Subject: [PATCH v2] char/mwave: drop it
When I tried to clean up the driver a bit, Arnd noted:
> According to thinkwiki.de, the 3780i modem was only used in a
> couple of Thinkpad models that are now over 25 years old, using
> Pentium II processors, and they all have a physical RS232 port
> that can be used to connect an external modem instead.
>
> Maybe we can just retire this driver?
So instead of the clean up, drop the driver altogether.

I am not sure what you meant by "retire this driver"? If dropping, this
is the patch :).

- help
- The ACP modem (Mwave) for Linux is a WinModem. It is composed of a
- kernel driver and a user level application. Together these components
- support direct attachment to public switched telephone networks (PSTNs)
- and support selected world wide countries.
-
- This version of the ACP Modem driver supports the IBM Thinkpad 600E,
- 600, and 770 that include on board ACP modem hardware.
-
- The modem also supports the standard communications port interface
- (ttySx) and is compatible with the Hayes AT Command Set.
-
- The user level application needed to use this driver can be found at
- the IBM Linux Technology Center (LTC) web site:
- <http://www.ibm.com/linux/ltc/>.
-
- If you own one of the above IBM Thinkpads which has the Mwave chipset
- in it, say Y.

-Module options
---------------
-
-The mwave module takes the following options. Note that these options
-are not saved by the BIOS and so do not persist after unload and reload.
-
- mwave_3780i_irq=5/7/10/11/15
- If the dsp irq has not been setup and stored in bios by the
- thinkpad configuration utility then this parameter allows the
- irq used by the dsp to be configured.
-
- mwave_3780i_io=0x130/0x350/0x0070/0xDB0
- If the dsp io range has not been setup and stored in bios by the
- thinkpad configuration utility then this parameter allows the
- io range used by the dsp to be configured.
-
- mwave_uart_irq=3/4
- If the mwave's uart irq has not been setup and stored in bios by the
- thinkpad configuration utility then this parameter allows the
- irq used by the mwave uart to be configured.
-
- mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
- If the uart io range has not been setup and stored in bios by the
- thinkpad configuration utility then this parameter allows the
- io range used by the mwave uart to be configured.
-
-Example to enable the 3780i DSP using ttyS1 resources:
-
- insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
-
-Accessing the driver
---------------------
-
-You must also create a node for the driver:
- mkdir -p /dev/modems
- mknod --mode=660 /dev/modems/mwave c 10 219
-
