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
|
|
|
|
Required properties:
|
|
- compatible : "bcm,kona-timer"
|
|
- reg : Register range for the timer
|
|
- interrupts : interrupt for the timer
|
|
- clock-frequency: frequency that the clock operates
|
|
|
|
Example:
|
|
timer@35006000 {
|
|
compatible = "bcm,kona-timer";
|
|
reg = <0x35006000 0x1000>;
|
|
interrupts = <0x0 7 0x4>;
|
|
clock-frequency = <32768>;
|
|
};
