/*
|
|
* We have two pin mux functions that must exist. First we need I2C0 to
|
|
* access the TPS65910 PMIC located on the M2 computing module.
|
|
* Second, if we want low-level debugging or a early UART (ie. before the
|
|
* pin controller driver is running), we need one of the UART ports UART0 to
|
|
* UART5 (usually UART3 since it is wired to K2).
|
|
* In case of I2C0 access we explicitly don't rely on the the ROM but we could
|
|
* do so as we use the primary mode (mode 0) for I2C0.
|
|
* All other multiplexing and pin configuration is done by the DT once it
|
|
* gets parsed by the pin controller driver.
|
|
* However we relay on the ROM to configure the pins of MMC0 (eMMC) as well
|
|
* as MMC1 (microSD card-cage) since these are our boot devices.
