Description
The count between clock stretches
The count to use to automatically wake-up the MMIO and processor
clocks. The register is a 32-bit register with the two LSB bit hard-
coded to zero. If the CLK_WAKEUP_CTL register is written with a
value of 0x0000_0008. Then the wake-up count will be set to a
count value of 8. This means that the lowest count value is 4
(0x0000_0004 written to the CLK_WAKEUP_CTL register)
Enables the use of pin GPIO[15] as a wake-up event.
Enables the use of the GPIO interrupt as an wake-up event.
The total time to count clock edges
Signifies that the count is done

The result of the count of the clock frequency counting.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
Adjust the aligner for fgpo out (VDO_CLK2)
Note: this clock can not have latency added to it.
Adjust the aligner for the clock going to area 3
Adjust the aligner for fgpo out internal clock
Adjust the aligner for qvcp out internal clock
Adjust the aligner for qvcp pix clock
Adjust the aligner for qvcp out (VDO_CLK1)
Adjust the aligner for the clock going to area 7
Adjust the aligner for the clock going to area 6
