&hdptxphy_hdmi0? That looks like a downstream thing and also for the
wrong port?

You are right. I was refering to the patch of rock5b from mailing list[1],
in which there is "&hdptxphy_hdmi0" so I assumed this port is merged
upstream.

Although ROCK 5 ITX only uses hdmi1, vop need &hdptxphy0 for pll clk, so
this node is necessary if we don't change the vop clocks at board level
devicetree.

I just notice that there is a new patch series[2] to let phy of hdmi1
provide clk. I have to add both hdptxphy0 and hdptxphy1 based on this
series, or I can only add hdptxphy1 and change the vop clk like:

&vop {
	clocks = <&cru ACLK_VOP>,
		 <&cru HCLK_VOP>,
		 <&cru DCLK_VOP0>,
		 <&cru DCLK_VOP1>,
		 <&cru DCLK_VOP2>,
		 <&cru DCLK_VOP3>,
		 <&cru PCLK_VOP_ROOT>,
		 <&hdptxphy1>;
	clock-names = "aclk",
		      "hclk",
		      "dclk_vp0",
		      "dclk_vp1",
		      "dclk_vp2",
		      "dclk_vp3",
		      "pclk_vop",
		      "pll_hdmiphy1";
};

Jianfeng,

Is there anywhere repo with this patch applied to test it on rock5 itx hw?

(asking as I can’t get it working; even with hdmi1 only vop clocks like here: https://gist.github.com/warpme/49feadbe1f53ea31fca76f41d5bb3ee4)

This patch is applied to 6.13 and I was testing with armbian:
https://github.com/armbian/build/pull/7829.

>(asking as I can’t get it working; even with hdmi1 only vop clocks like here: https://gist.github.com/warpme/49feadbe1f53ea31fca76f41d5bb3ee4)

vop has a dependency of hdptxphy0, so only hdptxphy1 won't work.
If you are testing with 6.13 or 6.14, you have to add hdptxphy_hdmi0, and
if you are testing with linux-next, you should add hdptxphy0.

And I recommend testing with this series since it adds more display mode
support to hdmi1:
https://patchwork.kernel.org/project/linux-rockchip/list/?series=934232

Jianfeng

Well - i build 6.12.3 with current armbian patches:

https://github.com/armbian/build/tree/main/patch/kernel/archive/rockchip64-6.13 (all rk3588-*.patch)

 + https://github.com/armbian/build/pull/7829

and i’m still getting:

Initially i was thinking my board is defective but…..hdmi1 works nicely with Roobi OS flashed by radxa in eMMC so i’m really puzzled with this…

Is it possible to provide me url with kernel package you are using (wich works ok for you)?

It seems that hdmi qp driver is built in kernel, while armbian builds it
as module. I don't know if this is related. And here is the dmesg output
of drm on armbian:

I'm working on 6.14-rc2 now and this patch is included in this armbian pr:
https://github.com/armbian/build/pull/7835

And here is the kernel deb I built, which is confirmed working:

Many thx!
This is very kind!

I flashed, booted …. and have exactly the same symptoms & logs like on my previous email :-(

Being desperate I reflowed hdmi ports board area and - believe or not - this seems to help (albeit don’t know for how long :-)
Now hdmi1 works nicely.

Jianfeng, many thx for your persistence with my hw mess….
