Subject: [PATCH 04/10] mmc: sdhci-msm: Add get_min_clock() and get_max_clock() callback
Date: Wed, 10 Aug 2016 20:31:53 +0530 [thread overview]
Message-ID: <1470841319-6091-5-git-send-email-riteshh@codeaurora.org> (raw)
In-Reply-To: <1470841319-6091-1-git-send-email-riteshh@codeaurora.org>
This add get_min_clock() and get_max_clock() callback
for sdhci-msm. sdhci-msm min/max clocks may be different
hence implement these callbacks.
