VC4 DSI0 DSI1 MODULE(9)

💖 VC4 DSI0/DSI1 module 💖

okay bestie, welcome to the module(9) page from the Kernel API Manual — it’s giving kernel graphics realness and I’m obsessed. ✨

So like, BCM2835 lowkey contains two DSI modules: DSI0 and DSI1. DSI0 is a single-lane DSI controller, while DSI1 is a more modern 4-lane DSI controller. The way they’re built different fr fr. 💅

Most Raspberry Pi boards expose DSI1 as their "DISPLAY" connector, while the compute module brings both DSI0 and DSI1 out. iykyk 🎀

This driver has been tested for DSI1 video-mode display only currently, with most of the information necessary for DSI0 hopefully present. Not me hoping the DSI0 info is all there 🙈 — that’s literally what the page says.
