hi,
The patches in the series are work in progress and as discussed with Al Stone and Hanjun include changes in the GTDT acpi table to add missing elements for ARM platforms. Elements added are Timer frequency, interrupt count(currently 8 supported), timer ID(This will be used to invoke the correct controller).
Still more TODO's are identified. * To add timer clock names. * if this __init invoking mechanism is finalised then other similar devices can use this like clock, GIC etc. * GTDT can ultimately be made CTDT(Common timer descriptor table) to other classes of timers like external exynos MCT.
Changes in V2: * Added new fields in GTDT acpi table. * Infrastructure to invoke the correct timer controller.
Thanks in advance. Amit
