While this is generally not an issue for the usb blocks to work, but the clock driver will "think" it runs at 24 MHz. That becomes an issue for RK312x since SCLK_USB480M can be a parent for other HW blocks (users of mux_pll_src_5plls_p) but they never will choose this clock as their parent, because it runs at OSC frequency. This sets usb480m_phy as SCLK_USB480M's parent, which now runs and outputs the expected frequency of 480 MHz and the other blocks can choose SCLK_USB480M as their parent if needed.

While this is generally not an issue for the usb blocks to work, but the clock driver will "think" it runs at 24 MHz. That becomes an issue for RK312x since SCLK_USB480M can be a parent for other HW blocks (users of mux_pll_src_5plls_p) but they never will choose this clock as their parent, because it runs at OSC frequency. This sets usb480m_phy as SCLK_USB480M's parent, which now runs and outputs the expected frequency of 480 MHz and the other blocks can choose SCLK_USB480M as their parent if needed.
