How to enable CAN device driver on the STM32MP135F-DK

Hi

I plan to use CAN communication on the development board, but I have encountered some issues.

Modified stm32mp135f-dk.dts based on the instructions on the wiki.

However, the stm32mp13-pinctrl.dtsi file does not define the m_can2_pins_a and m_can2_sleep_pins_a nodes.

How should I specify the pins of CAN?

u should add &m_can2 {
clocks = <&scmi_clk CK_SCMI_HSE>, <&rcc FDCAN_K>;
};

Okay, clocks should indeed be added to the dts file, but how should I specify pinctrl-0 and pinctrl-1?

The stm32mp13-pinctrl.dtsi file does not define the m_can2_pins_a and m_can2_sleep_pins_a nodes

You should install openstlinux according to the link above, then configure CAN in stm32cubeide, then deploy to stm32mp1 board
