[PATCH 0/2] rockchip: Fix devices suspend freeze on RK3568/RK3566

[Jonas Karlman]

This series fixes a system freeze during suspend in ohci_suspend() due
to clk_usbphy1_480m not being enabled when EHCI/OHCI registers are
accessed on e.g. a Raxa ROCK 3C board.

Following pm_test modes work on my ROCK 3C with the missing usbphy clk
refs added:

  echo N > /sys/module/printk/parameters/console_suspend

  echo devices > /sys/power/pm_test
  echo platform > /sys/power/pm_test
  echo processors > /sys/power/pm_test
  echo core > /sys/power/pm_test

  echo mem > /sys/power/state
