Subject: [PATCH v2 11/12] arm64: dts: allwinner: h616: add LCD and LVDS pins
Date: Sun, 20 Jul 2025 20:48:49 +1200 [thread overview]
Message-ID: <20250720085047.5340-12-ryan@testtoast.com> (raw)
In-Reply-To: <20250720085047.5340-1-ryan@testtoast.com>
The Allwinner H616 (and its H618, H700 and T507 package variants with
the same die) have 28 video output pins for RGB/SPI and LVDS display.
These are in GPIO Bank D and are multiplexed.
In RGB mode, pins PD0-PD23 are for 24-bit RGB pixel output, pins
PD24-PD27 are for clock, DE, HSYNC and VSYNC.
In LVDS mode, pins PD0-PD9 are for LVDS0 and pins PD10-19 for LVDS1, and
can be configured by the H616 display engine for either one high-
resolution (dual link) or two low resolution displays.
Add device tree nodes for the LCD and LVDS pins.
