From 732c678eb021dbc514a699be1815e194692fdd5c Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Tue, 21 Nov 2023 15:44:19 +0000 Subject: [PATCH] ALSA: hda: cs35l56: Enable low-power hibernation mode on SPI SPI hibernation is now supported with the latest hibernation/wake sequences in the shared ASoC code. This has a functional dependency on two commits: commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice") commit a47cf4dac7dc ("ASoC: cs35l56: Change hibernate sequence to use allow auto hibernate") To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.
