Thu Nov 19 17:05:11 PST 2015
From: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>
Define the SILK board dependent part of the SDHI1 (connected to micro-SD
slot) device nodes along with the necessary voltage regulators.
Based on the original patch by Vladimir Barinov
<vladimir.barinov at cogentembedded.com>.
