[Milbeaut PATCH v0.4 1/2] dt-bindings: mmc: sdhci-fujitsu.txt: add miilbeaut driver

From: Takao Orito
Date: Tue Mar 26 2019 - 00:56:19 EST


Add new compatible description for Milbeaut SoC. Socionext
inherits F_SDH30 IP from Fujitsu. Then new Soc series "Milbeaut"
has F_SDH30 controller specified by "socionext,milbeaut-m10v-sdhci-3.0".
