These clocks are required for usb operation. pll_p_out4 needs to be set to 24 MHz. The other clocks default to "off" in order to save some energy. Signed-off-by: Marc Dietrich <marvin24@gmx.de>
Acked-by: Stephen Warren <redacted> Given the rest of the thread, this is fine for now. We can address any deficiencies in the bus clock and clk_m parenting when it's addressed globally for all boards later.
