Subject: [PATCH] dtoverlays: Rework vc4-kms-dpi overlays to remove
|
|
duplication
|
|
|
|
Removes all the common panel, dpi, and backlight configuration
|
|
from the individual vc4-kms-dpi-* files into vc4-kms-dpi.dtsi.
|
|
|
|
Creates a new vc4-kms-dpi-panel-overlay.dts for preconfigured
|
|
panels, with overrides to enable the different panel configurations.
|
|
|
|
Deprecates vc4-kms-dpi-at056tn53v1 as superceded by vc4-kms-dpi-panel.
|
|
vc4-kms-kippah-7inch not deprecated for now as it is likely to be
|
|
in wider use than at056tn53v1.
