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
