From 9aa6df9cb82e8fd44132c481afc76eb7a7dbc398 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Wed, 16 Oct 2024 18:23:28 +0800 Subject: ASoC: rt712-sdca: detect the SMART_MIC function during the probe stage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We shouldn't do any devm_ based allocation in the io_init(), this need to happen in the probe(). Luckily, we now have an SDCA helper to look in ACPI tables if a SMART_MIC function is exposed. FIXME: the registers are not well handled today, the regmap lists registers which are not really supported in all platforms. The regmap needs to throw an error if those registers are accessed without existing.
