* ARM: ux500: move top level platform devices in sysfs to /sys/devices/socXLee Jones2012-02-131-1/+7
| | | | | | | | | | | | | 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.

* ARM: ux500: export System-on-Chip information ux500 via sysfsLee Jones2012-02-131-6/+27
| | | | | | | | | | | | | | | | 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.

* ARM: ux500: pass parent pointer to each platform deviceLee Jones2012-02-131-7/+8
| | | | | | | | | | | | | 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>

| * ARM: ux500: remove support for early silicon revisionsLinus Walleij2011-12-191-28/+2
| | | | | | | | | | | | | | | | | | | | | | The DB8500 ED (Early Drop) and V1 are only available inside of ST-Ericsson or partners, we have actively replaced and scrapped these prototypes. All Nova products on the open market (such as the Snowball board) are based on V2 and later ASIC variants. So let us focus on supporting the silicon that will be used and delete this to get a clear overview. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

|/ | | | | | | | | | | | | The overlapping iotable mapping entries for the ux500 Cortex A9 SCU, CPU control and TWD are no longer accepted by the kernel. Remove the overlaps so the machine boots again.

* mfd: update DB8500 PRCMU driverMattias Nilsson2011-05-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | This updates the DB8500 PRCMU driver to the latest version available internally. Nominally we would update the dependent CPUfreq driver at the same time but since that is being moved around in this patch set we postpone that by simply deactivating it for the time being. This is a snapshot of the current PRCMU firmware API as it looks right now. The PRCMU firmware is still subject to change. This also updates the CPUfreq driver to a newer version that will utilize the new API.
