commit e47cb97f153193d4b41ca8d48127da14513d54c7 upstream.
The Clock Pulse Generator (CPG) device node lacks the extal2 clock. This may lead to a failure registering the "r" clock, or to a wrong parent for the "usb24s" clock, depending on MD_CK2 pin configuration and boot loader CPG_USBCKCR register configuration.
This went unnoticed, as this does not affect the single upstream board configuration, which relies on the first clock input only.
