1/* 2* Common Header File for the Elan Digital Systems U132 adapter 3* this file should be included by both the "ftdi-u132" and 4* the "u132-hcd" modules. 5* 6* Copyright(C) 2006 Elan Digital Systems Limited 7*(http://www.elandigitalsystems.com) 8* 9* Author and Maintainer - Tony Olech - Elan Digital Systems 10*(tony.olech@elandigitalsystems.com) 11* 12* This program is free software;you can redistribute it and/or 13* modify it under the terms of the GNU General Public License as 14* published by the Free Software Foundation, version 2. 15* 16* 17* The driver was written by Tony Olech(tony.olech@elandigitalsystems.com) 18* based on various USB client drivers in the 2.6.15 linux kernel 19* with constant reference to the 3rd Edition of Linux Device Drivers 20* published by O'Reilly 21* 22* The U132 adapter is a USB to CardBus adapter specifically designed 23* for PC cards that contain an OHCI host controller. Typical PC cards 24* are the Orange Mobile 3G Option GlobeTrotter Fusion card. 25* 26* The U132 adapter will *NOT *work with PC cards that do not contain 27* an OHCI controller. A simple way to test whether a PC card has an 28* OHCI controller as an interface is to insert the PC card directly 29* into a laptop(or desktop) with a CardBus slot and if "lspci" shows 30* a new USB controller and "lsusb -v" shows a new OHCI Host Controller 31* then there is a good chance that the U132 adapter will support the 32* PC card.(you also need the specific client driver for the PC card) 33* 34* Please inform the Author and Maintainer about any PC cards that 35* contain OHCI Host Controller and work when directly connected to 36* an embedded CardBus slot but do not work when they are connected 37* via an ELAN U132 adapter. 38* 39* The driver consists of two modules, the "ftdi-u132" module is 40* a USB client driver that interfaces to the FTDI chip within 41* the U132 adapter manufactured by Elan Digital Systems, and the 42* "u132-hcd" module is a USB host controller driver that talks 43* to the OHCI controller within CardBus card that are inserted 44* in the U132 adapter. 45* 46* The "ftdi-u132" module should be loaded automatically by the 47* hot plug system when the U132 adapter is plugged in. The module 48* initialises the adapter which mostly consists of synchronising 49* the FTDI chip, before continuously polling the adapter to detect 50* PC card insertions. As soon as a PC card containing a recognised 51* OHCI controller is seen the "ftdi-u132" module explicitly requests 52* the kernel to load the "u132-hcd" module. 53* 54* The "ftdi-u132" module provides the interface to the inserted 55* PC card and the "u132-hcd" module uses the API to send and receive 56* data. The API features call-backs, so that part of the "u132-hcd" 57* module code will run in the context of one of the kernel threads 58* of the "ftdi-u132" module. 59* 60*/ 61int ftdi_elan_switch_on_diagnostics(int number); 62void ftdi_elan_gone_away(struct platform_device *pdev); 63void start_usb_lock_device_tracing(void); 64struct u132_platform_data { 65 u16 vendor; 66 u16 device; 67 u8 potpg; 68 void (*port_power) (struct device *dev, int is_on); 69 void (*reset) (struct device *dev); 70}; 71int usb_ftdi_elan_edset_single(struct platform_device *pdev, u8 ed_number, 72 void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, 73 void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, 74 int toggle_bits, int error_count, int condition_code, int repeat_number, 75 int halted, int skipped, int actual, int non_null)); 76int usb_ftdi_elan_edset_output(struct platform_device *pdev, u8 ed_number, 77 void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, 78 void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, 79 int toggle_bits, int error_count, int condition_code, int repeat_number, 80 int halted, int skipped, int actual, int non_null)); 81int usb_ftdi_elan_edset_empty(struct platform_device *pdev, u8 ed_number, 82 void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, 83 void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, 84 int toggle_bits, int error_count, int condition_code, int repeat_number, 85 int halted, int skipped, int actual, int non_null)); 86int usb_ftdi_elan_edset_input(struct platform_device *pdev, u8 ed_number, 87 void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, 88 void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, 89 int toggle_bits, int error_count, int condition_code, int repeat_number, 90 int halted, int skipped, int actual, int non_null)); 91int usb_ftdi_elan_edset_setup(struct platform_device *pdev, u8 ed_number, 92 void *endp, struct urb *urb, u8 address, u8 ep_number, u8 toggle_bits, 93 void (*callback) (void *endp, struct urb *urb, u8 *buf, int len, 94 int toggle_bits, int error_count, int condition_code, int repeat_number, 95 int halted, int skipped, int actual, int non_null)); 96int usb_ftdi_elan_edset_flush(struct platform_device *pdev, u8 ed_number, 97 void *endp); 98int usb_ftdi_elan_read_pcimem(struct platform_device *pdev, int mem_offset, 99 u8 width, u32 *data); 100int usb_ftdi_elan_write_pcimem(struct platform_device *pdev, int mem_offset, 101 u8 width, u32 data); 102
