[PATCH v6 16/16] ARM: dts: add board specific fixed rate clock nodes for Exynos based platforms

[Thomas Abraham]

The clock frequency of xxti and xusbxti clocks is dependent on the frequency of the
on-board oscillator that is used to generate these clocks. So allow the frequency
of these clocks to be specfied from device tree.
