@@ -56,3 +56,12 @@ This file details changes in 2.6 which affect PCMCIA card driver authors:
    memory regions in-use. The name argument should be a pointer to
    your driver name. Eg, for pcnet_cs, name should point to the
    string "pcnet_cs".
+
+* CardServices is gone
+  CardServices() in 2.4 is just a big switch statement to call various
+  services.  In 2.6, all of those entry points are exported and called
+  directly (except for pcmcia_report_error(), just use cs_error() instead).
+
+* struct pcmcia_driver
+  You need to use struct pcmcia_driver and pcmcia_{un,}register_driver
+  instead of {un,}register_pccard_driver

+ *
+ * Based entirely upon drivers/sbus/audio/dbri.c which is:
+ * Copyright (C) 1997 Rudolf Koenig (rfkoenig@immd4.informatik.uni-erlangen.de)
+ * Copyright (C) 1998, 1999 Brent Baccala (baccala@freesoft.org)
+ *
+ * This is the lowlevel driver for the DBRI & MMCODEC duo used for ISDN & AUDIO
+ * on Sun SPARCstation 10, 20, LX and Voyager models.
+ *
+ * - DBRI: AT&T T5900FX Dual Basic Rates ISDN Interface. It is a 32 channel
+ *   data time multiplexer with ISDN support (aka T7259)
+ *   Interfaces: SBus,ISDN NT & TE, CHI, 4 bits parallel.
+ *   CHI: (spelled ki) Concentration Highway Interface (AT&T or Intel bus ?).
+ *   Documentation:
+ *   - "STP 4000SBus Dual Basic Rate ISDN (DBRI) Tranceiver" from
+ *     Sparc Technology Business (courtesy of Sun Support)
+ *   - Data sheet of the T7903, a newer but very similar ISA bus equivalent
+ *     available from the Lucent (formarly AT&T microelectronics) home
+ *     page.
+ *   - http://www.freesoft.org/Linux/DBRI/
+ * - MMCODEC: Crystal Semiconductor CS4215 16 bit Multimedia Audio Codec
+ *   Interfaces: CHI, Audio In & Out, 2 bits parallel
+ *   Documentation: from the Crystal Semiconductor home page.
+ *
+ * The DBRI is a 32 pipe machine, each pipe can transfer some bits between
+ * memory and a serial device (long pipes, nr 0-15) or between two serial
+ * devices (short pipes, nr 16-31), or simply send a fixed data to a serial
+ * device (short pipes).
+ * A timeslot defines the bit-offset and nr of bits read from a serial device.
+ * The timeslots are linked to 6 circular lists, one for each direction for
+ * each serial device (NT,TE,CHI). A timeslot is associated to 1 or 2 pipes
+ * (the second one is a monitor/tee pipe, valid only for serial input).
+ *
+ * The mmcodec is connected via the CHI bus and needs the data & some
+ * parameters (volume, balance, output selection) timemultiplexed in 8 byte
+ * chunks. It also has a control mode, which serves for audio format setting.
+ *
+ * Looking at the CS4215 data sheet it is easy to set up 2 or 4 codecs on
+ * the same CHI bus, so I thought perhaps it is possible to use the onboard
+ * & the speakerbox codec simultanously, giving 2 (not very independent :-)
+ * audio devices. But the SUN HW group decided against it, at least on my
+ * LX the speakerbox connector has at least 1 pin missing and 1 wrongly
+ * connected.

+****************************************************************************
+************** DBRI initialization and command synchronization *************
+****************************************************************************
+
+Commands are sent to the DBRI by building a list of them in memory,
+then writing the address of the first list item to DBRI register 8.
+The list is terminated with a WAIT command, which can generate a
+CPU interrupt if required.
+
+Since the DBRI can run in parallel with the CPU, several means of
+synchronization present themselves.  The original scheme (Rudolf's)
+was to set a flag when we "cmdlock"ed the DBRI, clear the flag when
+an interrupt signaled completion, and wait on a wait_queue if a routine
+attempted to cmdlock while the flag was set.  The problems arose when
+we tried to cmdlock from inside an interrupt handler, which might
+cause scheduling in an interrupt (if we waited), etc, etc
+
+A more sophisticated scheme might involve a circular command buffer
+or an array of command buffers.  A routine could fill one with
+commands and link it onto a list.  When a interrupt signaled
+completion of the current command buffer, look on the list for
+the next one.
+
+I've decided to implement something much simpler - after each command,
+the CPU waits for the DBRI to finish the command by polling the P bit
+in DBRI register 0.  I've tried to implement this in such a way
+that might make implementing a more sophisticated scheme easier.
+
+Every time a routine wants to write commands to the DBRI, it must
+first call dbri_cmdlock() and get an initial pointer into dbri->dma->cmd
+in return.  After the commands have been writen, dbri_cmdsend() is
+called with the final pointer value.

+The DBRI communicates with the CPU mainly via a circular interrupt
+buffer.  When an interrupt is signaled, the CPU walks through the
+buffer and calls dbri_process_one_interrupt() for each interrupt word.
+Complicated interrupts are handled by dedicated functions (which
+appear first in this file).  Any pending interrupts can be serviced by
+calling dbri_process_interrupt_buffer(), which works even if the CPU's
+interrupts are disabled.  This function is used by dbri_cmdsend()
+to make sure we're synced up with the chip after each command sequence,
+even if we're running cli'ed.
