void st_kim_ref	(	struct st_data_s **	core_data,
		int	id
	)

st_kim_ref - reference the core's data This references the per-ST platform device in the arch/xx/ board-xx.c file. This would enable multiple such platform devices to exist on a given platform

long st_kim_start

(

void *

kim_data

)

st_kim_start - called from ST Core upon 1st registration This involves toggling the chip enable gpio, reading the firmware version from chip, forming the fw file name based on the chip version, requesting the fw, parsing it and perform download(send/recv).

Definition at line 456 of file st_kim.c.

long st_kim_stop

(

void *

kim_data

)

st_kim_stop - stop communication with chip. This can be called from ST Core/KIM, on the- (a) last un-register when chip need not be powered there-after, (b) upon failure to either install ldisc or download firmware. The function is responsible to (a) notify UIM about un-installation, (b) flush UART if the ldisc was installed. (c) invoke platform's chip disabling routine.
