+ DO NOT ADD FIRMWARE TO THIS DIRECTORY.
+ ======================================
+
+This directory is only here to contain firmware images extracted from old
+device drivers which predate the common use of request_firmware().
+
+As we update those drivers to use request_firmware() and keep a clean
+separation between code and firmware, we put the extracted firmware
+here.

+Your commit should include an update to the WHENCE file clearly
+identifying the licence under which the firmware is available, and
+that it is redistributable. If the licence is long and involved, it's
+permitted to include it in a separate file and refer to it from the
+WHENCE file.
+
+Ideally, your commit should contain a Signed-Off-By: from someone
+authoritative on the licensing of the firmware in question (i.e. from
+within the company that owns the code).

+ *
+ * Firmware for the Keyspan PDA Serial Adapter, a USB serial port based on
+ * the EzUSB microcontroller.
+ *
+ * (C) Copyright 2000 Brian Warner <warner@lothar.com>
+ *
+ * This program is free software; you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License as published by
+ * the Free Software Foundation; either version 2 of the License, or
+ * (at your option) any later version.
+ *
+ * "Keyspan PDA Serial Adapter" is probably a copyright of Keyspan, the
+ * company.
+ *
+ * This serial adapter is basically an EzUSB chip and an RS-232 line driver
+ * in a little widget that has a DB-9 on one end and a USB plug on the other.
+ * It uses the EzUSB's internal UART0 (using the pins from Port C) and timer2
+ * as a baud-rate generator. The wiring is:
+ * PC0/RxD0 <- rxd (DB9 pin 2) PC4 <- dsr pin 6
+ * PC1/TxD0 -> txd pin 3 PC5 <- ri pin 9
+ * PC2 -> rts pin 7 PC6 <- dcd pin 1
+ * PC3 <- cts pin 8 PC7 -> dtr pin 4
+ * PB1 -> line driver standby
+ *
+ * The EzUSB register constants below come from their excellent documentation
+ * and sample code (which used to be available at www.anchorchips.com, but
+ * that has now been absorbed into Cypress' site and the CD-ROM contents
+ * don't appear to be available online anymore). If we get multiple
+ * EzUSB-based drivers into the kernel, it might be useful to pull them out
+ * into a separate .h file.
+ *
+ * THEORY OF OPERATION:
+ *
+ * There are two 256-byte ring buffers, one for tx, one for rx.
+ *
+ * EP2out is pure tx data. When it appears, the data is copied into the tx
+ * ring and serial transmission is started if it wasn't already running. The
+ * "tx buffer empty" interrupt may kick off another character if the ring
+ * still has data. If the host is tx-blocked because the ring filled up,
+ * it will request a "tx unthrottle" interrupt. If sending a serial character
+ * empties the ring below the desired threshold, we set a bit that will send
+ * up the tx unthrottle message as soon as the rx buffer becomes free.
+ *
+ * EP2in (interrupt) is used to send both rx chars and rx status messages
+ * (only "tx unthrottle" at this time) back up to the host. The first byte
+ * of the rx message indicates data (0) or status msg (1). Status messages
+ * are sent before any data.
+ *
+ * Incoming serial characters are put into the rx ring by the serial
+ * interrupt, and the EP2in buffer sent if it wasn't already in transit.
+ * When the EP2in buffer returns, the interrupt prompts us to send more
+ * rx chars (or status messages) if they are pending.
+ *
+ * Device control happens through "vendor specific" control messages on EP0.
+ * All messages are destined for the "Interface" (with the index always 0,
+ * so that if their two-port device might someday use similar firmware, we
+ * can use index=1 to refer to the second port). The messages defined are:
+ *
+ * bRequest = 0 : set baud/bits/parity
+ * 1 : unused
+ * 2 : reserved for setting HW flow control (CTSRTS)
+ * 3 : get/set "modem info" (pin states: DTR, RTS, DCD, RI, etc)
+ * 4 : set break (on/off)
+ * 5 : reserved for requesting interrupts on pin state change
+ * 6 : query buffer room or chars in tx buffer
+ * 7 : request tx unthrottle interrupt
+ *
+ * The host-side driver is set to recognize the device ID values stashed in
+ * serial EEPROM (0x06cd, 0x0103), program this firmware into place, then
+ * start it running. This firmware will use EzUSB's "renumeration" trick by
+ * simulating a bus disconnect, then reconnect with a different device ID
+ * (encoded in the desc_device descriptor below). The host driver then
+ * recognizes the new device ID and glues it to the real serial driver code.
+ *
+ * USEFUL DOCS:
+ * EzUSB Technical Reference Manual: <http://www.cypress.com/>
+ * 8051 manuals: everywhere, but try www.dalsemi.com because the EzUSB is
+ * basically the Dallas enhanced 8051 code. Remember that the EzUSB IO ports
+ * use totally different registers!
+ * USB 1.1 spec: www.usb.org
+ *
+ * HOW TO BUILD:
+ * gcc -x assembler-with-cpp -P -E -o keyspan_pda.asm keyspan_pda.s
+ * as31 -l keyspan_pda.asm
+ * mv keyspan_pda.obj keyspan_pda.hex
+ * perl ezusb_convert.pl keyspan_pda < keyspan_pda.hex > keyspan_pda_fw.h
+ * Get as31 from <http://www.pjrc.com/tech/8051/index.html>, and hack on it
+ * a bit to make it build.
+ *
+ * THANKS:
+ * Greg Kroah-Hartman, for coordinating the whole usb-serial thing.
+ * AnchorChips, for making such an incredibly useful little microcontroller.
+ * KeySpan, for making a handy, cheap ($40) widget that was so easy to take
+ * apart and trace with an ohmmeter.
+ *
+ * TODO:
+ * lots. grep for TODO. Interrupt safety needs stress-testing. Better flow
+ * control. Interrupting host upon change in DCD, etc, counting transitions.
+ * Need to find a safe device id to use (the one used by the Keyspan firmware
+ * under Windows would be ideal.. can anyone figure out what it is?). Parity.
+ * More baud rates. Oh, and the string-descriptor-length silicon bug
+ * workaround should be implemented, but I'm lazy, and the consequence is
+ * that the device name strings that show up in your kernel log will have
+ * lots of trailing binary garbage in them (appears as ????). Device strings
+ * should be made more accurate.
+ *
+ * Questions, bugs, patches to Brian.

+ *
+ * Firmware for the Keyspan PDA Serial Adapter, a USB serial port based on
+ * the EzUSB microcontroller.
+ *
+ * (C) Copyright 2000 Brian Warner <warner@lothar.com>
+ *
+ * This program is free software; you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License as published by
+ * the Free Software Foundation; either version 2 of the License, or
+ * (at your option) any later version.
+ *
+ * "Keyspan PDA Serial Adapter" is probably a copyright of Keyspan, the
+ * company.
+ *
+ * This serial adapter is basically an EzUSB chip and an RS-232 line driver
+ * in a little widget that has a DB-9 on one end and a USB plug on the other.
+ * It uses the EzUSB's internal UART0 (using the pins from Port C) and timer2
+ * as a baud-rate generator. The wiring is:
+ * PC0/RxD0 <- rxd (DB9 pin 2) PC4 <- dsr pin 6
+ * PC1/TxD0 -> txd pin 3 PC5 <- ri pin 9
+ * PC2 -> rts pin 7 PC6 <- dcd pin 1
+ * PC3 <- cts pin 8 PC7 -> dtr pin 4
+ * PB1 -> line driver standby
+ *
+ * The EzUSB register constants below come from their excellent documentation
+ * and sample code (which used to be available at www.anchorchips.com, but
+ * that has now been absorbed into Cypress' site and the CD-ROM contents
+ * don't appear to be available online anymore). If we get multiple
+ * EzUSB-based drivers into the kernel, it might be useful to pull them out
+ * into a separate .h file.
+ *
+ * THEORY OF OPERATION:
+ *
+ * There are two 256-byte ring buffers, one for tx, one for rx.
+ *
+ * EP2out is pure tx data. When it appears, the data is copied into the tx
+ * ring and serial transmission is started if it wasn't already running. The
+ * "tx buffer empty" interrupt may kick off another character if the ring
+ * still has data. If the host is tx-blocked because the ring filled up,
+ * it will request a "tx unthrottle" interrupt. If sending a serial character
+ * empties the ring below the desired threshold, we set a bit that will send
+ * up the tx unthrottle message as soon as the rx buffer becomes free.
+ *
+ * EP2in (interrupt) is used to send both rx chars and rx status messages
+ * (only "tx unthrottle" at this time) back up to the host. The first byte
+ * of the rx message indicates data (0) or status msg (1). Status messages
+ * are sent before any data.
+ *
+ * Incoming serial characters are put into the rx ring by the serial
+ * interrupt, and the EP2in buffer sent if it wasn't already in transit.
+ * When the EP2in buffer returns, the interrupt prompts us to send more
+ * rx chars (or status messages) if they are pending.
+ *
+ * Device control happens through "vendor specific" control messages on EP0.
+ * All messages are destined for the "Interface" (with the index always 0,
+ * so that if their two-port device might someday use similar firmware, we
+ * can use index=1 to refer to the second port). The messages defined are:
+ *
+ * bRequest = 0 : set baud/bits/parity
+ * 1 : unused
+ * 2 : reserved for setting HW flow control (CTSRTS)
+ * 3 : get/set "modem info" (pin states: DTR, RTS, DCD, RI, etc)
+ * 4 : set break (on/off)
+ * 5 : reserved for requesting interrupts on pin state change
+ * 6 : query buffer room or chars in tx buffer
+ * 7 : request tx unthrottle interrupt
+ *
+ * The host-side driver is set to recognize the device ID values stashed in
+ * serial EEPROM (0x06cd, 0x0103), program this firmware into place, then
+ * start it running. This firmware will use EzUSB's "renumeration" trick by
+ * simulating a bus disconnect, then reconnect with a different device ID
+ * (encoded in the desc_device descriptor below). The host driver then
+ * recognizes the new device ID and glues it to the real serial driver code.
+ *
+ * USEFUL DOCS:
+ * EzUSB Technical Reference Manual: <http://www.cypress.com/>
+ * 8051 manuals: everywhere, but try www.dalsemi.com because the EzUSB is
+ * basically the Dallas enhanced 8051 code. Remember that the EzUSB IO ports
+ * use totally different registers!
+ * USB 1.1 spec: www.usb.org
+ *
+ * HOW TO BUILD:
+ * gcc -x assembler-with-cpp -P -E -o keyspan_pda.asm keyspan_pda.s
+ * as31 -l keyspan_pda.asm
+ * mv keyspan_pda.obj keyspan_pda.hex
+ * perl ezusb_convert.pl keyspan_pda < keyspan_pda.hex > keyspan_pda_fw.h
+ * Get as31 from <http://www.pjrc.com/tech/8051/index.html>, and hack on it
+ * a bit to make it build.
+ *
+ * THANKS:
+ * Greg Kroah-Hartman, for coordinating the whole usb-serial thing.
+ * AnchorChips, for making such an incredibly useful little microcontroller.
+ * KeySpan, for making a handy, cheap ($40) widget that was so easy to take
+ * apart and trace with an ohmmeter.
+ *
+ * TODO:
+ * lots. grep for TODO. Interrupt safety needs stress-testing. Better flow
+ * control. Interrupting host upon change in DCD, etc, counting transitions.
+ * Need to find a safe device id to use (the one used by the Keyspan firmware
+ * under Windows would be ideal.. can anyone figure out what it is?). Parity.
+ * More baud rates. Oh, and the string-descriptor-length silicon bug
+ * workaround should be implemented, but I'm lazy, and the consequence is
+ * that the device name strings that show up in your kernel log will have
+ * lots of trailing binary garbage in them (appears as ????). Device strings
+ * should be made more accurate.
+ *
+ * Questions, bugs, patches to Brian.
