[ Upstream commit 5d7e328e20b3d2bd3e1e8bea7a868ab8892aeed1 ]
This patch reverts a series of commits that allowed for the ASP registers to be owned by either the driver or the firmware. Nothing currently depends on the functionality that is being reverted, so it is safe to remove.
The commits being reverted are (last 3 are bugfixes to the first 2): commit 72a77d7631c6 ("ASoC: cs35l56: Fix to ensure ASP1 registers match cache") commit 07f7d6e7a124 ("ASoC: cs35l56: Fix for initializing ASP1 mixer registers") commit 4703b014f28b ("ASoC: cs35l56: fix reversed if statement in cs35l56_dspwait_asp1tx_put()") commit c14f09f010cc ("ASoC: cs35l56: Fix deadlock in ASP1 mixer register initialization") commit dfd2ffb37399 ("ASoC: cs35l56: Prevent overwriting firmware ASP config")
These reverts have been squashed into a single commit because there would be no reason to revert only some of them (which would just reintroduce bugs).
The changes introduced by the commits were well-intentioned but somewhat misguided. ACPI does not provide any information about how audio hardware is linked together, so that information has to be hardcoded into drivers. On Windows the firmware is customized to statically setup appropriate configuration of the audio links, and the intent of the commits was to re-use this information if the Linux host drivers aren't taking control of the ASP. This would avoid having to hardcode the ASP config into the machine driver on some systems.
However, this added complexity and race conditions into the driver. It also complicates implementation of new code.
The only case where the ASP is used but the host is not taking ownership is when CS35L56 is used in SoundWire mode with the ASP as a reference audio interconnect. But even in that case it's not necessarily required even if the firmware initialized it. Typically it is used to avoid the host SDCA drivers having to be capable of aggregating capture paths from multiple SoundWire peripherals. But the SOF SoundWire support is capable of doing that aggregation.
Reverting all these commits significantly simplifies the driver. Let's just use the normal Linux mechanisms of the machine driver and ALSA controls to set things up instead of trying to use the firmware to do use-case setup.
