void mcp_disable

(

struct mcp *

mcp

)

mcp_disable - disable the MCP interface : MCP interface to disable

Disable the MCP interface. The MCP interface will only be disabled once the number of calls to mcp_enable matches the number of calls to mcp_disable.

void mcp_enable

(

struct mcp *

)

mcp_enable - enable the MCP interface : MCP interface to enable

Enable the MCP interface. Each call to mcp_enable will need a corresponding call to mcp_disable to disable the interface.

unsigned int mcp_reg_read	(	struct mcp *	mcp,
		unsigned int	reg
	)

mcp_reg_read - read a device register : MCP interface structure : 4-bit register index

Read a device register and return its value. The MCP interface must be enabled to prevent this function hanging.

Definition at line 117 of file mcp-core.c.

void mcp_reg_write	(	struct mcp *	mcp,
		unsigned int	reg,
		unsigned int	val
	)

mcp_reg_write - write a device register : MCP interface structure : 4-bit register index : 16-bit data value

Write a device register. The MCP interface must be enabled to prevent this function hanging.

void mcp_set_audio_divisor	(	struct mcp *	mcp,
		unsigned int	div
	)

mcp_set_audio_divisor - set the audio divisor : MCP interface structure : SIB clock divisor

Set the audio divisor on the MCP interface.

Definition at line 80 of file mcp-core.c.

void mcp_set_telecom_divisor	(	struct mcp *	mcp,
		unsigned int	div
	)

mcp_set_telecom_divisor - set the telecom divisor : MCP interface structure : SIB clock divisor

Set the telecom divisor on the MCP interface. The resulting sample rate is SIBCLOCK/div.
