Comment 13 for bug 1880125

Re-examining the output of the debug code I added a few weeks ago, I noticed that I had put a kprintf into clk-raspberrypi.c/raspberrypi_clk_probe(), and it never was invoked.

Thus, I think you're right that adding:

CONFIG_CLK_RASPBERRYPI=y
CONFIG_ARM_RASPBERRYPI_CPUFREQ=y

has a good chance of getting us past this problem.

I will try adding those lines to .../focal/debian.raspi/config/config.common.ubuntu. I'm having trouble building/running a modified kernel at the moment, but will do this as soon as I can.
