14 DB8500 digital baseband system-on-chip and its siblings such as
16 itself, not off-chip clocks. There are four different on-chip
17 clocks - RTC (32 kHz), CPU clock (SMP TWD), PRCMU (power reset and
18 control management unit) clocks and PRCC (peripheral reset and
19 clock controller) clocks. For some reason PRCC 4 does not exist so
