read

of_get_ddr_timings() - extracts the ddr timings and updates no of frequencies available. : Pointer to ddr device tree node : Device requesting for ddr timings : Type of ddr(LPDDR2 S2/S4) : No of frequencies available for ddr (updated by this function)

Populates lpddr2_timings structure by extracting data from device tree node. Returns pointer to populated structure. If any error while populating, returns default timings provided by JEDEC.
