You can find it at -`util/gpios_to_zephyr_dts.c`, and instructions are in the file on how -to compile and use it. You may have to hand-modify the output. - -The resultant CL for Lazor can be found [here](https://crrev.com/c/2749768). - -## Bring up Host Commands - -Set `CONFIG_PLATFORM_EC_HOSTCMD=y` and enable the appropriate -host-command interface for your platform (e.g., eSPI). - -An example CL for Lazor can be found [here](https://crrev.com/c/2749428). - -As long as you get this compiling that should be enough to move to the -next step.
