This 6-patch series adds LCD (XLCDC) and LVDS controller device tree nodes for the Microchip SAMA7D65 SoC, updates the LVDS binding, and enables relevant defconfig options. The series is straightforward but has a **critical functional issue**: the LCD controller DT node uses `compatible = "microchip,sama7d65-xlcdc"` without a fallback compatible, and the DRM driver (`atmel_hlcdc_dc.c`) does **not** have this compatible in its `atmel_hlcdc_of_match` table. The DRM driver probe uses `of_match_node(atmel_hlcdc_of_match, dev->dev->parent->of_node)` to find the layer descriptors — this lookup will fail, and the display controller will not work at runtime. The MFD driver side is fine (it already has the match), but the DRM side is broken.

Additionally, the series mixes an unrelated touchscreen config change into a display-focused series, has a minor DT style issue, and uses a non-standard patch ordering.
