Thank you so much, you made my day! Sorry, I didn't see the alias was
used different.
Although my credibility gambled away I think I found a real bug in EQOS
driver with fixed-phy:
In file fixed.c in in function fixedphy_config() the call
val = ofnode_read_u32_default(node, "speed", 0);
returns 0 instead of 1000 and also the duplex is not set. I found that
in file/function dwc_eth_qos.c / eqos_start() the line
eqos->phy->node = eqos->phy_of_node;
is reponsible for losing the info. Don't know what magic happens here -
so I can't fix it - just followed the data. So all works well and even
the parsing of old and new fixed-link devicetree works til that line.
After that I don't get speed anymore. Can someone please confirm?
Best regards,
Elmar

Hello, kindly ask for help about SPI at an IMX8MP. I tried latest

sspi command returns: Invalid bus 0
Could you try passing an aliases entry in your dts like this?
aliases {
spi0 = &ecspi1;
};
Does this help?
What am I doing wrong or is this a bug? Thanks ahead for any hint.
dt: (tested with both types of cs-gpios)
&ecspi1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi1>;
cs-gpios = <0>, <&gpio5 9 GPIO_ACTIVE_LOW>;
// cs-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>;
This last format is the correct one.
