+Broadcom BCM2835 device tree bindings
+-------------------------------------------
+
+Boards with the BCM2835 SoC shall have the following properties:
+
+Required root node property:
+
+compatible = "brcm,bcm2835";
--- /dev/null
+BCM2835 Top-Level ("ARMCTRL") Interrupt Controller
+
+The BCM2835 contains a custom top-level interrupt controller, which supports
+72 interrupt sources using a 2-level register scheme. The interrupt
+controller, or the HW block containing it, is referred to occasionally
+as "armctrl" in the SoC documentation, hence naming of this binding.
+
+Required properties:
+
+- compatible : should be "brcm,bcm2835-armctrl-ic.txt"
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 2.
+
+ The 1st cell is the interrupt bank; 0 for interrupts in the "IRQ basic
+ pending" register, or 1/2 respectively for interrupts in the "IRQ pending
+ 1/2" register.
+
+ The 2nd cell contains the interrupt number within the bank. Valid values
+ are 0..7 for bank 0, and 0..31 for bank 1.
+
+The interrupt sources are as follows:
+
+Bank 0:
+0: ARM_TIMER
+1: ARM_MAILBOX
+2: ARM_DOORBELL_0
+3: ARM_DOORBELL_1
+4: VPU0_HALTED
+5: VPU1_HALTED
+6: ILLEGAL_TYPE0
+7: ILLEGAL_TYPE1
+
+Bank 1:
+0: TIMER0
+1: TIMER1
+2: TIMER2
+3: TIMER3
+4: CODEC0
+5: CODEC1
+6: CODEC2
+7: VC_JPEG

+26: DMA10
+27: DMA11
+28: DMA12
+29: AUX
+30: ARM
+31: VPUDMA
+
+Bank 2:
+0: HOSTPORT
+1: VIDEOSCALER
+2: CCP2TX
+3: SDC
+4: DSI0
+5: AVE
+6: CAM0
+7: CAM1
+8: HDMI0
+9: HDMI1
+10: PIXELVALVE1
+11: I2CSPISLV
+12: DSI1
+13: PWA0

+17: GPIO0

+26: SLIMBUS
+27: VEC
+28: CPG

+30: VC_ARASANSDIO

+
+Example:
+
+intc: interrupt-controller {
+ compatible = "brcm,bcm2835-armctrl-ic";
+ reg = <0x7e00b200 0x200>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+};

+BCM2835 System Timer
+
+The System Timer peripheral provides four 32-bit timer channels and a
+single 64-bit free running counter. Each channel has an output compare
+register, which is compared against the 32 least significant bits of the
+free running counter values, and generates an interrupt.
+
+Required properties:
+
+- compatible : should be "brcm,bcm2835-system-timer.txt"
+- reg : Specifies base physical address and size of the registers.
+- interrupts : A list of 4 interrupt sinks; one per timer channel.
+- clock-frequency : The frequency of the clock that drives the counter, in Hz.
+
+Example:
+
+timer {
+ compatible = "brcm,bcm2835-system-timer";
+ reg = <0x7e003000 0x1000>;
+ interrupts = <1 0>, <1 1>, <1 2>, <1 3>;
+ clock-frequency = <1000000>;

* Locking:
*
- * Each struct clk has a spinlock.
- *
- * To avoid AB-BA locking problems, locks must always be traversed from child
- * clock to parent clock. For example, when enabling a clock, the clock's lock
- * is taken, and then clk_enable is called on the parent, which take's the
- * parent clock's lock. There is one exceptions to this ordering: When dumping
- * the clock tree through debugfs. In this case, clk_lock_all is called,
- * which attemps to iterate through the entire list of clocks and take every
- * clock lock. If any call to spin_trylock fails, all locked clocks are
- * unlocked, and the process is retried. When all the locks are held,
- * the only clock operation that can be called is clk_get_rate_all_locked.
- *
- * Within a single clock, no clock operation can call another clock operation
- * on itself, except for clk_get_rate_locked and clk_set_rate_locked. Any
- * clock operation can call any other clock operation on any of it's possible
- * parents.
- *
* An additional mutex, clock_list_lock, is used to protect the list of all
* clocks.
*
- * The clock operations must lock internally to protect against
- * read-modify-write on registers that are shared by multiple clocks

+ * you can't do that.

+ * Bits 0-6: IRQ (index in order of interrupts from banks 1, 2, then 0)
