Hi Bruce,
Would you please help remove the obsolete branch standard/xlnx-soc in
linux-yocto-dev
and apply these patches for v5.10 as below to the new branch
standard/xlnx-soc?
There are 1451 patches in this pull request.
Among them, 1443 patches are picked from
https://github.com/Xilinx/linux-xlnx.git xlnx_rebase_v5.4 (tag
xlnx_rebase_v5.4_2020.2).
and some of them are modified to adapt to the v5.10. And there are 4
new patches.
I took at look at your branch and there are some interesting things.
First of all thanks for your work.
Do you use any script of it because I see you keep references to origin
sha1 which is quite nice?
Then obviously we need to switch to psgtr mainline driver and add
missing features because that's the only way to go in long run. I tested
Did you test sata by using v5.10 kernel? Do I need modify dts file
to enable psgtr for sata?
Yes. Here is for example setting for zcu102. I need to take a look at
others boards too.

Thank you very much. This helps me a lot.
you can normally used fixed-clock node for that. But one thing what I am
not sure with mainline psgtr driver is when you cat clk_summary you
can't really see ref count because none is calling clk_enable. That's
why I think when you have gt clock source provided from external device
you really should enable that clock before use it.
Thanks for the reminding. It gave me a great inspiration. I cat
clk_summary and
found that "dp_video_ref" is not enabled. This is an issue in dp driver
of mainline.
The clk "disp->pclk" in dp driver should be enabled then disabled in the
probe function, then
enable it again in zynqmp_disp_crtc_atomic_enable (This is what SDK DP
driver does) .
Mainline dp driver only enables it in zynqmp_disp_crtc_atomic_enable, so
the dp
subsystem don't send signal to the DP monitor.
And now the DP monitor can receive signals from the board but the screen
is black.
I will do more debug on it.
Thanks,
Quanyang
Some boards have si5341 chips that's why can be directly use. Some of
them should be done via fixed clocks.
And I didn't try anything else yet.
Thanks,
Michal
