Subject[PATCH 5.1 003/121] mmc: sdhi: disallow HS400 for M3-W ES1.2, RZ/G2M, and V3H
Date
From: Wolfram Sang <wsa+renesas@sang-engineering.com>

commit 97bf85b6ec9e6597ce81c79b26a28f7918fc4eaf upstream.

Our HW engineers informed us that HS400 is not working on these SoC
revisions.

Fixes: 0f4e2054c971 ("mmc: renesas_sdhi: disable HS400 on H3 ES1.x and M3-W ES1.[012]")
