Subject: [PATCH 1/2] dt-bindings: pwm: Add T-HEAD PWM controller
Date: Fri, 29 Sep 2023 01:02:53 +0800	[thread overview]
Message-ID: <20230928170254.413-2-jszhang@kernel.org> (raw)
In-Reply-To: <20230928170254.413-1-jszhang@kernel.org>

T-HEAD SoCs such as the TH1520 contain a PWM controller used
among other things to control the LCD backlight, fan and so on.
