    ARM: bcm281xx: Add timer driver (driver portion) · 8011657b
    Christian Daudt authored
    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).
