alsa-project/alsa-ucm-conf pull request #243 was opened from craftyguy: This reverts commit 998849d9510754960d808e20dad4c440adaf87ef. The oem (Purism) is working on some big improvements to this config, which I knew of when I submitted the patch this reverts, however I didn't realize until now that their changes would break config. It's probably best to just revert this so it doesn't make it into a release and wait for the oem to submit their improved ucm upstream.

[PATCH v2 0/4] Minor SoundWire clean ups
by Charles Keepax 17 Nov '22

17 Nov '22

Just some minor tidy ups and preparation for starting to upstream some Cirrus SoundWire devices. The first three patches are pretty trivial, the last patch which moves the remaining core over to using the no_pm functions could probably use some careful review. Changes since v1: - Update commit message on the debugfs to more explicitly mention the PM runtime reference, rather than implying the PM would turn on/off each time. - Added some reviewed by's Thanks, Charles Charles Keepax (3): soundwire: Provide build stubs for common functions soundwire: debugfs: Switch to sdw_read_no_pm soundwire: stream: Move remaining register accesses over to no_pm Simon Trimmer (1): soundwire: bus: export sdw_nwrite_no_pm and sdw_nread_no_pm functions drivers/soundwire/bus.c | 10 ++-- drivers/soundwire/debugfs.c | 11 +++- drivers/soundwire/stream.c | 30 +++++------ include/linux/soundwire/sdw.h | 94 +++++++++++++++++++++++++++++++---- 4 files changed, 114 insertions(+), 31 deletions(-) -- 2.30.2
