Merge branch 'clk/mxs' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/clock
Shawn Guo <shawn.guo@linaro.org> writes: mxs common clk porting for v3.5. It depends on the following two branches. [1] git://git.linaro.org/people/mturquette/linux.git clk-next [2] http://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-arm.git clkdev As the mxs device tree conversion will constantly touch clock files, to save the conflicts, the updated mxs/dt branch coming later will based on this pull-request. * 'clk/mxs' of git://git.linaro.org/people/shawnguo/linux-2.6: ARM: mxs: remove now unused timer_clk argument from mxs_timer_init ARM: mxs: remove old clock support ARM: mxs: switch to common clk framework ARM: mxs: change the lookup name for fec phy clock ARM: mxs: request clock for timer clk: mxs: add clock support for imx28 clk: mxs: add clock support for imx23 clk: mxs: add mxs specific clocks Includes an update to Linux 3.4-rc6 Conflicts: drivers/clk/Makefile Signed-off-by: Arnd Bergmann <arnd@arndb.de>
