Subject: [PATCH 1/2] mci: stm32_sdmmc2: add High-Speed (26 & 52 MHz) support
Date: Wed, 12 Feb 2020 15:14:29 +0100	[thread overview]
Message-ID: <20200212141430.8800-1-a.fatoum@pengutronix.de> (raw)

The SDMMC2 doesn't need any special setup for High-Speed modes, except
for the clock changes. Thus set the cap flags if the max clock would
allow for the higher speed mode.
