The edp-24m clock has two possible sources: the 24MHz oscillator as well as an external 27MHz input. The power-on-default is the 27MHz clock which is not supplied on all Rockchip boards. While on all current boards and also all Veyron Chromebooks the bootloader seems to adapt the muxing to the internal source, this doesn't seem to be the case on headless veyron devices like brain and mickey making the edp-24m clock an orphan. On the hardware side the 27m input also is not connected at all. With the upcoming deferral of orphan-clocks this results in the power- domain code deferring, as it cannot request the needed clock and if the synchronous reset is sucessfullat all in this case is also unknown. So fix that by making sure, the edp-24m clock is muxed to the internal 24MHz oscillator at all times. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
