Subject: [PATCH v4 1/2] dt-bindings: pwm: dwc: add reset optional
Date: Wed, 15 Apr 2026 17:50:20 +0800 [thread overview]
Message-ID: <20260415095020.1597-1-dongxuyang@eswincomputing.com> (raw)
In-Reply-To: <20260415094908.1539-1-dongxuyang@eswincomputing.com>
From: Xuyang Dong <dongxuyang@eswincomputing.com>
The DesignWare PWM includes separate reset signals dedicated to each clock
domain:
The presetn signal resets logic in pclk domain.
The timer_N_resetn signal resets logic in the timer_N_clk domain.
The resets are active-low.
