Subjectsiimple-framebuffer rockchip persistent logo
Hi Kever

Trying to have a persistent banner from uboot to linux-kernel. I'm
right now working on linux-rockchip kernel but I think that the
problem is even on mainline

+ framebuffer: framebuffer@7f800000 {
+ compatible = "rockchip,simple-framebuffer",
+ "simple-framebuffer";
+ reg = <0x7f800000 (1920 * 1080 * 4)>;
+ width = <1920>;
+ height = <1080>;
+ stride = <(1920 * 4)>;
+ format = "a8b8g8r8";
+ clocks = <&cru PCLK_HDMI_CTRL>, <&cru SCLK_HDMI_HDCP>,
+ <&cru SRST_LCDC0_AXI>, <&cru
SRST_LCDC0_AHB>, <&cru SRST_LCDC0_DCLK>,
+ <&cru ACLK_VOP0>, <&cru HCLK_VOP0>;
+ status = "okay";
+ };

Seems that it get off before I reach the drm registration

[ 2.077495] simple-framebuffer 7f800000.framebuffer: framebuffer at
0x7f800000, 0x7e9000 bytes, mapped to 0xf0900000
[ 2.077519] simple-framebuffer 7f800000.framebuffer:
format=a8b8g8r8, mode=1920x1080x32, linelength=7680
[ 2.161225] simple-framebuffer 7f800000.framebuffer: fb0: simplefb
registered!
[ 3.433847] fb: switching to rockchip-drm-fb from simple

I don't find all the clocks and if those are the only think that I
need to stay on. Any suggestion?

Michael
