsson. 'process' depicts the way in which the silicon was manufactured.

2012-02-13ARM: ux500: pass parent pointer to each platform deviceLee Jones
This patch provides a means for any device within ux500 platform code to allocate its own parent. This is particularly prudent with the introduction of /sys/devices/socX, as a device can now proclaim to be integral part of an SoC, rather than a more generic platform device. Latter patches make good use of this functionality. Signed-off-by: Lee Jones <lee.jones@linaro.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
