[PATCH v3 0/2] arm64: dts: allwinner: a64: Add A64 OlinuXino board (with eMMC)

[Sunil Mohan Adapa]

A64 OLinuXino board from Olimex has three variants with onboard eMMC:
A64-OLinuXino-1Ge16GW, A64-OLinuXino-1Ge4GW and A64-OLinuXino-2Ge8G-IND. In
addition, there are two variants without eMMC. One without eMMC and one with SPI
flash. This suggests the need for separate device tree for the three eMMC
variants.

Changes:

  v3: Separate dts for eMMC variants

  v2: Fix descriptions for VCC and VCCQ

Version 2 of this series already committed in linux-sunxi tree as
8d3071f3e85894be35a1b35bcf6fdef970c81018 must be reverted before applying this.

[PATCH v3 1/2] dt-bindings: arm: sunxi: Add compatible for A64 OlinuXino with eMMC

[Sunil Mohan Adapa]

A64 OLinuXino board from Olimex has three variants with onboard eMMC:
A64-OLinuXino-1Ge16GW, A64-OLinuXino-1Ge4GW and A64-OLinuXino-2Ge8G-IND. In
addition, there are two variants without eMMC. One without eMMC and one with SPI
flash. This suggests the need for separate device tree for the three eMMC
variants.

Add new compatible string to the bindings documentation for the A64 OlinuXino
board variant with on-board eMMC.

[PATCH v3 2/2] arm64: dts: allwinner: a64: Add A64 OlinuXino board (with eMMC)

[Sunil Mohan Adapa]

A64 OLinuXino board from Olimex has three variants with onboard eMMC:
A64-OLinuXino-1Ge16GW, A64-OLinuXino-1Ge4GW and A64-OLinuXino-2Ge8G-IND. In
addition, there are two variants without eMMC. One without eMMC and one with SPI
flash. This suggests the need for separate device tree for the three eMMC
variants.

This patch has been tested on A64-OLinuXino-1Ge16GW with Linux 5.0 from Debain.
Basic benchmarks using Flexible IO Tester show reasonable performance from the
eMMC.

eMMC - Random Write: 21.3MiB/s
eMMC - Sequential Write: 68.2MiB/s
SD Card - Random Write: 1690KiB/s
SD Card - Sequential Write: 11.0MiB/s

Changes:

  v3: Separate dts for eMMC variants

  v2: Fix descriptions for VCC and VCCQ
