Hi,
ARMv8's generic timer[1] picks up it's graycode from GTC. However, the frequency of the GTC is supposed to be programmed in CNTFID0[2] register prior to enabling the GTC in CNTCR[3] register. U-boot for K3 is currently missing that programming sequence. This series introduces the clock nodes necessary for the lookup and writes the frequency to the corresponding register for TF-A to pick up [4].

Applied to u-boot-ti/for-next branch.
Thanks and regards, Lokesh
