| H A D | uart_dev_mtk.c | 297669 Thu Apr 07 11:21:54 MDT 2016 sgalabov Initial import of Ralink/Mediatek MIPS SoC support #4 UART drivers. - uart_dev_mtk.[ch] are the old-style Mediatek/Ralink-specific UART driver as also found in sys/mips/rt305x/uart_dev_rt305x.c, with minor improvements and FDT attachment enabled for the appropriate SoCs. - uart_dev_mtk_ns8250.c is the new-style ns16550a-compatible UART driver found in newer Mediatek SoCs. It uses the uart_dev_ns8250.c driver indirectly and is basically just a wrapper around it and only overrides its probe method. The reason I am not using the uart_dev_ns8250.c driver directly is because I have some code that does UART clock detection before initializing the UART, so that we don't need to hard-code the UART clock frequency in the dts files for each board.
