Hi,
On my board we use pins of uart0 for the spi interface ( all others pins are used ) .
To do so, we deactivate the max310x by default, but when the linux boot, it has to move a gpio to enable the device. I modified the spi driver to detect the parameter : enable-gpio = <&gpio1 3 GPIO_ACTIVE_LOW>;
also we used the max310x with an external clock, so we don’t need a clock node. To do so, I modified the driver max310x to detect the parameter: clock-frequency = <1843200>; .
And it works well !
