Subject: [RFC PATCH 0/2] Update reserved memory for simple framebuffer
Date: Wed, 19 Feb 2020 19:43:40 +0100 [thread overview]
Message-ID: <20200219184342.15974-1-michael@amarulasolutions.com> (raw)
Reserved memory for simple frame buffer should be created in a different
way:
+ aliases {
+ display0 = &lcdif;
+ };
+
+ reserved-memory {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ display_reserved: framebuffer at 86fa2000 {
+ reg = <0x86fa2000 0x80000>;
+ no-map;
+ };
+
+ };
We add a function to change the loaded dts and inject those information.
I have added another patch for meson. Right now I'm testing on tinker-s
board
