Thank you very much. After a little bit of fiddling I can confirm that this also works fine on a Toradex
Colibri iMX8X [1] with either a Capacitive Touch Display 10.1" LVDS which has a Logic Technologies LT170410-
2WHC [2] single-channel panel inside or a dual-channel LG LP156WF1 full HD panel.
During boot I noticed quite some clocking/power domain related messages:
[ 0.537965] gpt0_clk: failed to attached the power domain -2
[ 0.562372] dc1_disp0_clk: failed to attached the power domain -2

[ 0.580368] mipi_csi0_pwm0_clk: failed to attached the power domain -2
And the following repeats a couple dozens of times:
[ 4.391495] dc1_disp0_clk: failed to get clock parent -22
[ 4.398532] dc1_disp1_clk: failed to get clock parent -22
And finally it spits the following:
[ 4.670303] imx8qxp-lpcg-clk 59580000.clock-controller: deferred probe timeout, ignoring dependency
[ 4.679629] imx8qxp-lpcg-clk: probe of 59580000.clock-controller failed with error -110
Despite those messages the displays do work fine once booted.
I am currently running this with SCFW, SECO, TF-A and U-Boot based off NXP's latest downstream BSP 5.4.70-
2.3.0. Not sure whether or not especially the used SCFW version could cause some issues. What SCFW are you
using?
Full boot logs may be found here [3].
You may add the following to the whole series.

Thanks again and just let us know if we may test anything else for you.
