dsp_clock_disable_all - Disable all active clocks Driver's device context structure

This function disables all the peripheral clocks that were enabled by DSP. It is meant to be called only when DSP is entering hibernation or when DSP is in error state.

dsp_clock_enable_all - Enable clocks used by the DSP Driver's device context strucure

This function enables all the peripheral clocks that were requested by DSP.

void dsp_gpt_wait_overflow	(	short int	clk_id,
		unsigned int	load
	)

dsp_gpt_wait_overflow - set gpt overflow and wait for fixed timeout : GP Timer clock id. : Overflow value.

Sets an overflow interrupt for the desired GPT waiting for a timeout of 5 msecs for the interrupt to occur.
