Subject: [PATCH v13 1/2] Add DT bindings YAML schema for PWM fan controller of LGM SoC
Date: Tue, 15 Sep 2020 16:23:36 +0800 [thread overview]
Message-ID: <a5b9fefb58a6fe16964219b0d443bf81c58f5445.1600158087.git.rahul.tanwar@linux.intel.com> (raw)

In-Reply-To: <cover.1600158087.git.rahul.tanwar@linux.intel.com>
Intel's LGM(Lightning Mountain) SoC contains a PWM fan controller
which is only used to control the fan attached to the system. This
PWM controller does not have any other consumer other than fan.
Add DT bindings documentation for this PWM fan controller.
