One of the many faults of the QinHeng CH345 USB MIDI interface chip is
that it does not handle received SysEx messages correctly -- every second
event packet has a wrong code index number, which is the one from the last
seen message, instead of 4.  For example, the two messages "FE F0 01 02 03
04 05 06 07 08 09 0A 0B 0C 0D 0E F7" result in the following event
packets:

correct:       CH345:
0F FE 00 00    0F FE 00 00
04 F0 01 02    04 F0 01 02
04 03 04 05    0F 03 04 05
04 06 07 08    04 06 07 08
04 09 0A 0B    0F 09 0A 0B
04 0C 0D 0E    04 0C 0D 0E
05 F7 00 00    05 F7 00 00

A class-compliant driver must interpret an event packet with CIN 15 as
having a single data byte, so the other two bytes would be ignored.  The
message received by the host would then be missing two bytes out of six;
in this example, "F0 01 02 03 06 07 08 09 0C 0D 0E F7".

These corrupted SysEx event packages contain only data bytes, while the
CH345 uses event packets with a correct CIN value only for messages with
a status byte, so it is possible to distinguish between these two cases by
checking for the presence of this status byte.

(Other bugs in the CH345's input handling, such as the corruption resulting
from running status, cannot be worked around.)

The CH345 USB MIDI chip has two output ports.  However, they are
multiplexed through one pin, and the number of ports cannot be reduced
even for hardware that implements only one connector, so for those
devices, data sent to either port ends up on the same hardware output.
This becomes a problem when both ports are used at the same time, as
longer MIDI commands (such as SysEx messages) are likely to be
interrupted by messages from the other port, and thus to get lost.

It would not be possible for the driver to detect how many ports the
device actually has, except that in practice, _all_ devices built with
the CH345 have only one port.  So we can just ignore the device's
descriptors, and hardcode one output port.

Commit a471fcde

 ("ALSA: dice: fix detection of Weiss devices") adds
a quirk of Weiss models. According to users' reports, Loud models also
have the similar quirk. They have 0x10 in the category field.

This commit adds support for Mackie Onyx Blackbird and Onyx-i series.
As long as I know, Dice-based models produced by
Focusrite/Alesis/PreSonus/M-Audio/TC Electronic have default value (0x04)
in their category field, thus it may be reasonable to add a condition
statement for Loud models, instead of removing the check of category value.

There are several sound drivers that 'select ZONE_DMA'.  This is
backwards as ZONE_DMA is an architecture capability exported to drivers.
Switch the polarity of the dependency to disable these drivers when the
architecture does not support ZONE_DMA.  This was discovered in the
context of testing/enabling devm_memremap_pages() which depends on
ZONE_DEVICE.  ZONE_DEVICE in turn depends on !ZONE_DMA.

The HDMI codec parser may create a phantom jack, but the helper
function snd_hda_jack_add_kctl() treats always as a normal jack.  This
is superfluous as the jack query is executed at each time the jack
sync is performed.

Since the HDMI codec parser is the only caller of this function, it's
easier to change back this directly calling the original
__snd_hda_jack_add_kctl() with phantom_jack parameter.

During the migration to HDA core code, we lost the workaround for 4k
BDL boundary.  The flag exists in the new hdac_bus, but it's never

Digi 002/003 family uses two ways to transfer MIDI messages. They're
different mechanisms, while it's better to handle the ways in different
ALSA rawmidi character devices because one character device has just a
set of operations.

This commit adds another rawmidi character device for control MIDI port. As
a result, first rawmidi character device is just for MIDI messages
transferred by isochronous packets.

Digi 002/003 family has two types of MIDI port; one is for physical MIDI
port and another is for MIDI control message. The former is transferred in
isochronous packet, and the latter is transferred by asynchronous
transaction. These transmission mechanisms are completely different, while
current ALSA digi00x driver defines a set of operations for them with
several condition statements. As a result, codes for the operation are
messy.

This commit adds a set of MIDI operation for control MIDI ports. In later
commit, it's applied as an operation for ALSA rawmidi character device.

We've had many reports that some Creative sound cards with CA0132
don't work well.  Some reported that it starts working after reloading
the module, while some reported it starts working when a 32bit kernel
is used.  All these facts seem implying that the chip fails to
communicate when the buffer is located in 64bit address.

This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT
flag to the corresponding PCI entries.  I casually had a chance to
test an SB Recon3D board, and indeed this seems helping.

Although this hasn't been tested on all Creative devices, it's safer
to assume that this restriction applies to the rest of them, too.  So
the flag is applied to all Creative entries.
