Merge tag 'clksrc-cleanup-for-3.10-part2' of git://sources.calxeda.com/kernel/linux into late/clksrc
This is the 2nd part of ARM timer clean-ups for 3.10. This series has the following changes: - Add sched_clock selection logic to select the highest frequency clock - Use full 64-bit arch timer counter for sched_clock - Convert arch timer, sp804 and integrator-cp timers to CLKSRC_OF and adapt all users to use clocksource_of_init * tag 'clksrc-cleanup-for-3.10-part2' of git://sources.calxeda.com/kernel/linux: devtree: add binding documentation for sp804 ARM: integrator-cp: convert use CLKSRC_OF for timer init ARM: versatile: use OF init for sp804 timer ARM: versatile: add versatile dtbs to dtbs target ARM: vexpress: remove extra timer-sp control register clearing ARM: dts: vexpress: disable CA9 core tile sp804 timer ARM: vexpress: remove sp804 OF init ARM: highbank: use OF init for sp804 timer ARM: timer-sp: convert to use CLKSRC_OF init OF: add empty of_device_is_available for !OF ARM: convert arm/arm64 arch timer to use CLKSRC_OF init ARM: make machine_desc->init_time default to clocksource_of_init ARM: arch_timer: use full 64-bit counter for sched_clock ARM: make sched_clock just call a function pointer ARM: sched_clock: allow changing to higher frequency counter Signed-off-by: Olof Johansson <olof@lixom.net> This has a nasty set of conflicts with the exynos MCT code, which was moved in a separate branch, and then fixed up when merged in, but still conflicts a bit here. It should have been sorted out by this merge though.

1ARM sp804 Dual Timers
2---------------------------------------
3
4Required properties:
5- compatible: Should be "arm,sp804" & "arm,primecell"
6- interrupts: Should contain the list of Dual Timer interrupts. This is the
7 interrupt for timer 1 and timer 2. In the case of a single entry, it is
8 the combined interrupt or if "arm,sp804-has-irq" is present that
9 specifies which timer interrupt is connected.
10- reg: Should contain location and length for dual timer register.
11- clocks: clocks driving the dual timer hardware. This list should be 1 or 3
12 clocks. With 3 clocks, the order is timer0 clock, timer1 clock,
13 apb_pclk. A single clock can also be specified if the same clock is
14 used for all clock inputs.
15
16Optional properties:
17- arm,sp804-has-irq = <#>: In the case of only 1 timer irq line connected, this
18 specifies if the irq connection is for timer 1 or timer 2. A value of 1
19 or 2 should be used.
20
21Example:
22
23 timer0: timer@fc800000 {
24 compatible = "arm,sp804", "arm,primecell";
25 reg = <0xfc800000 0x1000>;
26 interrupts = <0 0 4>, <0 1 4>;
27 clocks = <&timclk1 &timclk2 &pclk>;
28 clock-names = "timer1", "timer2", "apb_pclk";
29 };
