Merge tag 'clk' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
clock management changes for i.MX
Another simple series related to clock management, this time only for
imx.
* tag 'clk' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
ARM: mxs: select HAVE_CLK_PREPARE for clock
clk: add config option HAVE_CLK_PREPARE into Kconfig
ASoC: mxs-saif: convert to clk_prepare/clk_unprepare
video: mxsfb: convert to clk_prepare/clk_unprepare
serial: mxs-auart: convert to clk_prepare/clk_unprepare
net: flexcan: convert to clk_prepare/clk_unprepare
mtd: gpmi-lib: convert to clk_prepare/clk_unprepare
mmc: mxs-mmc: convert to clk_prepare/clk_unprepare
dma: mxs-dma: convert to clk_prepare/clk_unprepare
net: fec: add clk_prepare/clk_unprepare
ARM: mxs: convert platform code to clk_prepare/clk_unprepare
clk: add helper functions clk_prepare_enable and clk_disable_unprepare
Fix up trivial conflicts in drivers/net/ethernet/freescale/fec.c due to
commit 0ebafefcaa7a ("net: fec: add clk_prepare/clk_unprepare") clashing
trivially with commit e163cc97f9ac ("net/fec: fix the .remove code").
