output enable sequence requiere the DSP clock. Some input from Wolfson will be needed to find out if this is just an undocumented requirement or a chip bug.

It seems it's an undocumented requirement.

• { "Left Output Mixer", "Left Bypass Switch", "CLK_DSP" },
• { "Left Output Mixer", "Right Bypass Switch", "CLK_DSP" },
• { "Right Output Mixer", "Left Bypass Switch", "CLK_DSP" },
• { "Right Output Mixer", "Right Bypass Switch", "CLK_DSP" },

The actual change here should be to add a route:

{ "Charge Pump", NULL, "CLK_DSP" },

Can you submit an update for this or should I do one?
