    BCM270X_DT: Set spidev spi-max-frequency to 125MHz
    
    The BCM2835 SPI controllers have a maximum bus clock of half the system
    clock speed, so with the 250MHz system clock found on Raspberry Pis
    you get a theoretical maximum bus speed of 125MHz. Note that this
    speed is unlikely to be reliable, and the maximum usable bus spee will
    depend on both the attached device and the wiring.
    
    See: raspberrypi/linux#2165
