Subject: [PATCH v2 1/3] dt-bindings: arm: qcom: Add Asus Zenbook A14 UX3407QA LCD/OLED variants
Date: Fri, 26 Sep 2025 09:08:52 +0200 [thread overview]
Message-ID: <20250926-zenbook-improvements-v2-1-c0b512ab6b57@vinarskis.com> (raw)
In-Reply-To: <20250926-zenbook-improvements-v2-0-c0b512ab6b57@vinarskis.com>
X1/X1 Plus variant of the said device comes in either FHD+ OLED or FHD+
LCD panel, and shares the same model number UX3407QA. It appears LCD
panel's brightness adjustment is PWM backlight controlled, so a
dedicated device-tree is required. Introduce dedicated compatibles with
fallback to 'asus,zenbook-a14-ux3407qa' as they are otherwise the same.
