* sunxi: Enable eMMC on Libre Computer Board ALL-H3-CC boardsChen-Yu Tsai2018-07-171-0/+9
| | | | | | | | | | | | | | | | | | | | | | 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.

* sunxi: DT: update device tree files for Allwinner H3 and H5 SoCsAndre Przywara2018-07-161-2/+0
| | | | | | | | | | | | | | | | | | | | | | | Update the device tree files from the Linux tree as of v4.18-rc3, exactly Linux commit: commit 55c5ba5e49a0a124ed416880e8227b493474495e Author: Chen-Yu Tsai <wens@csie.org> Date: Tue Apr 24 19:34:22 2018 +0800 arm64: dts: allwinner: h5: Add cpu0 label for first cpu Since the H3 and H5 are very similar (aside from the actual ARM cores), they share most the SoC .dtsi and thus have to be updated together. One tiny change is the removal of the "arm/" prefix from the include path in the sun50i-h5.dtsi, which is needed because we don't share the same sophisticated DT directory layout of Linux. Also we need to fix up the board .dts files already, since the .dtsi removes some pins, so the .dts can't reference them anymore. This is to maintain bisectability.

* sunxi: Split out common board design for ALL-H3-CC device treeChen-Yu Tsai2018-05-011-0/+168
The Libre Computer Project ALL-H3-CC has three models, all using the same board design, but with different pin compatible SoCs and amount of DRAM. Currently only the H3 1GB DRAM variant is supported. To support the two other variants, first split the original device tree into a common board design part and an SoC specific part. The SoC part only defines which SoC is used and model name, and includes the SoC specific dtsi file and the common design dtsi file. Also fix up the SPDX identifier line to use the correct comment style, and place it on the first line.
