We are starting to see traditional SoC peripherals also in the x86 world,
things like UART, I2C and SPI controllers that might already have a working
device driver. These drivers typically take advantage of the Linux clk
framework to control and retrieve information about the peripheral clock.
There hasn't been a standard way on x86 to pass the clock rate from
whatever configuration system is used to the driver, but instead different
variations have emerged, like adding this information to the platform data.
In order to use the standard Linux way we enable the common clk subsystem
also on x86. This allows us to re-use the drivers with little or no
modification wrt. clock API usage.
This patch was originally proposed by Mark Brown.
