From c3904a2698916305e94eb7fae72e3ea1df9f83b4 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Sun, 4 Jun 2017 10:43:44 +0800 Subject: [PATCH] arm64: allwinner: a64: add DTSI file for SoPine SoM SoPine is a SoM by Pine64, which have a gold finger compatible with the slot of DDR3 SODIMM (signals are not compatible), and have an A64, an AXP803, a LPDDR3 DRAM chip, a power led and a MicroSD slot on it. The card detect pin of the MicroSD slot on the SoM is pulled down, which makes it unusable; however, the slot is at the surface of the SoM that is closed to the baseboard, so it's nearly impossible to hot-swap it, thus I make it non-removable.
