/* Overview
*
* Per the schematic Adafruit Metro M4 Pro has one on-board crystal:
*
* X4 32.768KHz XOSC32
*
* However, I have been unsuccessful using it and have fallen back to using
* OSCULP32K(Unless CONFIG_METRO_M4_32KHZXTAL=y)
*
* Since there is no high speed crystal, we will run from the OSC16M clock
* source.
*
* OSC48M Output = 48Mhz
* |
* FDLL Input = 48MHz
* | Output = 48MHz
* GCLK5 Input = 48MHz
* | Output = 2MHz
* DPLL0 Input = 2MHz
* | Output = 120MHz
* GCLK0 Input = 120MHz
* | Output = 120MHz
* MCK Input = 120MHz
* | Output = 120MHz
* CPU Input = 120MHz
