int __must_check __pcmcia_request_exclusive_irq	(	struct pcmcia_device *	p_dev,
		irq_handler_t	handler
	)

pcmcia_request_exclusive_irq() - attempt to request an exclusive IRQ first : the associated PCMCIA device : IRQ handler to register

pcmcia_request_exclusive_irq() is a wrapper around request_irq() which attempts first to request an exclusive IRQ. If it fails, it also accepts a shared IRQ, but prints out a warning. PCMCIA drivers should allow for IRQ sharing and either use request_irq directly (then they need to call free_irq() themselves, too), or the pcmcia_request_irq() function.

void pcmcia_disable_device ( struct pcmcia_device * p_dev )

pcmcia_disable_device() - disable and clean up a PCMCIA device : the associated PCMCIA device

pcmcia_disable_device() is the driver-callable counterpart to pcmcia_enable_device(): If a PCMCIA device is no longer used, drivers are expected to clean up and disable the device by calling this function. Any I/O ranges (iomem and ioports) will be released, the Vpp voltage will be set to 0, and IRQs will no longer be generated – at least if there is no other card function (of multifunction devices) being used.

int pcmcia_enable_device ( struct pcmcia_device * p_dev )

pcmcia_enable_device() - set up and activate a PCMCIA device : the associated PCMCIA device

pcmcia_enable_device() physically enables a PCMCIA device. It parses the flags passed to in and stored in ->flags and sets up the Vpp voltage, enables the speaker line, I/O ports and store proper values to configuration registers.

int pcmcia_fixup_iowidth ( struct pcmcia_device * p_dev )

pcmcia_fixup_iowidth() - reduce io width to 8bit : pcmcia device

pcmcia_fixup_iowidth() allows a PCMCIA device driver to reduce the IO width to 8bit after having called pcmcia_enable_device() previously.

int pcmcia_fixup_vpp	(	struct pcmcia_device *	p_dev,
		unsigned char	new_vpp

pcmcia_fixup_vpp() - set Vpp to a new voltage level : pcmcia device : new Vpp voltage

pcmcia_fixup_vpp() allows a PCMCIA device driver to set Vpp to a new voltage level between calls to pcmcia_enable_device() and pcmcia_disable_device().

pcmcia_map_mem_page() - modify iomem window to point to a different offset : pcmcia device : iomem resource already enabled by pcmcia_request_window() : card_offset to map

pcmcia_map_mem_page() modifies what can be read and written by accessing an iomem range previously enabled by pcmcia_request_window(), by setting the card_offset value to .

pcmcia_read_config_byte() reads a byte from a configuration register in attribute memory.

int pcmcia_release_configuration ( struct pcmcia_device * p_dev )

pcmcia_release_configuration() - physically disable a PCMCIA device : pcmcia device

pcmcia_release_configuration() is the 1:1 counterpart to pcmcia_enable_device(): If a PCMCIA device is no longer used by any driver, the Vpp voltage is set to 0, IRQs will no longer be generated, and I/O ranges will be disabled. As pcmcia_release_io() and pcmcia_release_window() still need to be called, device drivers are expected to call pcmcia_disable_device() instead.

int pcmcia_release_window	(	struct pcmcia_device *	p_dev,

pcmcia_release_window() - release reserved iomem for PCMCIA devices : pcmcia device : iomem resource to release

pcmcia_release_window() releases &struct resource *res which was previously reserved by calling pcmcia_request_window().

int pcmcia_request_io ( struct pcmcia_device * p_dev )

pcmcia_request_io() - attempt to reserve port ranges for PCMCIA devices : the associated PCMCIA device

pcmcia_request_io() attempts to reserve the IO port ranges specified in &struct pcmcia_device ->resource[0] and ->resource[1]. The "start" value is the requested start of the IO port resource; "end" reflects the number of ports requested. The number of IO lines requested is specified in &struct pcmcia_device ->io_lines.

pcmcia_request_irq() - attempt to request a IRQ for a PCMCIA device : the associated PCMCIA device : IRQ handler to register

pcmcia_request_irq() is a wrapper around request_irq() which allows the PCMCIA core to clean up the registration in pcmcia_disable_device(). Drivers are free to use request_irq() directly, but then they need to call free_irq() themselfves, too. Also, only IRQF_SHARED capable IRQ handlers are allowed.

pcmcia_request_window() - attempt to reserve iomem for PCMCIA devices : the associated PCMCIA device : &struct resource pointing to p_dev->resource[2..5] : access speed

pcmcia_request_window() attepts to reserve an iomem ranges specified in &struct resource pointing to one of the entries in &struct pcmcia_device ->resource[2..5]. The "start" value is the requested start of the IO mem resource; "end" reflects the size requested.
