+/*
+ * This is the device driver for the MPC5200 interrupt controller.
+ *
+ * hardware overview
+ * -----------------
+ * The MPC5200 interrupt controller groups the all interrupt sources into
+ * three groups called 'critical', 'main', and 'peripheral'. The critical
+ * group has 3 irqs, External IRQ0, slice timer 0 irq, and wake from deep
+ * sleep. Main group include the other 3 external IRQs, slice timer 1, RTC,
+ * gpios, and the general purpose timers. Peripheral group contains the
+ * remaining irq sources from all of the on-chip peripherals (PSCs, Ethernet,
+ * USB, DMA, etc).
+ *
+ * virqs
+ * -----
+ * The Linux IRQ subsystem requires that each irq source be assigned a
+ * system wide unique IRQ number starting at 1 (0 means no irq). Since
+ * systems can have multiple interrupt controllers, the virtual IRQ (virq)
+ * infrastructure lets each interrupt controller to define a local set
+ * of IRQ numbers and the virq infrastructure maps those numbers into
+ * a unique range of the global IRQ# space.
+ *
+ * To define a range of virq numbers for this controller, this driver first
+ * assigns a number to each of the irq groups (called the level 1 or L1
+ * value). Within each group individual irq sources are also assigned a
+ * number, as defined by the MPC5200 user guide, and refers to it as the
+ * level 2 or L2 value. The virq number is determined by shifting up the
+ * L1 value by MPC52xx_IRQ_L1_OFFSET and ORing it with the L2 value.
+ *
+ * For example, the TMR0 interrupt is irq 9 in the main group. The
+ * virq for TMR0 is calculated by ((1 << MPC52xx_IRQ_L1_OFFSET) | 9).
+ *
+ * The observant reader will also notice that this driver defines a 4th
+ * interrupt group called 'bestcomm'. The bestcomm group isn't physically
+ * part of the MPC5200 interrupt controller, but it is used here to assign
+ * a separate virq number for each bestcomm task (since any of the 16
+ * bestcomm tasks can cause the bestcomm interrupt to be raised). When a
+ * bestcomm interrupt occurs (peripheral group, irq 0) this driver determines
+ * which task needs servicing and returns the irq number for that task. This
+ * allows drivers which use bestcomm to define their own interrupt handlers.
+ *
+ * irq_chip structures
+ * -------------------
+ * For actually manipulating IRQs (masking, enabling, clearing, etc) this
+ * driver defines four separate 'irq_chip' structures, one for the main
+ * group, one for the peripherals group, one for the bestcomm group and one
+ * for external interrupts. The irq_chip structures provide the hooks needed
+ * to manipulate each IRQ source, and since each group is has a separate set
+ * of registers for controlling the irq, it makes sense to divide up the
+ * hooks along those lines.
+ *
+ * You'll notice that there is not an irq_chip for the critical group and
+ * you'll also notice that there is an irq_chip defined for external
+ * interrupts even though there is no external interrupt group. The reason
+ * for this is that the four external interrupts are all managed with the same
+ * register even though one of the external IRQs is in the critical group and
+ * the other three are in the main group. For this reason it makes sense for
+ * the 4 external irqs to be managed using a separate set of hooks. The
+ * reason there is no crit irq_chip is that of the 3 irqs in the critical
+ * group, only external interrupt is actually support at this time by this
+ * driver and since external interrupt is the only one used, it can just
+ * be directed to make use of the external irq irq_chip.
+ *
+ * device tree bindings
+ * --------------------
+ * The device tree bindings for this controller reflect the two level
+ * organization of irqs in the device. #interrupt-cells = <3> where the
+ * first cell is the group number [0..3], the second cell is the irq
+ * number in the group, and the third cell is the sense type (level/edge).
+ * For reference, the following is a list of the interrupt property values
+ * associated with external interrupt sources on the MPC5200 (just because
+ * it is non-obvious to determine what the interrupts property should be
+ * when reading the mpc5200 manual and it is a frequently asked question).
+ *
+ * External interrupts:
+ * <0 0 n> external irq0, n is sense (n=0: level high,
+ * <1 1 n> external irq1, n is sense n=1: edge rising,
+ * <1 2 n> external irq2, n is sense n=2: edge falling,
+ * <1 3 n> external irq3, n is sense n=3: level low)
