An AMBA device will be probed once two things have occured: 1) ACPI has registered a device, and 2) the driver has registered itself as an AMBA driver. Since several drivers register themselves very early on, the probe will happen as soon as ACPI registers the device. If a device depends on a clock, the clock must be probed before ACPI registers the device. This means that the clock definition must be encountered first in the DSDT file, and the clock driver must already be loaded when this happens. There are other potential solutions, with this solution registering the clock driver very early in the boot process to avoid changes to other drivers.
