Subject: [PATCH v1 09/14] arm64: dts: imx8mq-librem5: Bump usdhc2 frequency to 100MHz
Date: Thu, 9 Mar 2023 21:46:03 +0100 [thread overview]
Message-ID: <20230309204608.237605-10-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20230309204608.237605-1-martin.kepplinger@puri.sm>
From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@puri.sm>
RS9116 card already limits itself to 50MHz by being a high-speed card,
while AP6275S can work at 100MHz just fine (technically it should work
at 200MHz as well since it's a SDR104 card, but it doesn't appear to be
the case in practice and further research will be needed to find out why).
