Subject: [PATCH v1 4/4] arm64: dts: imx8mq-librem5: Reduce usdhc2's post-power-on-delay-ms to 20ms
Date: Mon, 17 Jul 2023 10:00:56 +0000 [thread overview]
Message-ID: <20230717100056.4047292-5-martink@posteo.de> (raw)
In-Reply-To: <20230717100056.4047292-1-martink@posteo.de>
From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@puri.sm>

Waiting for too long makes us waste time in resume from system
