Olimex A64-Teres-I board is a mainboard (the only one so far) for Olimex Teres-I DIY laptop kit. Key features: - Allwinner A64 Cortex-A53 - Mali-400MP2 GPU - AXP803 PMIC - 2GB DDR3 RAM - MicroSD Slot - 16GB eMMC Flash - eDP LCD display - HDMI - USB Host - Battery management - 5V DC power supply - Certified Open Source Hardware (OSHW) Works: - i2C - MMC/SD - PWM backlight Known broken: - Internal keyboard (seems to be because the keyboard firmware loads a bootloader first, and then disconnects bootloader and connect real keyboard). External ones connected to the USB port work fine. This patch enables support for the A64-Teres-I board to u-boot, including enabling screen backlight (lacking from Linux device-tree). Linux commit details about the sun50i-a64-teres-i.dts sync: "arm64: dts: allwinner: a64: Rename uart0_pins_a label to uart0_pb_pins" (sha1: d91ebb95b96c8840932dc3a10c9f243712555467) Cosmetic warnings regarding whitespace and placement of SPDX notice for dts file was ignored. config and .dtsi file are adapted from pinebook files.
