[PATCH v2 0/2] drm: bridge: ti-sn65dsi83: Improve dual-link LVDS support

[Sudarshan Shetty <tessolveupstream@gmail.com>]

Hi all,

This patch series improves dual-link LVDS support in the SN65DSI83
DSI-to-LVDS bridge driver.

Currently the driver programs identical horizontal timing parameters
for both single-link and dual-link LVDS modes. According to TI
documentation, when operating in dual-link mode the horizontal timing
values must be divided by two before being programmed into the device.
Without this adjustment, some panels fail to light up or produce
corrupted output.

TI also provides recommended register settings for dual-link LVDS
operation. This series adds support for an optional DT property
ti,dual-link-video-mode that enables the required configuration
in the driver.

When the property is present, the driver applies the recommended
register settings and uses a simplified DSI video mode configuration
to ensure correct dual-link LVDS operation.

Summary:
 - Add DT binding for ti,dual-link-video-mode
 - Add driver support to enable dual-link LVDS configuration
 - Apply recommended register settings for dual-link operation
 - Adjust DSI mode flags when dual-link mode is enabled

Changes in v2:
 - Introduce ti,dual-link-video-mode DT property
 - Add DT binding documentation for the new property
 - Update driver to read the DT property and apply dual-link
   configuration conditionally
 - Adjust DSI mode flags when dual-link video mode is enabled
 - Update commit messages

Thanks,
Anusha
