Subject: [PATCH 0/2] rockchip: Fix devices suspend freeze on RK3568/RK3566
Date: Tue, 9 Jun 2026 15:41:21 +0000 [thread overview]
Message-ID: <20260609154124.445182-1-jonas@kwiboo.se> (raw)
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 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
