[PATCH 6.5] ASoC: cs35l56: Call pm_runtime_dont_use_autosuspend()
by Richard Fitzgerald 03 Oct '23

03 Oct '23

commit ec03804552e9a723569e14d2512f36a8e70dc640 upstream Driver remove() must call pm_runtime_dont_use_autosuspend(). Drivers that call pm_runtime_use_autosuspend() must disable it in driver remove(). Unfortunately until recently this was only mentioned in 1 line in a 900+ line document so most people hadn't noticed this. It has only recently been added to the kerneldoc of pm_runtime_use_autosuspend(). Backport note: This is the same change as the upstream commit but the cs35l56->base.dev argument in the upstream code is cs35l56->dev in older releases.

[PATCH v2 2/2] ASoC: Adds support for TAS575x to the pcm512x driver
by Joerg Schambacher 03 Oct '23

03 Oct '23

Enables the existing pcm512x driver to control the almost compatible TAS5754 and -76 amplifers. Both amplifiers support only an I2C interface and the internal PLL must be always on to provide necessary clocks to the amplifier section.

[PATCH v2 1/2] ASoC: pcm512x: Adds bindings for TAS575x devices
by Joerg Schambacher 03 Oct '23

03 Oct '23

The TAS5754/6 power amplifiers use the same pcm512x driver with only minor restictions described in the bindings document.
