The 8250_hisi_lpc.c support both ACPI and dts similar to 8250_dw : +static struct platform_driver hs_lpc8250_driver = { + .driver = { + .name = "hisi-lpc-uart", + .of_match_table = hs8250_of_match, + .acpi_match_table = ACPI_PTR(hs8250_acpi_match), So, I am a little confused why we need to support dts in 8250_of.c and support ACPI in another driver file. best, Zhichang > > Arnd > > > . > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
