But here you can have subnodes, no? These could then be just
enumerated as usual.
&mikrobus_board {
mikrobus_gpio: gpio {
gpio-controller;
#gpio-cells = <1>;
};
spi {
cs-gpios = <&mikrobus_gpio 1>;
spi@0 {
compatible = "mydevice";
reg = <0>;
};
};
};
Hi, I am now working on an approach for mikroBUS based on the apprach
described here: [1]
I am thinking of the gpio-controller approach you seem to have used
here. So I wanted to inquire if there already exists a gpio-controller
driver that can create a proxy controller that forwards stuff to the
underlying actual controller. So something like the following:
&mikrobus_gpio: gpio {
gpio-controller;
#gpio-cells = <2>;
gpios = <&gpio1 0>, <&gpi2 1>;
};
spi {
cs-gpios = <&mikrobus_gpio 1 GPIO_ACTIVE_HIGH>;
};
There does exist gpio0-virtio, but that seems to be for vm context.
