Subject: [PATCH v4 0/5] Add initial Milk-V Duo S board support
Date: Sat, 28 Mar 2026 13:34:45 -0400 [thread overview]
Message-ID: <20260328173450.219664-1-josh.milas@gmail.com> (raw)
This adds an initial device tree for the Milk-V Duo S board
with support for reading from the SD card and network over
Ethernet. This is continued work from Michael Opdenacker's
v6 series [1] on the ARM64 and RISCV side. It has been tested
with ARM64 and RISCV64 to boot from an SD card, have networking,
and read I2C slave devices over i2c4.
---
v4
- Rebased to latest sophogo/for-next
- Added usb node to arm64 and riscv DTS
- Removed sg200x link in commit messages
- Added missing change to v3 and removed link from v2
v3: https://lore.kernel.org/sophgo/20251029001052.36774-1-josh.milas@gmail.com/
- Added sg2000 interrupt controller and timer to documentation
- Added sg2000.dtsi for RISCV and moved DTS over to use it
- remove devices from DTS's to match what is available in the
default pinmux config. spi0-2, i2c0-3, uart1-4
- Added i2c4 and spi3 aliases
- Removed milkv,duo-s from sophgo,cv1812h in documentation
v2: https://lore.kernel.org/sophgo/20251011014811.28521-1-josh.milas@gmail.com/
- Made new entry in docs to avoid DTC error
- "Milk-V DuoS" -> "Milk-V Duo S"
- Sorting of aliases
- Added uart*, emmc, mdio, gmac0, i2c*, spi*, dmac, saradc
to device tree matching what is available on the pinout
- Removal of 'no-mmc' and 'no-sdio' for sdhci0 as it works without
- Added riscv device tree
v1: https://lore.kernel.org/sophgo/20250927173619.89768-1-josh.milas@gmail.com/
