In addition to the regular mux configuration, certain pins of DRA7 require to have "manual mode" also programmed, when predefined delay characteristics cannot be used for the interface. struct iodelay_cfg_entry is introduced for populating manual mode IO timings. For configuring manual mode, along with the normal pad configuration do the following steps: - Select MODESELECT field of each assocaited PAD. CTRL_CORE_PAD_XXX[8]:MODESELECT = 1(Enable MANUAL_MODE macro along with mux) - Populate A_DELAY, G_DELAY values that are specified in DATA MANUAL. And pass the offset of the CFG_XXX register in iodelay_cfg_entry. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> |
