drm/panel: Add simple panel mode for the ARM RTSM (fcec4163) · Commits · 戴 / test

Having failed any attempts at a more generic solution, I fall back to the very specific solution: define a simple panel for the ARM RTSM emulated platforms. I am doing this so we can convert all old users from the previous fbdev driver to the PL111 DRM driver. This works fine as far as I can test, provided the device tree for RTSM AEMv8 is augmented accordingly.
