WebSep 20, 2024 · With pinctrl we don’t necessarily touch the i2c node–it is instead given the address of a pinctrl nodelabel. The pinctrl-state nodes are where actual pins are specified, using a syntax that might look like &i2c1_sda_gpio33. (The exact format of pin addressing varies by vendor. We’ll discuss how to look up that info.) Webcompatible represents the name of the SPI device driver. reg represents the index of the gpio chip select associated to this SPI device. spi-max-frequency represents the maximum SPI clocking speed for the device (in Hz).
