Subject: [PATCH v2 2/3] arm64: dts: qcom: Rework X1-based Asus Zenbook A14's displays
Date: Fri, 26 Sep 2025 09:08:53 +0200 [thread overview]
Message-ID: <20250926-zenbook-improvements-v2-2-c0b512ab6b57@vinarskis.com> (raw)
In-Reply-To: <20250926-zenbook-improvements-v2-0-c0b512ab6b57@vinarskis.com>
The laptop comes in two variants:
* UX3407RA, higher end, FHD+ OLED or WOXGA+ OLED panels
* UX3407QA, lower end, FHD+ OLED or FHD+ LCD panels
Even though all three panels work with "edp-panel", unfortunately the
brightness adjustmenet of LCD panel is PWM based, requiring a dedicated
device-tree. Convert "x1p42100-asus-zenbook-a14.dts" into ".dtsi" to
allow for this split, introduce new LCD variant. Leave current variant
without postfix and with the unchanged model name, as some distros
(eg. Ubuntu) rely on this for automatic device-tree detection during
kernel installation/upgrade.
As dedicated device-tree is required, update compatibles of OLED
variants to correct ones. Keep "edp-panel" as fallback, since it is
enough to make the panels work.
While at it moving .dts, .dtsi around, drop 'model' from the top level
x1-asus-zenbook-a14.dtsi as well.
