You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From 285880a23d105e5d34b311b0c44061dffb07e405 Mon Sep 17 00:00:00 2001 From: Daniel Baluta <daniel.baluta@nxp.com> Date: Wed, 4 Dec 2019 15:15:53 -0600 Subject: [PATCH] ASoC: SOF: Make creation of machine device from SOF core optional Currently, SOF probes machine drivers by creating a platform device and passing the machine description as private data. This is driven by the ACPI restrictions. Ideally, ACPI tables should contain the description for the machine driver. This is not possible because ACPI tables are frozen and used on multiple OS-es (e.g Windows). In the case of Device Tree we don't have this restriction, so we choose to probe the machine drivers by creating a DT node as is the standard ALSA way. This patch makes the probing of machine drivers from SOF core optional allowing for Device Tree platforms to decouple the SOF core from machine driver probing. Along with this, it also consolidates the machine driver selection for Intel platforms by defining optional ops for selecting the machine driver based on the ACPI match for HDA and non-HDA platforms and setting the mach params.
