treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 345

2019-06-05T15:37:08Z

Based on 1 normalized pattern(s): licensed under the terms of the gnu general public license version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 88 file(s).

ALSA: firewire: Remove superfluous snd_info_register() calls

2019-02-06T17:11:38Z

The calls of snd_info_register() are superfluous and should be avoided at the procfs creation time. They are called at the end of the whole initialization via snd_card_register(). This patch drops such superfluous calls. Reviewed-by: Takashi Sakamoto Tested-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

sound: Use octal not symbolic permissions

Convert the S_ symbolic permissions to their octal equivalents as using octal and not symbolic permissions is preferred by many as more readable. see: https://lkml.org/lkml/2016/8/2/1945 Done with automated conversion via: $ ./scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace Miscellanea: o Wrapped one multi-line call to a single line Signed-off-by: Joe Perches Acked-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: dice: add proc node for stream formation

2018-05-02T14:01:53Z

Products with DICE interface in market can support variable stream formats for three levels of sampling transmission frequencies. To record these formats, a proxy structure got several fields in former commit. This commit adds a proc node to output the stream formats for debugging purpose.

ALSA: dice: add 'firewire' directory for proc nodes

2018-05-02T14:01:51Z

Unlike the other drivers in ALSA firewire stack, ALSA dice driver does't create 'firewire' directory for proc nodes because it has 'dice' node only. But this is inconvenient because I have a plan to add another proc node to output available stream formats from cache. This commit let the driver to create the directory and put 'dice' node into it.

ALSA: dice: improve support for ancient firmware for DICE

2018-04-24T15:18:59Z

In early stage of firmware SDK, DICE seems to lose its backward compatibility due to some registers on global address section. I found this with Alesis Multimix 12 FireWire with ancient firmware (approx. shipped version). According to retrieved log from the unit, global section has 96 byte space. On the other hand, current version of ALSA dice driver assumes that all of supported unit has at least 100 byte space. $ ./firewire-request /dev/fw1 read 0xffffe0000000 28 result: 000: 00 00 00 0a 00 00 00 18 00 00 00 22 00 00 00 8a result: 010: 00 00 00 ac 00 00 01 12 00 00 00 00 00 00 00 00 result: 020: 00 00 00 00 00 00 00 00 This commit adds support for the ancient firmware. Check of global section is loosened to accept the smaller space. The lack of information is already compensated by hard-coded parameters. I experienced that the latest version of Windows driver for this model can't handle this unit, too. This means that TCAT releases firmware SDK without backward compatibility for the ancient firmware. Below list is a early history of driver/firmware package released by Alesis. I investigated on wayback machine on Internet Archive: * Unknown: PAL v1.0.41.2, firmware v1.0.3 * Mar 2006: PAL v1.54.0, firmware v1.0.4 * Dec 2006: PAL v2.0.0.2, firmware v2.0 * Jun 2007: PAL v3.0.41.5, firmware v2.0 * Jul 2007: PAL v3.0.56.2. firmware v2.0 * Jan 2008: PAL v3.0.81.1080, firmware v2.0 If I can assume that firmware version is the same as DICE version, DICE version for the issued firmware may be v1.0.3. According to code base of userspace driver project (FFADO), I can read DICE v1.0.4 supports global space larger than 100 byte. I guess the smaller space of global section is a feature of DICE v1.0.3.

ALSA: dice: fix wrong offsets for Dice interface

2015-03-01T09:49:06Z

For received packet stream, the offset of 'RX_SEQ_START' locates after the offset of 'RX_NUMBER_MIDI', although current macro and proc output includes wrong offsets. Fortunately, this bug doesn't affect streaming functionality because these macro is not used. This commit fixes these wrong macro and outputs.
