Subject: [v1] dt-bindings: msm:disp: update dsi and dpu bindings
Date: Tue, 4 Feb 2020 19:45:37 +0530 [thread overview]
Message-ID: <1580825737-27189-1-git-send-email-harigovi@codeaurora.org> (raw)
Updating bindings of dsi and dpu by adding and removing certain
properties.
Signed-off-by: Harigovindan P <harigovi@codeaurora.org>
---
Changes in v1:
- Adding "ahb" clock as a required property.
- Adding "bus", "rot", "lut" as optional properties for sc7180 device.
- Removing properties from dsi bindings that are unused.
- Removing power-domain property since DSI is the child node of MDSS
and it will inherit supply from its parent.
