Hi,
I have a board based on A20-OLinuXino-LIME2-eMMC, and I'm trying to do a
SPI communication to work(max11043), but under mainline does not work. It
works on linux sunxi-3.4, though.
Dts code:
&spi1 {
pinctrl-names = "default";
pinctrl-0 = <&spi1_pins_a>,
<&spi1_cs0_pins_a>;
status = "okay";
max11043: max11043@0 {
compatible = "maxim,max11043";
reg = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_max_cnvst>;
convrun-gpios = <&pio 7 25 GPIO_ACTIVE_LOW>; //PH25
pinctrl-1 = <&pinctrl_max_eoc>;
interrupt-parent = <&pio>;
interrupts = <7 21 IRQ_TYPE_EDGE_FALLING>; //EINT21(PH21)
spi-max-frequency = <10000000>;
};
};
pinctrl_max_cnvst: pinctrl_max_cnvst@0 {
pins = "PH25";
function = "gpio_out";
};
pinctrl_max_eoc: pinctrl_max_eoc@0 {
pins = "PH21";
function = "gpio_in";
};
The output I got when running on linux sunxi-3.4 is:
write: 20 40 80
read: 20 40 80
But in mainline is not ok, the output is:
write: 20 40 80
read: 81 00 00
Any ideas or help are appreciated. Thanks,
Vini
