config VIDEO_BRIDGE bool "Support video bridges" depends on DM help Some platforms use video bridges to convert from one output to another. For example, where the SoC only supports eDP and the LCD requires LVDS, an eDP->LVDS bridge chip can be used to provide the necessary conversion. This option enables support for these devices. config VIDEO_BRIDGE_PARADE_PS862X bool "Support Parade PS862X DP->LVDS bridge" depends on VIDEO_BRIDGE help The Parade PS8622 and PS8625 are DisplayPort-to-LVDS (Low voltage differential signalling) converters. They enable an LVDS LCD panel to be connected to an eDP output device such as an SoC that lacks LVDS capability, or where LVDS requires too many signals to route on the PCB. Setup parameters are provided in the device tree. config VIDEO_BRIDGE_NXP_PTN3460 bool "Support NXP PTN3460 DP->LVDS bridge" depends on VIDEO_BRIDGE help The NXP PTN3460 is a DisplayPort-to-LVDS (Low voltage differential signalling) converter. It enables an LVDS LCD panel to be connected to an eDP output device such as an SoC that lacks LVDS capability, or where LVDS requires too many signals to route on the PCB.
