Subject: [PATCH v2 1/2] dt-bindings: hwmon: Add AST2700 compatible
Date: Tue, 18 Nov 2025 17:11:53 +0800 [thread overview]
Message-ID: <20251118-upstream_pwm_tach-v2-1-4d9bc13d34f9@aspeedtech.com> (raw)
In-Reply-To: <20251118-upstream_pwm_tach-v2-0-4d9bc13d34f9@aspeedtech.com>
Adds support for the AST2700 PWM/Tach controller by extending the
compatible string enumeration in the device tree binding.
The AST2700 PWM/Tach hardware is compatible with the existing binding
schema and requires no additional properties or modifications beyond
the new compatible string.
