tty: move a number of tty drivers from drivers/char/ to drivers/tty/
As planned by Arnd Bergmann, this moves the following drivers from drivers/char/ to drivers/tty/ as that's where they really belong: amiserial nozomi synclink rocket cyclades moxa mxser isicom bfin_jtag_comm Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

- * Kernel Synchronization:
- *
- * This driver has 2 kernel control paths - exception handlers (calls into the driver
- * from user mode) and the timer bottom half (tasklet). This is a polled driver, interrupts
- * are not used.
- *
- * Critical data:
- * - rp_table[], accessed through passed "info" pointers, is a global (static) array of
- * serial port state information and the xmit_buf circular buffer. Protected by
- * a per port spinlock.
- * - xmit_flags[], an array of ints indexed by line (port) number, indicating that there
- * is data to be transmitted. Protected by atomic bit operations.
- * - rp_num_ports, int indicating number of open ports, protected by atomic operations.
- *
- * rp_write() and rp_write_char() functions use a per port semaphore to protect against
- * simultaneous access to the same port by more than one process.

- CONTROLLER_T *CtlP; Ptr to controller structure
- int CtlNum; Controller number
- ByteIO_t MudbacIO; Mudbac base I/O address.
- ByteIO_t *AiopIOList; List of I/O addresses for each AIOP.
- This list must be in the order the AIOPs will be found on the
- controller. Once an AIOP in the list is not found, it is
- assumed that there are no more AIOPs on the controller.
- int AiopIOListSize; Number of addresses in AiopIOList
- int IRQNum; Interrupt Request number. Can be any of the following:
- 0: Disable global interrupts
- 3: IRQ 3
- 4: IRQ 4
- 5: IRQ 5
- 9: IRQ 9
- 10: IRQ 10
- 11: IRQ 11
- 12: IRQ 12
- 15: IRQ 15
- Byte_t Frequency: A flag identifying the frequency
- of the periodic interrupt, can be any one of the following:
- FREQ_DIS - periodic interrupt disabled
- FREQ_137HZ - 137 Hertz
- FREQ_69HZ - 69 Hertz
- FREQ_34HZ - 34 Hertz
- FREQ_17HZ - 17 Hertz
- FREQ_9HZ - 9 Hertz
- FREQ_4HZ - 4 Hertz
- If IRQNum is set to 0 the Frequency parameter is
- overidden, it is forced to a value of FREQ_DIS.
- int PeriodicOnly: 1 if all interrupts except the periodic
- interrupt are to be blocked.
- 0 is both the periodic interrupt and
- other channel interrupts are allowed.
- If IRQNum is set to 0 the PeriodicOnly parameter is
- overidden, it is forced to a value of 0.
-Return: int: Number of AIOPs on the controller, or CTLID_NULL if controller
- initialization failed.
-
-Comments:
- If periodic interrupts are to be disabled but AIOP interrupts
- are allowed, set Frequency to FREQ_DIS and PeriodicOnly to 0.
-
- If interrupts are to be completely disabled set IRQNum to 0.
-
- Setting Frequency to FREQ_DIS and PeriodicOnly to 1 is an
- invalid combination.
-
- This function performs initialization of global interrupt modes,
- but it does not actually enable global interrupts. To enable
- and disable global interrupts use functions sEnGlobalInt() and
- sDisGlobalInt(). Enabling of global interrupts is normally not
- done until all other initializations are complete.
-
- Even if interrupts are globally enabled, they must also be
- individually enabled for each channel that is to generate
- interrupts.
-
-Warnings: No range checking on any of the parameters is done.
-
- No context switches are allowed while executing this function.
-
- After this function all AIOPs on the controller are disabled,
- they can be enabled with sEnAiop().

- This list must be in the order the AIOPs will be found on the

- int AiopIOListSize; Number of addresses in AiopIOList

- Byte_t Frequency: A flag identifying the frequency
- of the periodic interrupt, can be any one of the following:
- FREQ_DIS - periodic interrupt disabled
- FREQ_137HZ - 137 Hertz
- FREQ_69HZ - 69 Hertz
- FREQ_34HZ - 34 Hertz
- FREQ_17HZ - 17 Hertz
- FREQ_9HZ - 9 Hertz
- FREQ_4HZ - 4 Hertz
- If IRQNum is set to 0 the Frequency parameter is
- overidden, it is forced to a value of FREQ_DIS.
- int PeriodicOnly: 1 if all interrupts except the periodic
- interrupt are to be blocked.
- 0 is both the periodic interrupt and
- other channel interrupts are allowed.
- If IRQNum is set to 0 the PeriodicOnly parameter is
- overidden, it is forced to a value of 0.
-Return: int: Number of AIOPs on the controller, or CTLID_NULL if controller
- initialization failed.
-
-Comments:
- If periodic interrupts are to be disabled but AIOP interrupts
- are allowed, set Frequency to FREQ_DIS and PeriodicOnly to 0.
-
- If interrupts are to be completely disabled set IRQNum to 0.
-
- Setting Frequency to FREQ_DIS and PeriodicOnly to 1 is an
- invalid combination.
-
- This function performs initialization of global interrupt modes,
- but it does not actually enable global interrupts. To enable
- and disable global interrupts use functions sEnGlobalInt() and
- sDisGlobalInt(). Enabling of global interrupts is normally not
- done until all other initializations are complete.
-
- Even if interrupts are globally enabled, they must also be
- individually enabled for each channel that is to generate
- interrupts.
-
-Warnings: No range checking on any of the parameters is done.
-
- No context switches are allowed while executing this function.
-
- After this function all AIOPs on the controller are disabled,
- they can be enabled with sEnAiop().
