From c0c5a242bba878b4d34f7c9612fd6cd6c404d414 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Amadeusz=20S=C5=82awi=C5=84ski?= Date: Thu, 7 Jul 2022 14:56:58 +0200 Subject: [PATCH] ASoC: codecs: rt298: Fix jack detection MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On our RVP platforms using rt298 with combojack we've seen issues with controls being in incorrect state after suspend/resume cycle. This is caused by codec driver not setting pins to correct state and causing codec suspend method to not be called. Which on resume caused codec registers to be in undefined state. Fix this by setting pins correctly in jack detect function. Above problem is caused by the fact that when jack == NULL code doesn't reach rt298_jack_detect() function which sets pins. Alternatively problem could be fixed by just moving rt298_jack_detect, but as rt298 codec is similar to rt286, align the code by setting pins explicitly.
