Here's a slightly better diagram.

PMIC -> refclk provided to each (timer) element below.

MSM8994(timer) -- > USB
WD8a
               APBridgeA (timer) -> UniPro bus
               WD8a
                                            -> Module(timer) with UART
                                               WD1
                                            -> Module(timer) with GPIO
                                               WD2
                                            -> Module(timer) with blah
                                               WD3
                              -> SPI bus
                                            -> SVC(timer)
                                               Owns FrameTime
                                               GPIO {WD0...WDn}

So yes, each processor has it's own timer. We aren't trying to read the
MSM's FrameTime.
