With this code only 19.2 HMz SYSCLK (input) frequency is supported on dra7xx based SoCs.
This wold be breaking dra74x-evm which has 20MHz sysclk. May I know what is intention for configuring PCIE dpll in u-boot?(you want to use PCIE at u-boot or for kernel to depend on this configuration?)
Thanks and regards, Lokesh
