int umc_controller_reset

(

struct umc_dev *

umc

)

umc_controller_reset - reset the whole UMC controller : the UMC device for the radio controller.

Drivers or all capabilities of the controller will have their pre_reset methods called or be unbound from their device. Then all post_reset methods will be called or the drivers will be rebound.

Radio controllers must provide pre_reset and post_reset methods and reset the hardware in their start method.

If this is called while a probe() or remove() is in progress it will return -EAGAIN and not perform the reset.

struct umc_dev* umc_device_create ( struct device *  parent, int  n  )

read

umc_device_create - allocate a child UMC device : parent of the new UMC device.
: index of the new device.

The new UMC device will have a bus ID of the parent with '-n' appended.

int __must_check umc_device_register

(

struct umc_dev *

umc

)

umc_device_register - register a UMC device : pointer to the UMC device

The memory resource for the UMC device is acquired and the device registered with the system.

void umc_device_unregister

(

struct umc_dev *

umc

)

umc_device_unregister - unregister a UMC device : pointer to the UMC device

First we unregister the device, make sure the driver can do it's resource release thing and then we try to release any left over resources. We take a ref to the device, to make sure it doesn't disappear under our feet.

int umc_match_pci_id	(	struct umc_driver *	umc_drv,
		struct umc_dev *	umc

umc_match_pci_id - match a UMC driver to a UMC device's parent PCI device. : umc driver with match_data pointing to a zero-terminated table of pci_device_id's. : umc device whose parent is to be matched.
