[ALSA] Add MPU401_INFO_NO_ACK bitflag

2008-04-29T17:01:56+00:00

Added MPU401_INFO_NO_ACK bitflag to ignore the ACK check for UART
commands.  VT172x doesn't handle ACK commands, for example.

[ALSA] Define MPU401 registers in sound/mpu401_uart.h

2008-04-24T10:38:22+00:00

Define some MPU401 registers in sound/mpu401_uart.h so that other
drivers can refer to them.

[ALSA] mpu401: reduce tx loop timeout

2008-04-24T10:00:15+00:00

Reduce the number of times to check for a non-empty Tx FIFO from 100 to
2 because there is no MPU-401 implementation that needs more than one or
two reads to determine the actual FIFO status.

[ALSA] Remove sound/driver.h

2008-01-31T16:29:48+00:00

This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.

[ALSA] mpu401: fix recursive locking in timer

2007-11-19T17:38:32+00:00

When the output and input ports are used at the same time, the timer can
be interrupted by the hardware interrupt, so we have to disable
interrupts when we take a lock in the timer.

[ALSA] mpu-401: remove MPU401_INFO_UART_ONLY flag

2007-10-16T14:51:14+00:00

Since the last patch made the ENTER_UART command optional, the
enter_uart option and its corresponding flag have become superfluous.
The uart_enter option remains for backward compatibility but just prints
a warning when used.

[ALSA] mpu-401: do not require an ACK byte for the ENTER_UART command

2007-10-16T14:51:12+00:00

The original MPU-401 does not send an ACK byte after processing the
ENTER_UART command, so we better do not try to wait for it.
Many clones get this wrong and do send an ACK, but when interpreting it
as MIDI, it is just a harmless Active Sensing message, and it is likely
to be read and discarded by the interrupt handler before the MIDI input
device is triggered.

[ALSA] more section mismatches

2007-07-20T09:11:34+00:00

Something about __init_or_module isn't working as expected (?).

Fix shared init/exit code helper:
