I'm confused. simple-framebuffer is a mechanism for which the entire point is that the kernel doesn't need the driver for. Why do you need to have patches for bridges and panels for simple-framebuffer?

So it's not about simple-framebuffer at all, but rather that you don't want to re-initialize the hardware that has already been setup? If so, this isn't how you should do it, but rather: https://lore.kernel.org/all/CAKMK7uHtqHy_oz4W7F+hmp9iqp7W5Ra8CxPvJ=9BwmvfU-O0gg@xxxxxxxxxxxxxx/ Maxime
