From 9d062b9b416857873bb149e18fbb4230d202d0e8 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 29 May 2015 11:38:44 -0500 Subject: [PATCH] dt-bindings: Consolidate ChipIdea USB ci13xxx bindings Combine the ChipIdea USB binding into a single document to reduce duplication and fragmentation. This marks use of the old PHY bindings as deprecated. Future compatible bindings should use generic PHY binding. Signed-off-by: Rob Herring Cc: Ivan T.
