[PATCH v3 1/2] ASoC: dt-bindings: sound-card-common: List DAPM endpoints ignoring system suspend
by Chancel Liu 16 Oct '23

16 Oct '23

Add a property to list DAPM endpoints which mark paths between these endpoints should not be disabled when system enters in suspend state. LPA means low power audio case. For example on asymmetric multiprocessor, there are Cortex-A core and Cortex-M core, Linux is running on Cortex-A core, RTOS or other OS is running on Cortex-M core. The audio hardware devices can be controlled by Cortex-M. LPA can be explained as a mechanism that Cortex-A allocates a large buffer and fill audio data, then Cortex-A can enter into suspend for the purpose of power saving. Cortex-M continues to play the sound during suspend phase of Cortex-A. LPA requires some audio paths still enabled when Cortex-A enters into suspend.

[PATCH] soundwire: bus: improve error handling for clock stop prepare/deprepare
by Bard Liao 16 Oct '23

16 Oct '23

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> The same logic is used for clock stop prepare and deprepare, and having different logs for the two steps helps identify problems. In addition, when the "NotFinished" bit remains set, the error handling is not quite right: a) for the clock stop prepare, the error is handled at the caller level, and the error is ignored: there's no good reason to prevent the pm_runtime suspend from happening. Throwing an error that is later ignored is confusing. b) for the clock stop deprepare, the error is ignored in bus.c and a dev_warn() log shown. Throwing an error is also alarming users for no good reason. For both cases, demoting the error to dev_dbg() makes more sense.

[PATCH v4 00/42] ep93xx device tree conversion
by Nikita Shubin via B4 Relay 16 Oct '23

16 Oct '23

This series aims to convert ep93xx from platform to full device tree support. The main goal is to receive ACK's to take it via Arnd's arm-soc branch. Major changes: - drop newline at the end from each YAML files - rename dma and clk bindings headers to match first compatible - shrink SoC exported functions number to only 2 - dropped some ep93xx_pata fixes from these series - dropped m48t86 stuff from these series Bit thanks to Andy Shevchenko for thorough review. Some parts are were sent in advance, so these series depends on the following: Link: https://lore.kernel.org/all/20230823-m48t86_device_tree-v2-0-21ff275f949d@m… Link: https://lore.kernel.org/all/20230823-ep93xx_pata_fixes-v1-0-d7e7229be148@ma… --- Changes in v4: -
