1 | BCM2835 Top-Level ("ARMCTRL") Interrupt Controller | ||
2 | |||
3 | The BCM2835 contains a custom top-level interrupt controller, which supports | ||
4 | 72 interrupt sources using a 2-level register scheme. The interrupt | ||
5 | controller, or the HW block containing it, is referred to occasionally | ||
6 | as "armctrl" in the SoC documentation, hence naming of this binding. | ||
7 | |||
8 | Required properties: | ||
9 | |||
10 | - compatible : should be "brcm,bcm2835-armctrl-ic.txt" | ||
11 | - reg : Specifies base physical address and size of the registers. | ||
12 | - interrupt-controller : Identifies the node as an interrupt controller | ||
13 | - #interrupt-cells : Specifies the number of cells needed to encode an | ||
14 | interrupt source. The value shall be 2. | ||
15 | |||
16 | The 1st cell is the interrupt bank; 0 for interrupts in the "IRQ basic | ||
17 | pending" register, or 1/2 respectively for interrupts in the "IRQ pending | ||
18 | 1/2" register. | ||
19 | |||
20 | The 2nd cell contains the interrupt number within the bank. Valid values | ||
21 | are 0..7 for bank 0, and 0..31 for bank 1. | ||
22 | |||
23 | The interrupt sources are as follows: | ||

1 | BCM2835 System Timer | ||
2 | |||
3 | The System Timer peripheral provides four 32-bit timer channels and a | ||
4 | single 64-bit free running counter. Each channel has an output compare | ||
5 | register, which is compared against the 32 least significant bits of the | ||
6 | free running counter values, and generates an interrupt. | ||

48 | * unlocked, and the process is retried. When all the locks are held, | ||
49 | * the only clock operation that can be called is clk_get_rate_all_locked. | ||
50 | * | ||
51 | * Within a single clock, no clock operation can call another clock operation | ||

16 | * | ||
17 | * If an interrupt fires on bank 1 that isn't in the shortcuts list, bit 8 | ||

26 | * | ||
27 | * In a proper cascaded interrupt controller, the interrupt lines with | ||
28 | * cascaded interrupt controllers on them are just normal interrupt lines. | ||
29 | * You can mask the interrupts and get on with things. With this controller | ||
30 | * you can't do that. | ||
31 | * | ||
32 | * Quirk 3: The shortcut interrupts can't be (un)masked in bank 0 | ||
33 | * | ||
34 | * Those interrupts that have shortcuts can only be masked/unmasked in | ||
35 | * their respective banks' enable/disable registers. Doing so in the bank 0 | ||

41 | * Bits 8+: Unused | ||
