You should click through some of the links to see where the clashes actually happened. It didn't have anything to do with the actual hardware support. Rather, it was over stupid shit like the kernel DMA team throwing a hissy fit over the idea of there being Rust bindings for the DMA interface: https://lore.kernel.org/lkml/20250108122825.136021-3-abdiel....

When the response to such a small contribution is just "No rust code in kernel/dma, please" with a complete shutdown of any attempt to discuss alternatives, it's kinda pointless. Even though Rust is supposed to be an allowed language in the kernel now, with blessing from Linus himself, there's apparently just submaintainers of critical, highly shared infrasture that outright refuse it.

So this has nothing to do with "who will own the Apple drivers?!" but just the rest of the kernel going "your integration layers are an affront to our Holy C, begone religious heretics!"
