The bridge->of_node field is defined inside of an #ifdef, which results in a build failure when compile-testing the vc4_dsi driver without CONFIG_OF: drivers/gpu/drm/vc4/vc4_dsi.c: In function 'vc4_dsi_dev_probe': drivers/gpu/drm/vc4/vc4_dsi.c:1822:20: error: 'struct drm_bridge' has no member named 'of_node' 1822 | dsi->bridge.of_node = dev->of_node; Add another #ifdef in the place it is used in. Alternatively we could consider dropping the #ifdef in the struct definition and all other users. Fixes: 78df6403 ("drm/vc4: dsi: Convert to using a bridge instead of encoder") Signed-off-by:

This panel communicates brightness in big endian. This is not a quirk of the panels themselves, but rather, a part of the MIPI standard. Use the new mipi_dsi_dcs_set_display_brightness_large() function that properly handles 16-bit brightness instead of bypassing the brightness functions entirely. Signed-off-by:

The MIPI DCS specification demands that brightness values are sent in big endian byte order. It also states that one parameter (i.e. one byte) shall be sent/received for 8 bit wide values, and two parameters shall be used for values that are between 9 and 16 bits wide. Add new functions to properly handle 16-bit brightness in big endian, since the two 8- and 16-bit cases are distinct from each other.

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. Reviewed-by:

The bindings require that there is a next bridge after the lt9611. If nothing else it can be the hdmi-connector (as used on the RB3 platform, see sdm845-db845c.dts). Bring in the next bridge into the drm bridges chain and attach to it. Since lt9611 is not anymore the last bridge in the chain, this also allows us to drop all the !DRM_BRIDGE_ATTACH_NO_CONNECTOR functionality. Reviewed-by:

The mode_set callback is deprectated for drm_bridges in favour of using atomic_enable callback. Move corresponding code into the function lt9611_bridge_atomic_enable() and turn lt9611_bridge_pre_enable() into the proper atomic_pre_enable callback. Reviewed-by:

The driver will reset the bridge in the atomic_pre_enable(). However this will also drop the HPD interrupt state. Instead of resetting the bridge, properly wake it up.

On atomic_post_disable the bridge goes to the low power state. However the code disables too much of the chip, so the HPD event is not being detected and delivered to the host.
