Subject: [PATCH 3.12 62/77] clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg clock
Date: Mon, 13 Jan 2014 16:28:23 -0800 [thread overview]
Message-ID: <20140114002754.261397312@linuxfoundation.org> (raw)
In-Reply-To: <20140114002752.497010554@linuxfoundation.org>
3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Abhilash Kesavan <a.kesavan@samsung.com>
commit 2feed5aecf5f367b92bd6b6e92afe9e3de466907 upstream.
The sysreg (system register) generates control signals for various blocks
like disp1blk, i2c, mipi, usb etc. However, it gets disabled as an unused
clock at boot-up. This can lead to failures in operation of above blocks,
because they can not be configured properly if this clock is disabled.
