Subject: [PATCH 4/4] sdhci: arasan: Remove quirk for broken base clock
Date: Tue, 21 Jan 2020 15:51:35 +0530 [thread overview]
Message-ID: <1579602095-30060-5-git-send-email-manish.narani@xilinx.com> (raw)
In-Reply-To: <1579602095-30060-1-git-send-email-manish.narani@xilinx.com>
This patch removes quirk which indicates a broken base clock. This was
making the kernel report wrong base clock of ~187MHz instead of 200MHz
even as the measurement on the hardware was showing 200MHz.
