I'm trying to use the ns16550 DM driver in a platform where havind a dtb in SPL is not plausible, so we're using platdata.
Now for ns16550 The U_BOOT_DRIVER is guarded by !OF_PLATDATA, so the driver is not compiled in SPL. This seems inconsistent with other U_BOOT_DRIVERs. This was introduced in the following commit [1]:
* b2927fb dm: serial: ns16550: Update to support of-platdata
The reasoning was that the platdata structure is unknown, but one would have to provide a 'struct ns16550_platdata' when using platdata, and that is the case with the boards that use this driver with platdata.
Is this a misguided change, or am I missing something deeper? I can prepare a patch to resolve this, if this is the consensus.
