From 6a96113107a9cf29b24f50b81f930508c0748fcd Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 8 Aug 2024 00:27:04 +0300 Subject: utils: codegen: gen-controls.py: Move helper classes to separate file The ControlEnum and Control helper classes defined in gen-controls.py are useful for other generator scripts. Move them to a separate file to make it possible to share them.
