Using soquartz's MIPI DSI1 output
#1
I am currently trying (with no success so far) to start the DSI1 output with a 4-lane DSI panel on the soquartz module, using a RPi CM4 IO board as baseboard. I use a custom panel based on a Fitipower JD9365DA chip (I already have a kernel driver for it, tested on a RPi CM4 on the same baseboard). Note that it is my first project with a module based on a rockchip SoC.

As I understand from the kernel dts bindings documentation and headers, rockchip mipi dsi drivers, and existing quartz-a (which has a dsi0 output) and soquartz dts files, my dts must create the following pipeline by linking peripherals ports (and also enable the video_phy1 node used as dphy by the DSI1 node) :

VOP out (choosed vp0) >> DSI1 in >> DSI1 out >> Panel in

My work is based on a fork of @pgwipeout kernel tree retrieved from https://gitlab.com/pgwipeout/linux-next main branch. I use the u-boot build from https://gitlab.com/pgwipeout/quartz64_ci pipeline artifacts. My rootfs is a custom one based on Alpine's AArch64 rootfs.

Here is my DTS file (only shows the diff from the original rk3566-soquartz-cm4.dts)

Code:
&dsi1 {
        status = "okay";
        clock-master;

        ports {
                dsi1_out: port@1 {
                        reg = <1>;
                        #address-cells = <1>;
                        #size-cells = <0>;

                        dsi1_out_panel: endpoint {
                                remote-endpoint = <&panel_in_dsi>;
                        };
                };
        };

        mipi_panel: panel@0 {
                compatible = "fitipower,jd9365da";
                reg=<0>;

                backlight = <&panel_backlight>;
                reset-gpios = <&gpio3 RK_PD1 GPIO_ACTIVE_HIGH>;

                port {
                        panel_in_dsi: endpoint {
                                remote-endpoint = <&dsi1_out_panel>;
                        };
                };
        };
};

&dsi1_in {
        dsi1_in_vp0: endpoint@0 {
                reg = <0>;
                remote-endpoint = <&vp0_out_dsi1>;
        };
};

&video_phy1 {
        status = "okay";
};

&vp0 {
        vp0_out_dsi1: endpoint@RK3568_VOP2_EP_MIPI1 {
                reg = <RK3568_VOP2_EP_MIPI1>;
                remote-endpoint = <&dsi1_in_vp0>;
        };
};

&vop {
        assigned-clocks = <&cru DCLK_VOP0>;
        assigned-clock-parents = <&pmucru PLL_HPLL>, <&cru PLL_VPLL>;
        status = "okay";
};

&vop_mmu {
        status = "okay";
};

Everything builds OK, the boards boots properly, and the nodes show up in /sys (got both vop, dsi and my driver, see below), but it seems like nothing is really started. I added some pr_warn() calls in the beginning of my panel driver dsi_probe() function, they never show up in dmesg, and Xorg fails to start with a "no screen detected" message. U-boot seems to detect the video output pipeline after loading the dtb (it tries to load a boot logo since I modified the dts).

I have no errors regarding the VOP / DSI / panel in my dmesg / boot logs (see below), and only a warning regarding VOP2 IOMMU allocation which fails and fallbacks to a generic DMA (message : "Failed to allocate default IOMMU domain of type 4 for group (null) - Falling back to IOMMU_DOMAIN_DMA"), maybe this is related to the problem ?

I also looked for power domains and clocks configuration in case some peripheral stays in standby / is not clocked, but failed to find what could cause my problem (as I just start working on RK356x SoCs, I may have missed something).

From what I saw on patchwork it seems like there is ongoing work on the VOP2 / DSI code in mainline, maybe I can try to rebase on mainline ?
If that's a driver issue, I am willing to give some time to provide a patch and testing to get it to work (but may need some insights from more experienced people on this SoC).

I will continue my tests / debugging and post my findings, but if anybody with more experience on this board has insights / clues / ideas (or even better, a solution  Smile ), that really can help me.

Indeed. pgwipeout's tree uses an early vop2 patchset, the one in mainline has had many revisions since then. Reportedly MIPI-DSI was working at some point but stopped working in the later revisions on the patchset I believe. A lot of things are in flux and it's half-merged at the moment, so a bit messy to play with.

Your best bet is probably kernel 5.18 with the iommu patchset (referenced in the vop2 cover letter) and the vop2 v11 patchset on top, and then try to get DSI working there. 5.19 will be messier due to the device tree stuff not being merged.
