Hi,

At our custom board there are 2 hdmi outputs sor0 and sor2.
Those 2 outputs are connected to different vdd_hdmi_5v0-supply which calls:
p2822_vdd_hdmi2_5v0 which is define at head 2
p2822_vdd_hdmi_5v0 which is define at head 0
while the whole config file is :

#include <dt-bindings/display/tegra-dc.h>

};

&dpaux1 {
	status = "disabled";
};

&dpaux2 {
	status = "okay";
};

&tegra_cec {
	status = "okay";
};

During board startup head0::vdd_hdmi_5v0-supply overrides head1::vdd_hdmi_5v0-supply
If I disable head0 and sor2 head 1 is not overrides.

What cause to that issue and how can I solve it?

I don’t quite understand your comment here.

p2822_vdd_hdmi2_5v0 which is define at head 2

Why should it set in head2? Isn’t head2 being disabled? Is it a typo here?

Also, what is your method to know “head0::vdd_hdmi_5v0-supply overrides head1::vdd_hdmi_5v0-supply”?

4

Sorry it was a typo p2822_vdd_hdmi2_5v0 which is define at head 1

5

What is your method to tell that it is getting overridre?

6

We figure it out by elimination
1.disable head 0 and enable only head 1
2.swiytching between two heads.

From that we figure out that head 0 ovverides head 1 and disable p2822_vdd_hdmi2_5v0 as we can see from dmesg:

[   36.188991] vdd-1v8-cvb: disabling
[   36.189010] vdd-1v8-pwm-en: disabling
[   36.189018] vdd-epb-1v0: disabling
[   36.189025] avdd-cam-2v8: disabling
[   36.189031] vdd-sata-1v5: disabling
[   36.189037] vdd-1v8-slt: disabling

[   36.189054] vdd-hdmi2-5v0: disabling
[   36.189060] vdd_sys_en: disabling
7

Please use /proc/device-tree node on your device to see what is the device tree setting.

Your method to check “vdd-hdmi2-5v0: disabling” is not a meaningful method… it just tells us that this regulator is not in use. It has lots of possibilities to see such log… it does not represent “head0 overwrites head1”.

8

Hi

Can you give me an hint what to looking for at device tree?

9

/proc/device-tree is just the dts file loaded on the board.

Check if head0 and head1 really set the correct regulator as your expectation.

10

After using grep to looking for the power supply it looks like that only vdd_hdmi_5v0-supply exists
root@nvidia-desktop:/proc/device-tree/host1x# grep -r head1
Binary file nvdisplay@15210000/reset-names matches
root@nvidia-desktop:/proc/device-tree/host1x# grep -r head0
Binary file nvdisplay@15200000/reset-names matches

11

I am not sure how you can come up with that conclusion with the result you pasted…

You should go to each nvdisplay and use command “xxd” to dump the content of vdd_hdmi_5v0-supply.

12

Sorry for the misunderstanding I new with those issues

xxd gives me following info :

root@nvidia-desktop:/proc/device-tree/host1x/nvdisplay@15200000# xxd vdd_hdmi_5v0-supply
00000000: 0000 0075 …u

root@nvidia-desktop:/proc/device-tree/host1x/nvdisplay@15210000# xxd vdd_hdmi_5v0-supply
00000000: 0000 0077

root@nvidia-desktop:/proc/device-tree/host1x/nvdisplay@15220000# xxd vdd_hdmi_5v0-supply
00000000: 0000 0077 …w

What does it means??

13

You can check the phandle under p2822_vdd_hdmi_5v0 and p2822_vdd_hdmi2_5v0. It will tell the id of these regulators.

If it is no error, I guess one is 0x75 while another one is 0x77.

You can check that first. If this is as expectation, then the issue is something else, you should share the full dmesg as attachment.

I see no monitor is connected on both of your display head. Can you connect it and see if vdd-hdmi2-5v0 will not get disabled?

16

The dmesg when screen has been concected is :

and when check phandle at xxd I got the same hex values.
From that it seems that you corcect and the head using the correct regulator.

dmseg4Debug.txt (123.6 KB)

Now I more confused why when head0 is active the regulator of head1 is disable?

17

Hi,

Can you just tell me what did you do in your test?

Actually, from that log, I still see no log triggered from display driver.

Also, I still have no idea about what is your exact problem. If you are just wondering why you see “vdd-hdmi2-5v0: disabling” log. Then I need to say this question is a little pointless.

But if you are trying to ask the monitor is not able to get detected, then it is worth debugging.

18

Hi

The problem is that we are 2 HDMI connections on our board. each HDMI has it’s own regulator.
Our purpose is to make both display connections operational.
The problem is that the 5V pin at HDMI connector which controlled by p2822_vdd_hdmi2_5v0 is not active this is cause to that the connector is always inactive and if we connect a monitor there is not going to be monitor detection.
During our debugging process we tried to figure out why this HDMI is not working and we figure out that the 5V pin is 0.
Because of that we began to debug the regulator and its related HW and we found that the tegra does not enable the regulator even though the display is active which cause to detection malfunction.
In order to verify that this is the problem we forced the regulator to always active what cause to the HDMI to be functional.
After verfiy that the inactive regulator cause the issue we decided to disable head0 and to debug only head 1.
After that the regulator was active which cause to the display to be active.
After that we reactive head0 and again the display which was related to head1 was not functional beacuse the regulator output was which cause to the HDMI 5v pin to be 0 which indicates to inactive HDMI.

In order to verify that the regulator is ok we crossed between the 2 regulators while the 2 displayes were active and then we got that opposite results.
This indicated us that the regulator ok but there is some issue with the display configuration which cause to head0 regulator to be active head1 regulators not active which cause to issue with SOR2 display

19

Can you directly convert your dtb back to dts and attach it here?

20

Just want to confirm the status of your issue.

  1. disable head0, enable head 1 → head1 is working fine

  2. Enable both heads → only head0 can work.

Also, is this a typo again? SOR1 is not in use if I understand your case correctly.

head1 regulator is not active which cause to issue with SOR1 display

21

Ye you are correct
I am using Sor0 and sor2 while sor1 is disable
