It configures the platform-specific peripherals and aliases for OpenBMC usage. The series is comprised of two patches: 1. Adds the compatible string for the board to the binding documentation. 2. Adds the main Device Tree Source file for the Anacapa BMC. Changes in v8: * Dropped the unused 'pcc_memory' reserved memory region as suggested by Andrew Jeffery. * Reordered the 'spi-gpio' properties to group all '-gpios' properties together for better readability (Andrew Jeffery). * Moved the 'pinctrl_ncsi3_default' pinctrl group from the board DTS file to 'arch/arm/boot/dts/aspeed-g6.dtsi' (assuming this dtsi change is applied separately or already in the base) to make it available for other platforms (Andrew Jeffery). * Revised the 'gpio-line-names' for better clarity and alignment with schematic signal names, avoiding confusion with pin-muxed functions (Andrew Jeffery). * Improved the formatting and readability of 'sgpio-line-names' list. * Removed the unused 'led-2' definition from the 'leds' node. * Added support for the ADC128D818 sensor to the I2C bus. * No functional changes in the binding patch (1/2). * Added clarification for mixed-case signal names (Andrew Jeffery): The mixed-case names (e.g., FM_CPU0_SYS_RESET_N) in gpio-line-names are chosen to directly match the signal names used in the hardware schematics. This convention is used to maintain strict adherence and clarity when cross-referencing between the Device Tree and the board design documents.
