[PATCH] clk: rockchip: clk-rk3568.c: Add missing USB480M_PHY mux

Thu Apr 4 00:27:01 PDT 2024


From: David Jander <david at protonic.nl>

The USB480M clock can source from a MUX that selects the clock to come
from either of the USB-phy internal 480MHz PLLs. These clocks are
provided by the USB phy driver.
