The DB9540 ASIC has bigger PRCMU and PRCMU TCDM memories, so create a separate mapping table for these. Signed-off-by:

This adds support for the U9540 variant of the U8500 series. This is an application processor without internal modem. This is the most basic part with ASIC ID, CPU-related fixes, IRQ list, register ranges, timer, UART, and L2 cache setup. This is based on a patch by Michel Jaouen which was rewritten to fit with the latest 3.3 kernel. ChangeLog v1->v2: deleted the irqs-db9540.h file since we expect to migrate to using Device Tree for getting the IRQs to devices. ChangeLog v2->v3: introduced a fixed virtual offset for the ROM as suggested by Arnd Bergmann. Acked-by:

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. Signed-off-by:

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. Signed-off-by:

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:

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: -

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. Cc: Srinidhi Kasagar <srinidhi.kasagar@stericsson.com> Cc: Rabin Vincent <rabin.vincent@stericsson.com> Reported-by:

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. Acked-by:

This patch adds support for checking if the digital baseband (DB) System-on-Chip (aka "cpu) ASIC hardware version is 1.0, 1.1 or 2.0. We print the result in the bootlog, the functions are then used for runtime decisions based on hardware version. Signed-off-by:
