Subject: [PATCH 3/8] dt-bindings: display: rockchip,dw-mipi-dsi: Drop address/size cells
When the dw-mipi-dsi binding was initially added in commit
a20d86e7f964 ("Documentation: dt-bindings: Add bindings for rk3288 DW MIPI DSI driver")
the #address-cells and #size-cells were added as required properties.
When the binding was converted to yaml format in commit
0dac2102cf6b ("dt-bindings: display: rockchip: convert dw_mipi_dsi_rockchip.txt to yaml")
those properties were demoted to optional and removed from the binding
example.
As for the compatibles:
- rockchip,px30-mipi-dsi removed in this patch set
- rockchip,rk3128-mipi-dsi never used
- rockchip,rk3288-mipi-dsi added (invalid); later removed [1]
- rockchip,rk3399-mipi-dsi removed in this patch set
- rockchip,rk3568-mipi-dsi never used
- rockchip,rv1126-mipi-dsi proposed (invalid); never accepted [2]
[1] 282e2e078ba5 ("ARM: dts: rockchip: Remove #address/#size-cells from rk3288 mipi_dsi")
[2] https://lore.kernel.org/all/20230731110012.2913742-12-jagan@edgeble.ai/
The #address-cells and #size-cells are useful (and required) in the
ports node and for panel(s), but those properties are declared in their
schemas already. Now that there are no remaining users, remove these
properties from the Rockchip specific extensions of the Synopsys
DesignWare MIPI DSI host controller.
