The existing implementation of the Samsung MIPI DSIM Bridge in
drivers/gpu/drm/bridge/sec-dsim.conly allows connecting DSI panels directly to the port. However, some panels have a bridge on the board itself, which needs to be configured and set up from the kernel. This patch not only adds the ability to connect a panel via a bridge but also fixes an issue where(struct drm_panel)->panelwas assignedERR_PTRinstead ofNULL, leading to a Kernel Panic when attempting to access a nonexistent address indrivers/gpu/drm/drm_panel.cwithin thedrm_panel_get_modes()function.This fix has been tested on the Raspberry Pi 7" touchscreen panel (800x480).
