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. Signed-off-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
