(Patches are rebased on 2.6.30-rc6. The older version was based on 2.6.30-rc2)
This patch update the common clock.c file for OMAP4. The clk_get() and
clk_put() sunctions are moved to common place in arch/arm/common/clkdev.c
Since on current OMAP4 platform clk management is still not supported, the
platform file is stubbed with those functions.
Once the framework is ready, this WILL be replaced with a full
clkdev implementation.
