12 * the clock control units (CCUs) on Broadcom BCM281XX family SoCs.
16 * These are the bcm281xx CCU device tree "compatible" strings.
17 * We're stuck with using "bcm11351" in the string because wild
18 * cards aren't allowed, and that name was the first one defined
19 * in this family of devices.
