From 5b311c1519c658bf06f7a08a2ddc2648e4c9cd5c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 14 Dec 2016 11:10:46 +0900 Subject: [PATCH] mmc: sdhci-cadence: add Socionext UniPhier specific compatible string Add a Socionext SoC specific compatible (suggested by Rob Herring). No SoC specific data are associated with the compatible strings for now, but other SoC vendors may use this IP and want to differentiate IP variants in the future.
