Previously there was: "interrupts = <14 IRQ_TYPE_EDGE_FALLING>;", meaning the IRQ triggers on the edge "1 -> 0". It doesn't look correct, if you say now there is an IRQ at level "1". > + spi-max-frequency = <10000000>; > + }; > }; regards, Marc

Hi Fabio, Currently, the Ethernet cable is not connected, which is why it's showing that message. If I connect the Ethernet cable, it will give a log like this: [ 12.670384] fec 30be0000.ethernet eth0: Link is Down [ 14.719222] fec 30be0000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx Regards, Tarang

Add following peripherals support for the Emtop i.MX8M Mini Baseboard * Wi-Fi * Audio * SD card * RTC * CAN bus * USB OTG Signed-off-by: Tarang Raval <tarang.raval@siliconsignals.io> --- Changes in v2: 1. Updated the node name and pinctrl name. 2. Removed the 'regulators' container. 3. Removed a stray blank line. 4. Removed non-existent properties. 5. Removed unused node and pinctrl: -modem-reset -pinctrl_uart1 6. Defined the CAN transceiver reset GPIO separately. Change in v3: 1. Removed 'can-connector'. 2. Use USB connector instead of extcon_usb. 3. Changed id-gpio to id-gpios. 4. Use Level trigger IRQ in the CAN node. 5. Corrected the compatible property of RTC. 6. Added blank lines to separate the pinctrl groups. --- .../dts/freescale/imx8mm-emtop-baseboard.dts | 326 ++++++++++++++++++ 1 file changed, 326 insertions(+)
