[PATCH v2 0/8] ASoC: SOF: Add support for Mediatek MT8195
by Daniel Baluta 26 Nov '21

26 Nov '21

From: Daniel Baluta <daniel.baluta(a)nxp.com> This adds sound open firmware driver support for MT8915 platform. Changes since v1: - removed AMD patches since they were already applied - fixed compilation error reported by Mark, generated by the fact that mt8195_run was declared too early in the series.

[PATCH v1 00/20] Support HDMI audio on NVIDIA Tegra20
by Dmitry Osipenko 26 Nov '21

26 Nov '21

This series revives Tegra20 S/PDIF driver which was upstreamed long time ago, but never was used. It also turns Tegra DRM HDMI driver into HDMI audio CODEC provider. Finally, HDMI audio is enabled in device-trees. For now the audio is enable only for Acer A500 tablet and Toshiba AC100 netbook because they're already supported by upstream, later on ASUS TF101 tablet will join them. I based S/PDIF patches on Arnd's Bergmann patch from a separate series [1] that removes obsolete slave_id. This eases merging of the patches by removing the merge conflict.

[PATCH v2] ASoC: dt-bindings: davinci-mcasp: convert McASP bindings to yaml schema

Convert the bindings for McASP controllers for TI SOCs from txt to YAML schema. Adds additional properties 'clocks', 'clock-names', 'power-domains' '#sound-dai-cells', 'num-serializer' and 'port' which were not there in the txt file. Adds 'dmas' and 'dma-names' in the example which were not there in the txt file. Changes 'interrupts' and 'interrupt-names' from optional to required properties.

[PATCH 0/5] xen: cleanup detection of non-essential pv devices
by Juergen Gross 25 Nov '21

25 Nov '21

Today the non-essential pv devices are hard coded in the xenbus driver and this list is lacking multiple entries. This series reworks the detection logic of non-essential devices by adding a flag for that purpose to struct xenbus_driver. Juergen Gross (5): xen: add "not_essential" flag to struct xenbus_driver xen: flag xen_drm_front to be not essential for system boot xen: flag hvc_xen to be not essential for system boot xen: flag pvcalls-front to be not essential for system boot xen: flag xen_snd_front to be not essential for system boot drivers/gpu/drm/xen/xen_drm_front.c | 1 + drivers/input/misc/xen-kbdfront.c | 1 + drivers/tty/hvc/hvc_xen.c | 1 + drivers/video/fbdev/xen-fbfront.c | 1 + drivers/xen/pvcalls-front.c | 1 + drivers/xen/xenbus/xenbus_probe_frontend.c | 14 +++----------- include/xen/xenbus.h | 1 + sound/xen/xen_snd_front.c | 1 + 8 files changed, 10 insertions(+), 11 deletions(-) -- 2.26.2
