No, I only keep them locally, but I would hope they are easy enough to
reproduce. If you can't figure out the problem right away, I can send
you the config files of course.

Just noticed another issue in my logs:

4. ARCH_DAVINCI no longer selects RESET_CONTROLLER
drivers/clk/davinci/psc.o: In function `__davinci_psc_register_clocks':
psc.c:(.text+0x3f8): undefined reference to `devm_reset_controller_register'
drivers/clk/davinci/psc-da850.o: In function `da850_psc0_init':
psc-da850.c:(.text+0x14): undefined reference to `reset_controller_add_lookup'
