Subject: [PATCH 3/3] clk: berlin: bg2q: remove non-exist "smemc" gate clock
Date: Wed, 31 Dec 2014 16:57:52 +0800 [thread overview]
Message-ID: <1420016272-6789-4-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1420016272-6789-1-git-send-email-jszhang@marvell.com>
The "smemc" clock is removed on BG2Q SoCs. In fact, bit19 of clkenable
register is for nfc. Current code use bit19 for non-exist "smemc"
incorrectly, this prevents eMMC from working due to the sdhci's
"core" clk is still gated.
