Changes in v1:
- Added display DT nodes for sc7180
Changes in v2:
- Renamed node names
- Corrected code alignments
- Removed extra new line
- Added DISP AHB clock for register access
under display_subsystem node for global settings
Changes in v3:
- Modified node names
- Modified hard coded values
- Removed mdss reg entry
Changes in v4:
- Reverting mdp node name
- Setting status to disabled in main SOC dtsi file
- Replacing _ to - for node names
- Adding clock dependency patch link
- Splitting idp dt file to a separate patch
Changes in v5:
- Renaming "gcc_bus" to "bus" as per bindings (Doug Anderson)
- Making status as disabled for mdss and mdss_mdp by default (Doug Anderson)
- Removing "disp_cc" register space (Doug Anderson)
- Renaming "dsi_controller" to "dsi" as per bindings (Doug Anderson)
- Providing "ref" clk for dsi_phy (Doug Anderson)
- Sorting mdss node before dispcc (Doug Anderson)
This patch has dependency on the below series
