[PATCH v3 0/7] ARM: at91: prepare transition to common clk framework

Hello,

This patch series prepares the transition to common clk framework by
1) replacing all the clk_enable and clk_disable calls by clk_prepare_unable and
   clk_disable_unprepare to avoid common clock framework warnings.
2) adding explicit configuration of clk (set_rate) within drivers instead of
   default configuration done in arch/arm/mach-at91/clock.c (udc and ohci
   drivers)

If the second part of this patch series (the last 2 patches) does not belong
here, please tell me and I'll move it into the "move to common clk framework"
series.

Best Regards,
Boris

Changes since v2:
 - add configuraton of usb clock in ohci and udc drivers
 - add clk_prepare patch for usba udc driver
 - add clk_prepare patch for spi driver
 - remove already applied udc clk_prepare patch

Changes since v1:
 - remove unneeded clk_unprepare in mci driver
 - remove already applied patches (ehci, ohci, dma and serial)

Changes since common clk patch series:
 - add clk_prepare_enable return check
 - fix a deadlock in atmel-mci (missing spin_unlock)
 - remove already applied patches (atmel-ssc and pwm-atmel-tcb)
