There is a requirement for supporting an 8250-compatible UART with the following profile/features: - platform device - polling mode (i.e. no interrupt support) - ACPI FW - IO port iotype - 16550-compatible
For OF, we have 8250_of.c, and for PNP device we have 8250_pnp.c drivers. However there does not seem to any driver satisfying the above requirements. So this RFC is to find opinion on modifying the Synopsys DW 8250_dw.c driver to support these generic features.
With patch 2/2, we're relaxing the interrupt support requirement. As I mentioned in the commit log, the 8250_of.c driver seems to ignore the dt bindings, and I do the same.
