ALSA: hda/hdmi - apply Haswell fix-ups to Skylake display codec

2015-08-27T17:26:04+00:00

[ Upstream commit 432ac1a2c028acb289d90f918e3a7b79e4ac8c07 ]

Skylake and Haswell have the same behavior on display audio. So this patch
applys Haswell fix-ups to Skylake.

ALSA: hda - Fix MacBook Pro 5,2 quirk

2015-08-27T17:25:42+00:00

[ Upstream commit 649ccd08534ee26deb2e5b08509800d0e95167f5 ]

MacBook Pro 5,2 with ALC889 codec had already a fixup entry, but this
seems not working correctly, a fix for pin NID 0x15 is needed in
addition.  It's equivalent with the fixup for MacBook Air 1,1, so use
this instead.

ALSA: usb-audio: Add MIDI support for Steinberg MI2/MI4

2015-08-27T17:25:41+00:00

[ Upstream commit 0689a86ae814f39af94a9736a0a5426dd82eb107 ]

The Steinberg MI2 and MI4 interfaces are compatible with the USB class
audio spec, but the MIDI part of the devices is reported as a vendor
specific interface.

This patch adds entries to quirks-table.h to recognize the MIDI
endpoints. Audio functionality was already working and is unaffected by
this change.

ALSA: fireworks/firewire-lib: add support for recent firmware quirk

2015-08-27T17:25:29+00:00

[ Upstream commit 18f5ed365d3f188a91149d528c853000330a4a58 ]

Fireworks uses TSB43CB43(IceLynx-Micro) as its IEC 61883-1/6 interface.
This chip includes ARM7 core, and loads and runs program. The firmware
is stored in on-board memory and loaded every powering-on from it.

Echo Audio ships several versions of firmwares for each model. These
firmwares have each quirk and the quirk changes a sequence of packets.

As long as I investigated, AudioFire2/AudioFire4/AudioFirePre8 have a
quirk to transfer a first packet with 0x02 in its dbc field. This causes
ALSA Fireworks driver to detect discontinuity. In this case, firmware
version 5.7.0, 5.7.3 and 5.8.0 are used.

(AudioFire2 with firmware version 5.7.)

$ dmesg
snd-fireworks fw1.0: Detect discontinuity of CIP: 00 02

These models, AudioFire8 (since Jul 2009 ) and Gibson Robot Interface
Pack series uses the same ARM binary as their firmware. Thus, this
quirk may be observed among them.

This commit adds a new member for AMDTP structure. This member represents
the value of dbc field in a first AMDTP packet. Drivers can set it with
a preferred value according to model's quirk.

Smatch complains that we have nested checks for "spdif_present".  It
turns out the current behavior isn't correct, we should remove the first
check and keep the second.

The DAPM lock must be held when accessing the DAPM graph status through
sysfs or debugfs, otherwise concurrent changes to the graph can result in
undefined behaviour.
