<content type='text'>
Returns EPROBE_DEFER when of_drm_find_bridge() fails, this is consistent
with what all the other DRM bridge drivers are doing and this is
required since the bridge might not be there when the driver is probed
and this should not be a fatal failure.

Enable the drm bridge pre_enable_prev_first flag so that the
previous bridge pre_enable should be called first before the
pre_enable for the tc358764 bridge is called.

This makes sure that the previous bridge should be initialized
properly before the tc358764 bridge is powered up.

Same to i.MX8mp LDB, i.MX93 LDB is controlled by mediamix blk-ctrl
through LDB_CTRL and LVDS_CTRL registers.  i.MX93 LDB supports only
one LVDS channel(channel 0) and it's LVDS_CTRL register bit1 is used
as LVDS_EN instead of CH1_EN.  Add i.MX93 LDB support in the existing
i.MX8mp LDB bridge driver by adding i.MX93 LDB compatible string and
device data(to reflect different register offsets and LVDS_CTRL register
bit1 definition).

If the bridge is connected using both DSI ports, the driver should use
both of them all the time. Correct programming sequence to always use
dual-port mode if both dsi0 and dsi1 are connected.
