Subject: [PATCH v2] slimbus: qcom-ngd-ctrl: Reduce auto suspend delay
Date: Fri,  8 Mar 2024 18:11:29 +0530
Message-Id: <20240308124129.7833-1-quic_vdadhani@quicinc.com>
Precedence: bulk

Currently we have auto suspend delay of 1s which is
very high and it takes long time to driver for runtime
suspend after use case is done.

Hence to optimize runtime PM ops, reduce auto suspend
delay to 100ms.
