From: Jernej Skrabec <[email protected]> The Orange Pi 3 LTS is an Allwinner H6 board with 2 GiB LPDDR3, 8 GiB eMMC and a Motorcomm YT8531C Gigabit Ethernet PHY. Its Ethernet power, reset and wireless module wiring differ from the Orange Pi 3.
Import the device tree submitted for Linux in the linked patch. Keep it in the local U-Boot DTS directory until the board is available through dts/upstream, and include the current upstream H6 SoC and OPP descriptions. Incorporate the clock naming, supply chaining and BLDO3 always-on fixes requested during Linux review. Describe the PM bank supply and the DCDCA/DCDCB polyphase arrangement. Program both RGMII delays in the PHY with the MAC delays disabled, as proposed during the Ethernet review. Use green PL7 as the power LED and red PL4 as the status LED. Keep the red status LED on during Linux startup and provide a U-Boot-only override that lights green and leaves red off in the bootloader.
