7 title: Samsung Exynos SoC Multi Core Timer (MCT)
10 - Krzysztof Kozlowski <krzk@kernel.org>
13 The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
14 global timer and CPU local timers. The global timer is a 64-bit free running
15 up-counter and can generate 4 interrupts when the counter reaches one of the
16 four preset counter values. The CPU local timers are 32-bit free running
17 down-counters and generate an interrupt when the counter expires. There is
18 one CPU local timer instantiated in MCT for every CPU in the system.

64 Interrupts should be put in specific order. This is, the local timer
65 interrupts should be specified after the four global timer interrupts
67 0: Global Timer Interrupt 0
68 1: Global Timer Interrupt 1
69 2: Global Timer Interrupt 2
70 3: Global Timer Interrupt 3
71 4: Local Timer Interrupt 0
72 5: Local Timer Interrupt 1

76 For MCT block that uses a per-processor interrupt for local timers, such
77 as ones compatible with "samsung,exynos4412-mct", only one local timer
