- * P3: Translation from irq 0x0d to mask 0x2000 is for MrCoffee.

+ * The low 4 bits of the IRQ priority indicate the PIL, and the upper
+ * 4 bits indicate onboard vs. SBUS leveled vs. VME leveled. 0x20
+ * means onboard, 0x30 means SBUS leveled, and 0x40 means VME leveled.
+ *
+ * For example, an 'intr' IRQ priority value of 0x24 is onboard SCSI
+ * whereas a value of 0x33 is SBUS level 2. Here are some sample
+ * 'intr' property IRQ priority values from ss4, ss5, ss10, ss20, and
