[PATCH v2 0/5] Few audio fixes on Tegra platforms
by Sameer Pujar 13 Jul '23

13 Jul '23

This series fixes some of the issues which were observed during an attempt to enhance automated test coverage on Jetson AGX Orin. Below is a short summary of the issues and fixes: * Sample rate coversion failures above 48kHz. * AMX and ADX test cases failures due to incorrect byte mask. * Atomic sleep in RT5640 codec which is present on Jetson AGX Orin. * AHUB clock fixes on Tegra234 and previous chips. * Minor cleanups in ASRC and AHUB driver. Changelog ========= v1 -> v2: --------- * Few patches got accepted in the original (v1) series. Now v2 addresses comments for remaining patches. * AMX/ADX byte map fix patch is updated with more details in the commit message and added TODO item in the driver to improve the logic. * For RT5640 codec patch, the threaded IRQ is used for only for rt5640_irq() and rt5640_jd_gpio_irq() is left untouched.

[PATCH v2 0/4] ASoC: rt5677: Refactor GPIO and use device_get_match_data()
by Andy Shevchenko 12 Jul '23

12 Jul '23

The code can be simplified with refactored GPIO parts and with use of device_get_match_data(). Besides that couple of additional changes, one for maintenance and one for making IRQ domain agnostic (not being pinned to OF).

[PATCH v2 00/37] ALSA: Add MIDI 2.0 support
by Takashi Iwai 12 Jul '23

12 Jul '23

Hi, this is a revised patch set for adding the support of MIDI 2.0 functionality. Only a few minor updates since v1 as below: * Bump CTL protocol version to 2.0.9 * Add two more ioctls for control API to receive UMP EP and block info * Minor compile warning fixes * Documentation fix and addition of two new ioctls * Put acks The latest code is found in topic/midi20 branch of sound git tree. And below is the cover letter of v1, which is still valid: Hi, this is a (largish) patch set for adding the support of MIDI 2.0 functionality, mainly targeted for USB devices. MIDI 2.0 is a complete overhaul of the 40-years old MIDI 1.0. Unlike MIDI 1.0 byte stream, MIDI 2.0 uses packets in 32bit words for Universal MIDI Packet (UMP) protocol. It supports both MIDI 1.0 commands for compatibility and the extended MIDI 2.0 commands for higher resolutions and more functions. For supporting the UMP, the patch set extends the existing ALSA rawmidi and sequencer interfaces, and adds the USB MIDI 2.0 support to the standard USB-audio driver. The rawmidi for UMP has a different device name (/dev/snd/umpC*D*) and it reads/writes UMP packet data in 32bit CPU-native endianness. For the old MIDI 1.0 applications, the legacy rawmidi interface is provided, too. As default, USB-audio driver will take the alternate setting for MIDI 2.0 interface, and the compatibility with MIDI 1.0 is provided via the rawmidi common layer. However, user may let the driver falling back to the old MIDI 1.0 interface by a module option, too. A UMP-capable rawmidi device can create the corresponding ALSA sequencer client(s) to support the UMP Endpoint and UMP Group connections. As a nature of ALSA sequencer, arbitrary connections between clients/ports are allowed, and the ALSA sequencer core performs the automatic conversions for the connections between a new UMP sequencer client and a legacy MIDI 1.0 sequencer client. It allows the existing application to use MIDI 2.0 devices without changes. The MIDI-CI, which is another major extension in MIDI 2.0, isn't covered by this patch set. It would be implemented rather in user-space. Roughly speaking, the first half of this patch set is for extending the rawmidi and USB-audio, and the second half is for extending the ALSA sequencer interface. The patch set is based on 6.4-rc2 kernel, but all patches can be cleanly applicable on 6.2 and 6.3 kernels, too (while 6.1 and older kernels would need minor adjustment for uapi header changes). The updates for alsa-lib and alsa-utils will follow shortly later. The author thanks members of MIDI Association OS/API Working Group, especially Andrew Mee, for great helps for the initial design and debugging / testing the drivers.
