Subject: [PATCH v2 RESEND 0/3] Add LVDS display support and PLL handling
Date: Wed, 22 Oct 2025 14:43:48 +0530	[thread overview]

Hi all,

This patch series adds LVDS display support for the Atmel HLCDC driver
and introduces proper handling of the LVDS PLL clock required for such
panels.

The Atmel XLCDC IP supports multiple output types — Parallel RGB, MIPI
DSI, and LVDS. While the existing implementation handles RGB and MIPI
displays using the LCD generic clock (sys_clk), LVDS panels require the
dedicated LVDS PLL clock (lvds_pll_clk).Configuring the LVDS PLL clock
rate automatically based on the panel pixel clock, eliminates the need
for assigned-clock-rates entries in the device tree

Change logs are mentioned in individual patches
