Subject: [PATCH] mci: stm32_sdmmc2: add support for SDMMC v2.0 as well
Date: Tue, 20 Oct 2020 18:52:14 +0200	[thread overview]
Message-ID: <20201020165214.2232-1-a.fatoum@pengutronix.de> (raw)

According to kernel commit 7a2a98be672b ("mmc: mmci: Add support for
sdmmc variant revision 2.0")[0], v2.0 is completely backwards compatible
with v1.1. Add the v2.0's periphid to have the driver work with both.
