From 0342518b0c15481dd4359b499301711b2f9a796c Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Tue, 12 Sep 2023 14:27:39 +0100 Subject: [PATCH] ALSA: hda: cs35l56: Disable low-power hibernation mode Do not allow the CS35L56 to be put into its lowest power "hibernation" mode. This only affects I2C because "hibernation" is already disabled on SPI. Recent firmwares need a different wake-up sequence. Until that sequence has been specified, the chip "hibernation" mode must be disabled otherwise it can intermittently fail to wake.
