In order to avoid any probe ordering issue, the best practice is to move the secondary MIPI-DSI device registration and attachment to the MIPI-DSI host at probe time. Let's do this.

This patch landed in linux-next as commit 864c49a31d6b ("drm/bridge: adv7511: Register and attach our DSI device at probe"). Sadly it causes endless probe-fail-defer loop on DragonBoard 410c board (arch/arm64/boot/dts/qcom/apq8016-sbc.dts):
I'm sorry to hear that (but would have been surprised if it didn't occur)
This is supposed to be fixed by 8f59ee9a570c ("drm/msm/dsi: Adjust probe order"). Do you have that patch applied?
