Agreed, I would prefer that as well: But unfortunately I will not be able to add dynamic calculation right now. Best regards, Alexander

Okay, just wanted to ask if someone (maybe TQ) has the time to implement and test it. Regards, Marco
Hi, this series adds LVDS display support for TQMa93xxLA/MBa93xxLA. It consists of two parts: 1. LVDS support for imx93 2. LVDS platform support for tqma9352-mba93xxla Patch 1 is the imx93 equivalent of commit 9cb6d1b39a8f ("soc: imx: imx8m-blk-ctrl: Scan subnodes and bind drivers to them") Patch 2 is the imx93 equivalent of commit 1cb0c87d27dc ("dt-bindings: soc: imx8mp-media-blk-ctrl: Add LDB subnode into schema and example") Patch 3 is the imx93 equivalent of commit 94e6197dadc9 ("arm64: dts: imx8mp: Add LCDIF2 & LDB nodes") Patch 4 adds a video PLL configuration for 477.4MHz Patch 5 adds LVDS DT overlay for platform support Patches 1-3 are self-contained from patches 4-5 and could be merged independently. Patch 4 is necessary to achieve a correct LVDS frequency supported by the display.
