From dcf4694f200a67784e053eb5d1d70a191761ff4f Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Wed, 16 Oct 2024 18:23:29 +0800 Subject: [PATCH] ASoC: soc-acpi: introduce new 'machine check' callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The existing machine_quirk() returns a pointer to a soc_acpi_mach structure. For SoundWire/SDCA support, we need a slightly different functionality where a quirk function either validates or NACKs an initial selection, based on additional firmware/DMI information.
