From 8ebc90741e96646af7320336ac4433eea175390a Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Fri, 11 Nov 2022 12:26:47 +0800 Subject: ASoC: SOF: Intel: hda: add per-chip enable_sdw_irq() callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Different generations of Intel hardware rely on different programming sequences to enable SoundWire IP. In existing hardware, the SoundWire interrupt is enabled with a register field in the DSP register space. With HDaudio multi-link extensions registers, the SoundWire interrupt will be enabled with a generic interrupt enable field in LCTL, without any dependency on the DSP being enabled. Add a per-chip callback following the example of the check_sdw_irq() model already upstream. Note that the callback is not populated yet for MeteorLake (MTL) since the interrupts are already enabled in the init. A follow-up patch will move the functionality to this callback after a couple of cleanups.
