Subject: [PATCH] ARM: mxs_defconfig: Remove locking debug config options
Date: Thu, 26 May 2011 14:26:43 +0800 [thread overview]
Message-ID: <1306391203-29338-1-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <20110525141624.GE2408@S2100-06.ap.freescale.net>
The amba-pl011 driver assumes that clk_enable/disable are atomic, but
currently it's not the case on mxs. There are lock debug warnings
seen when serial console does power management.
The patch removes locking debug config options to get rid of the
warnings. They can be turned on later when new clock framework sorts
the locking thing out.
