Typical PC cards +* are the Orange Mobile 3G Option GlobeTrotter Fusion card. +* +* The U132 adapter will *NOT *work with PC cards that do not contain +* an OHCI controller. A simple way to test whether a PC card has an +* OHCI controller as an interface is to insert the PC card directly +* into a laptop(or desktop) with a CardBus slot and if "lspci" shows +* a new USB controller and "lsusb -v" shows a new OHCI Host Controller +* then there is a good chance that the U132 adapter will support the +* PC card.(you also need the specific client driver for the PC card) +* +* Please inform the Author and Maintainer about any PC cards that +* contain OHCI Host Controller and work when directly connected to +* an embedded CardBus slot but do not work when they are connected +* via an ELAN U132 adapter. +* +* The driver consists of two modules, the "ftdi-u132" module is +* a USB client driver that interfaces to the FTDI chip within +* the U132 adapter manufactured by Elan Digital Systems, and the +* "u132-hcd" module is a USB host controller driver that talks +* to the OHCI controller within CardBus card that are inserted +* in the U132 adapter. +* +* The "ftdi-u132" module should be loaded automatically by the +* hot plug system when the U132 adapter is plugged in. The module +* initialises the adapter which mostly consists of synchronising +* the FTDI chip, before continuously polling the adapter to detect +* PC card insertions. As soon as a PC card containing a recognised +* OHCI controller is seen the "ftdi-u132" module explicitly requests +* the kernel to load the "u132-hcd" module. +* +* The "ftdi-u132" module provides the interface to the inserted +* PC card and the "u132-hcd" module uses the API to send and receive +* data. The API features call-backs, so that part of the "u132-hcd" +* module code will run in the context of one of the kernel threads +* of the "ftdi-u132" module. +* +*/ +int ftdi_elan_switch_on_diagnostics(int number); +void ftdi_elan_gone_away(struct platform_device *pdev); +void start_usb_lock_device_tracing(void); +struct u132_platform_data { + u16 vendor; + u16 device; + u8 potpg; + void (*port_power) (struct device *dev, int is_on); + void (*reset) (struct device *dev); +}; +int usb_ftdi_elan_edset_single(struct platform_device *pdev, u8 ed_number, + void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, + void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, + int toggle_bits, int error_count, int condition_code, int repeat_number, + int halted, int skipped, int actual, int non_null)); +int usb_ftdi_elan_edset_output(struct platform_device *pdev, u8 ed_number, + void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, + void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, + int toggle_bits, int error_count, int condition_code, int repeat_number, + int halted, int skipped, int actual, int non_null)); +int usb_ftdi_elan_edset_empty(struct platform_device *pdev, u8 ed_number, + void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, + void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, + int toggle_bits, int error_count, int condition_code, int repeat_number, + int halted, int skipped, int actual, int non_null)); +int usb_ftdi_elan_edset_input(struct platform_device *pdev, u8 ed_number, + void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, + void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, + int toggle_bits, int error_count, int condition_code, int repeat_number, + int halted, int skipped, int actual, int non_null)); +int usb_ftdi_elan_edset_setup(struct platform_device *pdev, u8 ed_number, + void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, + void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, + int toggle_bits, int error_count, int condition_code, int repeat_number, + int halted, int skipped, int actual, int non_null)); +int usb_ftdi_elan_edset_flush(struct platform_device *pdev, u8 ed_number, + void *endp); +int usb_ftdi_elan_read_pcimem(struct platform_device *pdev, int mem_offset, + u8 width, u32 *data); +int usb_ftdi_elan_write_pcimem(struct platform_device *pdev, int mem_offset, + u8 width, u32 data); |
