Subject: [PATCH v2 3/5] ASoC: rt711-sdca: fix for JD event handling in ClockStop Mode0
Date: Fri, 21 Jul 2023 17:07:11 +0800	[thread overview]
Message-ID: <20230721090711.128247-1-shumingf@realtek.com> (raw)

From: Shuming Fan <shumingf@realtek.com>

When the system suspends, peripheral SDCA interrupts are disabled.
When system level resume is invoked, the peripheral SDCA interrupts
should be enabled to handle JD events.
Enable SDCA interrupts in resume sequence when ClockStop Mode0 is applied.
