Hi
I have in device tree node:
qspi: somename@0 {
compatible = "nameOfDriverFrom/drivers/spi";
reg = <someAddr size>;
clocks = <reference to clock>;
clock-names = "some names";
#address-cells = <1>;
#size-cells = <0>;
status = "disabled";
};
and then I have such thing:
&qspi {
pinctrl-names="default";
pinctrl-0 = <&reference to some pin controller>;
status = "okay";
spi-max-frequency = <11000000>;
flash@0 {
compatible = "spi-flash (this is driver from /drivers/mtd/)";
#address-cells = <1>;
#size-cells = <1>;
reg = <0x0>;
spi-max-frequency = <22000000>;
};
};
Why just one node isn't enough? And what frequency driver have at all -
11MHz or 22MHz?
What is the difference between drivers defined in /drivers/spi and
/drivers/mtd?
Does it mean that driver in /drivers/mtd can use somehow driver or the code
from /drivers/spi?
Or maybe it works in opposite direction?
