Subject: [PATCH v2 13/20] ARM: k3: limit eMMC frequency to 26MHz
X-SA-Exim-Version: 4.2.1 (built Wed, 08 May 2019 21:11:16 +0000)
X-SA-Exim-Scanned: Yes (on metis.whiteo.stw.pengutronix.de)
The eMMCs on am625 currently only work reliably with 26MHz. Until this
issue is sorted out limit them to 26MHz on the affected boards
(beagleplay and am625-sk).
