That question made me think though: this approach seems backwards. It
seems like someone did copy/paste/fork, and then we're asking the
authors of the original driver to un-fork? It seems like this should
happen the other way around -- those trying to support a new incarnation
should have looked to try to abstract the original driver for their
uses first.
IIUC, that's exactly what Rockchip did for much of their Analogix eDP
code -- they reworked the Exynos DP driver to split common Analogix code
from any Exynos-specific bits.
And actually, the current stuff in
drivers/gpu/drm/bridge/synopsys/dw-mipi-dsi.c is completely unused. It
exports some functions, but I see no users of it. Is that intended? Is
somebody already working on refactoring existing Rockchip code to use
this?
