From 8d66a16dfd6b5c7e0d39e90954af32667e480074 Mon Sep 17 00:00:00 2001
From: Ahmad Fatoum <a.fatoum@pengutronix.de>
Date: Tue, 6 Sep 2022 20:10:37 +0200
Subject: [PATCH 2/3] mci: core: add broken_cd device parameter
Sometimes a broken card-detect is not a general issue affecting all
boards, but only a given board. Allow setting broken_cd for such boards
via a device parameter.
