The mwave driver has its own macros for the BOOLEAN type and the
TRUE/FALSE values. This is redundant because the kernel already
has bool/true/false, and it clashes with the ACPI headers that
also define these types. The linux/acpi.h header is now included
implicitly from mwave through the mc146818rtc.h header, as
reported by Stephen Rothwell:
In file included from drivers/char/mwave/smapi.c:51:0:
drivers/char/mwave/smapi.h:52:0: warning: "TRUE" redefined
#define TRUE 1
^
In file included from include/acpi/acpi.h:58:0,
from include/linux/acpi.h:33,
from include/linux/mc146818rtc.h:21,
from drivers/char/mwave/smapi.c:50:
include/acpi/actypes.h:438:0: note: this is the location of the previous definition
#define TRUE (1 == 1)
^
This removes the private types from mwave and uses the standard
types instead.

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_debug=value, where value is bitwise OR of trace flags:
0x0001 mwavedd api tracing
0x0002 smapi api tracing
0x0004 3780i tracing
0x0008 tp3780i tracing
Tracing only occurs if the driver has been compiled with the
MW_TRACE macro #defined (i.e. let ccflags-y := -DMW_TRACE
in the Makefile).
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
