2021-10-26ALSA: line6: fix control and interrupt message timeoutsJohan Hovold
USB control and interrupt message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ.

2020-05-02ALSA: line6: hwdep: add support for O_NONBLOCK opening modeVasily Khoruzhick
Currently line6 hwdep interface ignores O_NONBLOCK flag when opening device and it renders it somewhat useless when using poll. Check for O_NONBLOCK flag when opening device and don't block read() if it is set.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.3 This is a very big update, mainly thanks to Morimoto-san's refactoring work and some fairly large new drivers. - Lots more work on moving towards a component based framework from Morimoto-san. - Support for force disconnecting muxes from Jerome Brunet. - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant CX2072X, Realtek RT1011 and RT1308.

2019-05-28ALSA: line6: Drop superfluous timer helper functionTakashi Iwai
Now all timer usages in line6 drivers are gone, we can get rid of some helper macro and function that became superfluous. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-05-28ALSA: line6: Assure canceling delayed work at disconnectionTakashi Iwai
The current code performs the cancel of a delayed work at the late stage of disconnection procedure, which may lead to the access to the already cleared state. This patch assures to call cancel_delayed_work_sync() at the beginning of the disconnection procedure for avoiding that race. The delayed work object is now assigned in the common line6 object instead of its derivative, so that we can call cancel_delayed_work_sync(). Along with the change, the startup function is called via the new callback instead. This will make it easier to port other LINE6 drivers to use the delayed work for startup in later patches.

2017-10-17ALSA: usb-audio: Convert timers to use timer_setup()Kees Cook

2017-06-20ALSA: line6: remove unnecessary initialization to PODHD500XHans P. Möller Ebner
Remove Initialization from POD HD500X because it's not needed. Every time the device is connected dmesg gives the following output: "receive length failed (error -11)". To solve this problem, another flags is introduced (LINE6_CAP_CONTROL_INFO) and it is only used for PODX3 in: sysfs entries, call podhd_startup_finalize(pod) and disconnection. With this patch the error disappear. Signed-off-by: Hans P. Moller <hmoller@uc.cl> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-11-29ALSA: line6: Claim pod x3 usb data interfaceAndrej Krutak
Userspace apps have to claim USB interfaces before using endpoints in them (drivers/usb/core/devio.c:checkintf()). It's a lock mechanism so that two "drivers" don't steal data from each other. Kernel drivers don't have to claim interfaces to work - but they should, to lock out userspace. While there, fix line6_properties struct to match checkpatch.pl.

2016-09-19ALSA: line6: Add hwdep interface to access the POD control messagesAndrej Krutak
We must do it this way, because e.g. POD X3 won't play any sound unless the host listens on the bulk EP, so we cannot export it only via libusb. The driver currently doesn't use the bulk EP messages in other way, in future it could e.g. sense/modify volume(s).

2016-09-19ALSA: line6: Allow processing of raw incoming messagesAndrej Krutak

2016-09-19ALSA: line6: Distinguish device init (ctrl EP) and MIDI data transfer (int EP)Andrej Krutak
POD X3 can initialize similarly to older PODs, but it doesn't have the MIDI interface. Instead, configuration is done via proprietary bulk EP messages. Signed-off-by: Andrej Krutak <dev@andree.sk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-09-19ALSA: line6: Add LINE6_CAP_IN_NEEDS_OUT, a void playback stream during captureAndrej Krutak
E.g. POD X3 seems to require playback data to be sent to it to generate capture data. Otherwise the device stalls and doesn't send any more capture data until it's reset. Signed-off-by: Andrej Krutak <dev@andree.sk> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2016-09-19ALSA: line6: Add high-speed USB supportAndrej Krutak
This has two parts: * intervals_per_second setup (high speed needs 8000, instead of 1000) * iso_buffers setup (count of iso buffers depends on USB speed, 2 is not enough for high speed) Signed-off-by: Andrej Krutak <dev@andree.sk> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-02-12ALSA: line6: Improve line6_read/write_data() interfacesChris Rorvick

The interface argument is used just for retrieving the assigned device, which can be already found in line6->ifcdev. Drop them from the callbacks. Also, pass the usb id to private_init so that the driver can deal with it there. This is a preliminary work for the further cleanup to move the whole allocation into driver.c.
