Subject: [PATCH v3 2/2] arm64: dts: allwinner: a64: Add A64 OlinuXino board (with eMMC)
Date: Wed, 21 Aug 2019 12:52:17 -0700	[thread overview]
Message-ID: <20190821195217.4166-3-sunil@medhas.org> (raw)
In-Reply-To: <20190821195217.4166-1-sunil@medhas.org>

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
