Subject: [PATCH 5/7] Input: mtk-pmic-keys: add field to store if PMIC has key release IRQs
Date:   Fri, 15 Apr 2022 17:36:27 +0200

The MT6358 PMIC is not the only PMIC to have release IRQs. In order to
support more PMIC that supports release IRQs, such as MT6357, MT6359,
and possibly others, let's add some field in the platform data to
indicate whether a PMIC support release keys.
