am335x: spi driver and two chip select

[Micka <mickamusset@xxxxxxxxx>]

Hi,

I've two MAX3107 connected to the spi 1 line. ( chip select 0 and 1 )

The problem is that when the spi driver start the probe function of
the driver, the chip select of the second max3107 is set to low .....

During the first call of the probe function, the driver try to read a
register on the first device, but because of the second chip select
set to low, the two device answer at the same time .... I don't really
understand why ?

I've correctly configured the CS1 and CS0 to be set as an output with
a pull up ....


&spi1{
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&bb_spi1_pins>;
status = "okay";
ti,pindir-d0-out-d1-in;

max3107a: max3107a@0 {
 compatible = "maxim,max3107";
 reg = <0>;
 clock-frequency = <1843200>;
 interrupt-parent = <&gpio1>;
 interrupts =<7 IRQ_TYPE_EDGE_FALLING>;
 gpio-controller;
 spi-max-frequency = <4000000>;
 status = "okay";
};

max3107b: max3107b@1 {
compatible = "maxim,max3107";
reg = <1>;
clock-frequency = <1843200>;
interrupt-parent = <&gpio2>;
interrupts=<5 IRQ_TYPE_EDGE_FALLING>;
spi-max-frequency = <4000000>;
status = "okay";
};

};
