From 1c4c44f34fac73eae41e9ab8cef5f3fa754304f5 Mon Sep 17 00:00:00 2001 From: Matthias Reichl Date: Mon, 12 Oct 2020 19:35:04 +0200 Subject: [PATCH] linux (RPi4): disable legacy framebuffer and dmaengine drivers The legacy drivers are not used and this frees up one of the scarce DMA channels. Keep the legacy drivers enabled on RPi and RPi2 for now, they don't suffer from the DMA channel shortage and it may help downstream projects which still do RPi builds using the legacy graphics stack.
