For dual os, logo memory will be reserved as following list, we can
get the currect memory from memory-region phandle:
/* DRM logo for OS0 */
drm_logo_os0: drm-logo-os0@90600000 {
reg = <0x00000000 0x90600000 0x00000000 0x02100000>;
compatible = "rockchip,drm-logo-os0";
};
/* DRM logo for OS1 */
drm_logo_os1: drm-logo-os1@92700000 {
reg = <0x00000000 0x92700000 0x00000000 0x02100000>;
compatible = "rockchip,drm-logo-os1";
};
OS0:
&display_subsystem {
memory-region = <&drm_logo_os0>, <&drm_cubic_lut>;
memory-region-names = "drm-logo", "drm-cubic-lut";
};
OS1:
&display_subsystem {
memory-region = <&drm_logo_os1>, <&drm_cubic_lut>;
memory-region-names = "drm-logo", "drm-cubic-lut";
};
