Hi,
We have custom tda4 board and we plan to connect PPS signal from GPS device to GPIO0_125.
We enabled PPS support in kernel and added following changes in k3-j721e-common-proc-board.dts file:
Because the pins of uart1 are used in PPS of our board,so we have to disabled the uart1 in dts file:
After the changes are completed and compiled,we start the kernel.Log is here:

We can find that it failed to request for GPIO.
When I added Pinmux_Ctrl and GPIO_Ctrl related probe printing, I found that the PPS request GPIO before GPIO_Ctrl is probed.
I don't know if this probe order is the cause of this problem.

In addition, I can't use PPS to request other GPIO pin successfully.
So How can I use PPS to request for GPIO correctly?Is there a solution to adjust the order or time during the kernel loading.
