[PATCH] ASoC: dt-bindings: renesas, rsnd: Group tuples in playback/capture properties
by Geert Uytterhoeven 05 Feb '21

05 Feb '21

To improve human readability and enable automatic validation, the tuples in "playback" and "capture" properties in sound device nodes should be grouped using angle brackets.

[RESEND PATH] ASoC: dmaengine_pcm: add peripheral configuration
by Shengjiu Wang 05 Feb '21

05 Feb '21

The commit e7bbb7acabf4 ("dmaengine: add peripheral configuration") adds peripheral configuration for dma_slave_config. This configuration is useful for some audio peripherals, for example, the peripheral supports multi fifos, we can let the DMA know which fifos are selected. So also add this configuration for snd_dmaengine_dai_dma_data.

[PATCH] ALSA: usb-audio: Fix PCM buffer allocation in non-vmalloc mode
by Takashi Iwai 05 Feb '21

05 Feb '21

The commit f274baa49be6 ("ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffers") introduced the mode to allocate coherent pages for PCM buffers, and it used bus->controller device as its DMA device. It turned out, however, that bus->sysdev is a more appropriate device to be used for DMA mapping in HCD code. This patch corrects the device reference accordingly. Note that, on most platforms, both point to the very same device, hence this patch doesn't change anything practically. But on platforms like xhcd-plat hcd, the change becomes effective.

[PATCH] coresight: etm4x: Fix merge resolution for amba rework
by Uwe Kleine-König 05 Feb '21

05 Feb '21

This was non-trivial to get right because commits c23bc382ef0e ("coresight: etm4x: Refactor probing routine") and 5214b563588e ("coresight: etm4x: Add support for sysreg only devices") changed the code flow considerably. With this change the driver can be built again.

Sure, here it comes. As I'm unsure if you want to squash it into the merge or want to keep it separate I crafted a commit message. If you prefer squashing feel free to do so. This change corresponds to the merge resolution I suggested before.

[PATCH v3 0/5] amba: minor fix and various cleanups
by Uwe Kleine-König 05 Feb '21

05 Feb '21

From: Uwe Kleine-König <u.kleine-koenig.org(a)pengutronix.de Hello, Changes since v2 sent with Message-Id: 20201124133139.3072124-1-uwe(a)kleine-koenig.org: - Rebase to v5.11-rc1 (which resulted in a few conflicts in drivers/hwtracing). - Add various Acks. - Send to more maintainers directly (which I think is one of the reasons why there are so few Acks). For my taste patch 4 needs some more acks (drivers/char/hw_random, drivers/dma, drivers/gpu/drm/pl111, drivers/i2c, drivers/mmc, drivers/vfio, drivers/watchdog and sound/arm have no maintainer feedback yet). My suggestion is to let this series go in via Russell King (who cares for amba). Once enough Acks are there I can also provide a tag for merging into different trees. Just tell me if you prefer this solution. Would be great if this could make it for v5.12, but I'm aware it's already late in the v5.11 cycle so it might have to wait for v5.13.
