| 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: | ||

| 41 | * To avoid AB-BA locking problems, locks must always be traversed from child | ||

| 46 | * which attemps to iterate through the entire list of clocks and take every | ||
| 47 | * clock lock. If any call to spin_trylock fails, all locked clocks are | ||
| 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 | ||
| 52 | * on itself, except for clk_get_rate_locked and clk_set_rate_locked. Any | ||

| 26 | * | ||
| 27 | * In a proper cascaded interrupt controller, the interrupt lines with | ||
| 28 | * cascaded interrupt controllers on them are just normal interrupt lines. | ||
