- For 6.18 + 6.19
- mixtile-blade3: add 4-pin header fan at 40c
- mixtile-blade3: add gpu nodes
- mixtile-blade3: add vcc5v0-host-en "usb" pinctrl
- somehow results in 2 working RTL8169's behind the ASM1182e on pcie2x1l0
- which just means the _schematics lie_
- mixtile-blade3: drop rst pinctrl from pcie2x1l0 and pcie2x1l1
- this is me probably being stupid, but also required for working ASM1182e/RTL8169
- Status of this mainline port:
- Initially started by Joshua Riek (2023?)
- I then added some PCIe3x4 stuff, but never got around to finishing it
- Specifically, the 2 FUSB302's are beyond me for now
- One of them _powers_ the board. To use with mainline, power the board some other way with 12V, otherwise kaboom.
- See sre's talk on this issue; Blade3 should be similar to Rock-5b in this aspect.
- A challenge has been the PCI2x1 lanes to the miniPCIe and ASM1182e switch
- Which by themselves seem to work, but the devices behind them (Switch + RTL8169 NICs) do not get powered
- Until one day I tried to describe a (in theory) USB-related power pin, and suddenly both PCIe NICs started working!
- All that said, the board is really not stable with this; end-users are much better off with vendor kernel for now.
- Any and all help is appreciated. Those boards are nice, they've 2 FUSB302, and fancy PCIe Endpoint mode stuff.
- Schematics we have access to are in https://damwold5pt25n.cloudfront.net/blade3/file/Schematic_Blade_3_v1.1.0.pdf
- Those clearly lie.
- Add mainline device tree for YY3588 board
- Enable all peripherals: USB 3.0, Ethernet, PCIe, HDMI
- Add RK8602 PMIC regulators for CPU/NPU power
- Enable I2C buses for PMIC and RTC
- Fix pinctrl conflicts (I2C1 M2, disable SFC for UART7)
- Configure USB-C and USB 3.0 host ports
- Add HDMI0 output with HDPTX PHY
- Enable thermal management with PWM fan
- Add SD card and eMMC storage support
- Configure all UARTs, I2S audio, and SPI buses
- ES8323 audio codec currently disabled for further debugging
- vendor:
- kernel: armbian/linux-rockchip already had a DTS from jriek
- u-boot: taken from jriek (reorg'ed the defconfig)
- edge:
- kernel: taken from jriek's 6.11 wip branch
- u-boot: generic (can only boot SD/eMMC)
- straight-ish from vendor (which is a complete mess)
- front:
- blue ports work (in usb2.0 mode, which also happens in vendor kernel)
- black ports do NOT work (but are powered...?)
- back:
- white ports work in usb 2.0 mode (as expected, also in vendor kernel)
- those ports have too-long wires (flat cable) and reset all the time
- in summary: blue "USB3" ports at the front work in USB2.0 mode
- rest doesn't
- works: PCIe/NVMe, GMAC, Realtek DSA switch, SD, SPI-NOR
- does not work: USB (I didn't manage to pick correctly; lets wait for Kwiboo on this)
- untested: everything else
- Add mainline U-Boot support for edge branch (v2026.01-rc2)
- Add U-Boot defconfig patch for nanopi-r76s
- Fix USB3.0 Type-A host port configuration in DTS
- Enable USB OTG0 controller in host mode with power GPIO control
- Set KERNEL_TEST_TARGET to edge
- Change debug console from ttyS2 to ttyS0
- Remove SERIALCON from board configs
- Set console based on BOOT_SOC
- Enable UART0 in device tree for nanopi-r76s
