Add support for generic BCM SoC chipsets In order to start upstreaming Broadcom SoC support, create a starting hierarchy, arch and dts files. The first support SoC family that is planned is the BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile SoC cores. This code is just the skeleton code for get the machine upstreamed. It has been made MULTIPLATFORM compatible. Next steps ---------- Upstream a basic set of drivers - sufficient for a console boot to ramdisk. These will includer timer, gpio, i2c drivers. After this basic set, we will proceed with a more comprehensive set of drivers for the 281XX SoC family. v2 patch mods -------- - Remove l2x0_of_init call as there were problems with the code. A separate patch will be submitted with cache init code - Rename capri files and refs to bcm281xx-based names - Add bcm281xx binding doc - various misc cleanups v3 patch mods ------------- - Remove extra #include lines - Remove remaining references to capri - dt uart chipset string added - cleaned up chip # references v4 patch mods ------------- - swap order of compatible definitions for uart - fix typo v5 patch mods ------------- - Rename bcm281xx to bcm11351 in dts+code, leaving references to bcm281xx only in help+comments. v6 patch mods ------------- - fix typo in uart 'compatible' string Signed-off-by: Christian Daudt <csd@broadcom.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>

ARM: bcm281xx: Add timer driver (driver portion) This adds support for the Broadcom timer, used in the following SoCs: BCM11130, BCM11140, BCM11351, BCM28145, BCM28155 Updates from V6: - Split DT portion into a separate patch Updates from V5: - Rebase to latest arm-soc/for-next Updates from V4: - Switch code to use CLOCKSOURCE_OF_DECLARE Updates from V3: - Migrate to 3.9 timer framework updates Updates from V2: - prepend static fns + fields with kona_ Updates from V1: - Rename bcm_timer.c to bcm_kona_timer.c - Pull .h into bcm_kona_timer.c - Make timers static - Clean up comment block - Switched to using clockevents_config_and_register - Added an error to the get_timer loop if it repeats too much - Added to Documentation/devicetree/bindings/arm/bcm/bcm,kona-timer.txt - Added missing readl to timer_disable_and_clear Note: bcm,kona-timer was kept as the 'compatible' field to make it specific enough for when there are multiple bcm timers (bcm,timer is too generic).

This enables support for system based on Broadcom SoCs.
It currently supports the 'BCM281XX' family, which includes
BCM11130, BCM11140, BCM11351, BCM28145 and
BCM28155 variants.
