In TI dra7xx u-boot, PAD_UART3_RXD MUX mode is set as M14(0xe) in board/ti/dra7xx/mux_data.h. But check DRA75X/74X Technical Reference Manual. The CTRL_CORE_PAD_UART3_RXD should set MUX mode as M0(0x0) is right. I wonder u-boot code is work fine. Is DRA75X/74X Technical Reference Manual incorrect? If the manual is not right, where can I get the right SoC manual?
