vsf_sdio_init()

vsf_err_t vsf_sdio_init	(	vsf_sdio_t *	sdio_ptr,
		vsf_sdio_cfg_t *	cfg_ptr
	)

initialize a sdio instance.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	cfg_ptr	a pointer to structure vsf_sdio_cfg_t

Returns

vsf_err_t: VSF_ERR_NONE if sdio was initialized, or a negative error code

Note

It is not necessary to call vsf_sdio_fini() to deinitialization. vsf_sdio_init() should be called before any other sdio API except vsf_sdio_capability().

vsf_sdio_fini()

void vsf_sdio_fini

(

vsf_sdio_t *

sdio_ptr

)

finalize a sdio instance.

Parameters

[in]

sdio_ptr

a pointer to structure vsf_sdio_t

Returns

none

vsf_sdio_irq_enable()

void vsf_sdio_irq_enable	(	vsf_sdio_t *	sdio_ptr,
		vsf_sdio_irq_mask_t	irq_mask
	)

enable interrupt masks of sdio instance.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	irq_mask	one or more value of enum vsf_sdio_irq_mask_t

Returns

none.

Note

All pending interrupts should be cleared before interrupts are enabled.

vsf_sdio_irq_disable()

void vsf_sdio_irq_disable	(	vsf_sdio_t *	sdio_ptr,
		vsf_sdio_irq_mask_t	irq_mask
	)

disable interrupt masks of sdio instance.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	irq_mask	one or more value of enum vsf_sdio_irq_mask_t, vsf_sdio_irq_mask_t

Returns

none.

vsf_sdio_status()

vsf_sdio_status_t vsf_sdio_status

(

vsf_sdio_t *

sdio_ptr

)

get the status of sdio instance.

Parameters

[in]

sdio_ptr

a pointer to structure vsf_sdio_t

Returns

vsf_sdio_status_t: return all status of current sdio

vsf_sdio_capability()

vsf_sdio_capability_t vsf_sdio_capability

(

vsf_sdio_t *

sdio_ptr

)

get the capability of sdio instance.

Parameters

[in]

sdio_ptr

a pointer to structure vsf_sdio_t

Returns

vsf_sdio_capability_t: return all capability of current sdio vsf_sdio_capability_t

vsf_sdio_set_clock()

vsf_err_t vsf_sdio_set_clock	(	vsf_sdio_t *	sdio_ptr,
		uint32_t	clock_hz,
		bool	is_ddr
	)

set the clock of sdio instance.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	clock_hz	clock in Hz
[in]	is_ddr	is DDR mode, true means DDR mode while false means SDR mode

Returns

vsf_err_t: VSF_ERR_NONE if sdio set clock was successfully, or a negative error code

vsf_sdio_set_bus_width()

vsf_err_t vsf_sdio_set_bus_width	(	vsf_sdio_t *	sdio_ptr,
		uint8_t	bus_width
	)

set the bus width of sdio instance.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	bus_width	bus width in 1, 4, 8

Returns

vsf_err_t: VSF_ERR_NONE if sdio was successfully, or a negative error code

vsf_sdio_host_request()

vsf_err_t vsf_sdio_host_request	(	vsf_sdio_t *	sdio_ptr,
		vsf_sdio_req_t *	req
	)

request sdio operation in host mode.

Parameters

[in]	sdio_ptr	a pointer to structure vsf_sdio_t
[in]	req	a pointer to sdio rqeust structure

Returns

vsf_err_t: VSF_ERR_NONE if sdio was successfully, or a negative error code
