The validation is unhappy about mmp3-dell-ariel declaring its marvell,tauros3-cache node to be compatible with arm,pl310-cache: mmp3-dell-ariel.dt.yaml: cache-controller@d0020000: compatible: Additional items are not allowed ('arm,pl310-cache' was unexpected) mmp3-dell-ariel.dt.yaml: cache-controller@d0020000: compatible: ['marvell,tauros3-cache', 'arm,pl310-cache'] is too long Let's allow this -- Tauros 3 is designed to be compatible with PL310.
