Subject: [PATCH v3 3/3] ARM: dts: stm32: fix several DT warnings on stm32mp15
Date:   Wed, 17 May 2023 16:35:42 +0200

Several warnings regarding LTDC and DSI on stm32mp15* device-trees remains.

Those concern:
  * "#size-cells" and "#address-cells" wrongly used
  * residual "reg" property appearing on endpoints where it could be
    avoided
  * Changed 'panel-dsi@0' to 'panel@0' according to dsi-controller.yaml
