Nope. "samsung,exynos5250-pmu" is the specific device (or hardware programming interface) this device is compatible with. With class I mean the generic kind of device, such as system-controller, i2c, pinctrl, display, etc., as specified by sections 2.2.1 and 2.2.2 of ePAPR. Anyway, node names are just a matter of coding style, as they don't have any semantical meaning in most cases (such as this one). > It is also compatible with the generic "syscon" class of devices. It is also compatible with the generic "syscon" programming interface, which represents a set of loosely related registers that control various aspects of other IP blocks.
