Well, the problem with adding this to the spi-pl022 driver (as a vendor specific extension) is that this IP block unfortunately isn't distinguishable from the standard ARM PL022 implementation (same values in the PrimeCell identification registers). That's why I went down the GPIO path...
Would it not be more straightforward to just register it as a platform device in this case, or use a separate OF ID in the DT? We appear to specify a compatible string when registering AMBA devices even if we are capable of identifying using the ID registers. -------------- next part -------------- A non-text attachment was scrubbed...
