Subject: [PATCH 2/2] mmc: mmc_spi: enable Highspeed for above 25MHz
Date: Thu, 31 Mar 2022 07:29:37 +0000	[thread overview]
Message-ID: <5eaae8e215d84dd3a4f7e09782478a29@hyperstone.com> (raw)
In-Reply-To: <20c6efa9a4c7423bbfb9352705c4a53a@hyperstone.com>

Any setup supporting more than 25MHz is able to utilize
highspeed, so enable it even when not explicitly specified.
