From 8a68a509ae6b5d7d18c6bfc88553ca7761029ada Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 5 Mar 2019 12:38:59 +0100 Subject: ASoC: rt5651: Add support for active-high jack detect Some boards use a jack-receptacle with a switch which reports the jack-inserted status as active-high, rather then the standard active-low reporting most jacks use. This commit adds support for it. This is activated by a boolean "realtek,jack-detect-not-inverted" device-property. The not-inverted in the device-property name, rather then active-high, was chosen to keep the device-property naming consistent with the rt5640 codec driver.
