[PATCH] ALSA: aoa: Use helper function for_each_child_of_node()
by Zhang Zekun 16 Aug '24

16 Aug '24

for_each_child_of_node can help to iterate through the device_node, and we don't need to use while loop. No functional change with this conversion.

[PATCH v2 0/6] ASoC: codecs: wsa88xx: add support for static port mapping.
by srinivas.kandagatla＠linaro.org 15 Aug '24

15 Aug '24

Existing way of allocating soundwire master ports on Qualcommm platforms is dynamic, and in linear order starting from 1 to MAX_PORTS. This will work as long as soundwire device ports are 1:1 mapped linearly. However on most Qcom SoCs like SM8550, SM8650, x1e80100, these are NOT mapped in that order. The result of this is that only one speaker among the pair of speakers is always silent, With recent changes for WSA codec to support codec versions and along with these patches we are able to get all speakers working on these SoCs.

[PATCH 5.10 031/352] ARM: pxa: spitz: use gpio descriptors for audio

5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd(a)arndb.de> [ Upstream commit 726d8c965bae2d7468445d990849e281dca8cbf7 ] The audio driver should not use a hardwired gpio number from the header.
