ARM: bcm281xx: Add timer driver (DT 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).

Broadcom Kona Family timer
-----------------------------------------------------
This timer is used in the following Broadcom SoCs:
BCM11130, BCM11140, BCM11351, BCM28145, BCM28155

ARM: DT: binding fixup to align with vendor-prefixes.txt (DT) [ this is a follow-up to this discussion: http://archive.arm.linux.org.uk/lurker/message/20130730.230827.a1ceb12a.en.html ] This patchset renames all uses of "bcm," name bindings to "brcm," as they were done prior to knowing that brcm had already been standardized as Broadcom vendor prefix (in Documentation/devicetree/bindings/vendor-prefixes.txt). This will not cause any churn on devices because none of these bindings have made it into production yet. Also rename the the following dt binding docs that had "bcm," in their name for consistency: - bcm,kona-sdhci.txt -> kona-sdhci.txt - bcm,kona-timer.txt -> kona-timer.txt Signed-off-by: Christian Daudt <csd@broadcom.com> Acked-by: Stephen Warren <swarren@nvidia.com>
