[RESEND PATCH v7 3/3] clocksource: Add clockevent support to NPS400 driver

From: Noam Camus Till now we used clockevent from generic ARC driver. This was enough as long as we worked with simple multicore SoC. When we are working with multithread SoC each HW thread can be scheduled to receive timer interrupt using timer mask register. This patch will provide a way to con

[RESEND PATCH v7 2/3] clocksource: update "fn" at CLOCKSOURCE_OF_DECLARE() of nps400 timer

From: Noam Camus nps_setup_clocksource() should take node as only argument as defined by typedef int (*of_init_fn_1_ret)(struct device_node *) Therefore need to replace: int __init nps_setup_clocksource(struct device_node *node, struct clk *clk) with int __init nps_setup_clocksource(struct devic

[RESEND PATCH v7 0/3] Add clockevent for timer-nps driver to NPS400 SoC

From: Noam Camus Change log --- V6 --> V7 Apply several comments made by Daniel Lezcano: 1) Remove CLOCK_EVT_FEAT_PERIODIC support. This way it is pure oneshot driver. This simplifies driver so that: nps_clkevent_add_thread() nps_clkevent_rm_thread() are more clearer without any vague logic i

[RESEND PATCH v7 1/3] soc: Support for NPS HW scheduling

From: Noam Camus This new header file is for NPS400 SoC (part of ARC architecture). The header file includes macros for save/restore of HW scheduling. The control of HW scheduling is achieved by writing core registers. This code was moved from arc/plat-eznps so it can be used from drivers/clockso
