From 32f67bb7a15cec4afa117bd168265ece2107b0d6 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Sat, 14 Jul 2018 21:55:45 +0800 Subject: sunxi: Enable eMMC on Libre Computer Board ALL-H3-CC boards The Libretech ALL-H3-CC has a high density connector for attaching an eMMC module. The module form factor and connection is specific to Libretech, and has provisions for split vmmc/vqmmc (core and I/O) voltage supplies, but this board does not wire the vqmmc side. The H2+/H3/H5 SoCs do not support alternate I/O voltages for eMMC either. Only 3.3V is supported. A specific module that ties vqmmc to vmmc, with both at 3.3V, must be used. Given that a) eMMC is not designed to be hotplugged, b) power is always provided on the pins, and c) MMC controllers can deal with missing cards, we can enable this by default. If a module is attached it will be picked up by the system. The device tree change was also submitted to the Linux Kernel and has already been queued up for 4.19.
