Several devices can be attached to memory controllers (or memory-mapped
buses), thus they can come with additional controller-specific
properties, e.g. devices wired under Intel IXP4XX bus: cfi-flash,
intel,ixp4xx-compact-flash, NS8250 serial and MAX6369 watchdog.
Referencing Memory Controller or IXP4XX bus peripheral properties fixes
few dtbs_check warnings like:
intel-ixp42x-gateworks-gw2348.dtb: ide@1,0: Unevaluated properties are not allowed
('intel,ixp4xx-eb-ahb-split-transfers', 'intel,ixp4xx-eb-byte-access', ... ' were unexpected)
