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.
