Full remove warning : ret = of_get_drm_display_mode(panel->dev->of_node, mode, p->desc->bus_format, change to: ret = of_get_drm_display_mode(panel->dev->of_node, mode, (u32 *)&p->desc->bus_format, and delete unused variable line 379,470,525 I am not familiar upstream policy and it aim is not bit-to-bit compatible with the rockchip kernel. This patch driver make drive a dsi panel easy, so I shared this to armbian build system.I hope it help someone drive dsi panel easy.

I'm sorry about this driver has 4 warnings when I checked it,and the bus_format actually is bus_flags, I used the wrong name, although it not effect use, I will fix it when I have time in the future. This dirver is differ in upstream panel-simple-dsi, panel-simple-dsi actually contain a lot sets panel model.but this panel-dsi-simple is universal driver,you just put init code,config to dts and not need adjsut driver c code when drive a new panel model.

@Erica I have encountered something troublesome, and I am troubled by it. I'm afraid I don't have time to deal with this problem, so don't wait for me,I'm sorry.

@Erica now apt system media edge is 6.2.0,current is 6.1.11,maybe you can try: If you decide use 6.2: apt install linux-headers-edge-media If you decide use 6.1: apt install linux-headers-current-media armbian build system has some adjustments,so I am not sure it compatible your system and I am not know how find the deb.

@Erica It depends on linux-headers-xxx-xxx, like below: root@MusicPI:~# dpkg -l |grep linux-headers ii linux-headers-edge-media 23.02.2 arm64 Linux kernel headers for 6.2.0-media on arm64 edge

@atonejust worked,driver in here https://github.com/iamdrq/panel-edp-friendlyelec

@EricaCould you have a look right top's message box?I known how enable overlay on nanopct4 that used media kernel.that is a little trouble.

@atoneOk,I saw that.But nanopct4 used media kernel that it use extlinux havn't overlay. It need adjust some file in path /boot,I send mesage to Erica

@suhail dtc /sys/firmware/fdt > now.dts Please execute upper command then upload the now.dts file to there.

@EricaOk,let's look whether boot over extlinux ls -alh /boot

@EricaPlease show me uname -a

If you need help @ me please else I don't recive notify and my time zone is GMT+8. https://www.armbian.com/rockpro64/ at the bottom Rolling weekly releases has linux 6.1 image . Of course,I suggest you use a sdcard as test first if you use emmc now. I don't have a rockpro64, only have nanopct4 and orangepi4 as rk3399 board. But I guess it has same way that they also use rk3399. 1. I suppose you use linux kernel 6.x at rockpro64 and swtich user to root, create pine64-lcd.dts and put below content: /dts-v1/; /plugin/; / { compatible = "rockchip,rk3399"; fragment@0 { target=<&backlight>; __overlay__ { status = "okay"; }; }; fragment@1 { target=<&touch>; __overlay__ { status = "okay"; }; }; fragment@2 { target=<&mipi_dsi>; __overlay__ { status = "okay"; }; }; fragment@3 { target=<&vopl>; __overlay__ { status = "okay"; }; }; fragment@4 { target=<&vopl_mmu>; __overlay__ { status = "okay"; }; }; fragment@5 { target=<&vopb>; __overlay__ { status = "okay"; }; }; fragment@6 { target=<&vopb_mmu>; __overlay__ { status = "okay"; }; }; }; 2. exec below command, then reboot. armbian-add-overlay pine64-lcd.dts

Could you use edge kernel linux 6.1? Because it includes drivers that it doesn't need build kernel by yourself. And which model your lcd? It marks on the lcd back board.

So, it worked now ?

Actually, this easy. Because I found main line kernel support this display panel since linux 6.0,touch https://github.com/torvalds/linux/blob/4fe89d07dcc2804c8b562f6c7896a45643d34b2f/arch/arm64/boot/dts/rockchip/rk3399-rockpro64.dtsi#L582,lcd https://github.com/torvalds/linux/blob/4fe89d07dcc2804c8b562f6c7896a45643d34b2f/arch/arm64/boot/dts/rockchip/rk3399-rockpro64.dtsi#L629 If use linux 5.15, you need copy upper 2 section dts and enable touch,lcd as overlay. If use linux 6.0 and latter,you just enable touch,lcd as overlay.
