nanopi-neo3-plus: add edge (7.1 and prepared 7.2) kernel target support - #10465
nanopi-neo3-plus: add edge (7.1 and prepared 7.2) kernel target support#10465cjkoenig wants to merge 7 commits into
Conversation
Carries NanoPi NEO3 Plus forward to "edge" so it does not lose support once "current" rolls past 6.18. Verified with a full rebuild: rk3528-nanopi-neo3-plus.dtb is present in the resulting linux-dtb-edge-rockchip64 package for BRANCH=edge. "bleedingedge" (rockchip64-7.2, linux-7.2.y) was not added: confirmed that branch isn't reachable through the build tooling yet - forcing KERNEL_MAJOR_MINOR=7.2 gets silently reset back to 7.1 by common_defaults_for_mainline. Nothing to add or verify there until Armbian actually promotes 7.2. KERNEL_TARGET updated from "current" to "current,edge" accordingly.

📝 WalkthroughWalkthroughThe PR updates NanoPi NEO3 Plus board metadata, adds RK3528 Device Tree definitions for Rockchip64 7.1 and 7.2, and moves the Rockchip64 6.18 SPI1 spidev device to chip select 0. ChangesNanoPi NEO3 Plus support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds edge-kernel support for NanoPi NEO3 Plus, but the current version has a Device Tree mapping error that can prevent correct SD-card operation, along with unresolved USB3, regulator-state, and kernel-target DTB concerns. It is not merge-ready until these bounded hardware and configuration risks are fixed or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Would you stand up as a maintainer? BOARD_MAINTAINER="cjkoenig" and we need to tell which auto images to make: KERNEL_TEST_TARGET="current" |
I can step in (best effort) and picked current for auto generation: 1af4257 |

Just a reminder: changes from 7.1 will not be dragged forward to 7.2 at this stage if they aren't present. Meaning when #10448 is merged, your 7.1 dt will be lost. |
…r current and edge spi1 on this RK3528 SPI1 controller has num_chipselect=1: spi1_csn0 and spi1_csn1 are alternate pin routings of the single native chip-select 0, not independent indices. reg=<1> made the kernel reject the device (cs1 >= max 1), so spidev never registered. spi1_csn1 stays selected via pinctrl-0, since it is the pin actually wired out on the header.
…urrent and edge FriendlyElec's spec sheet lists the Type-A host port as USB 3.0, and the combphy on this board is not used for PCIe (no M.2 slot), so wire it up as the USB3 phy instead of leaving it unused, and drop the maximum-speed cap that was artificially limiting the port to USB2.
armbian#10448 bumps the "edge" kernel target to 7.2 and drops the rockchip64-7.1 patchset entirely. Ported ahead of time: rk3528.dtsi renamed the USB2 PHY labels (u2phy* -> usb2phy*) going into 7.2, and usb_host0_xhci now gets its USB2/USB3 phys wired by default at SoC level, so the board override no longer needs to repeat them. All other labels this board dts references are unchanged between 7.1 and 7.2. Verified: compiles cleanly against the real 7.2 kernel tree (BRANCH=bleedingedge, KERNEL_GIT=shallow).

Description
Carries NanoPi NEO3 Plus forward to "edge" so it does not lose support once "current" rolls past 6.18.
KERNEL_TARGET updated from "current" to "current,edge" accordingly.
How Has This Been Tested?
Verified with a full rebuild: rk3528-nanopi-neo3-plus.dtb is present in the resulting linux-dtb-edge-rockchip64 package for BRANCH=edge.
"bleedingedge" (rockchip64-7.2, linux-7.2.y) was not added: confirmed that branch isn't reachable through the build tooling yet - forcing KERNEL_MAJOR_MINOR=7.2 gets silently reset back to 7.1 by common_defaults_for_mainline. Nothing to add or verify there until Armbian actually promotes 7.2.
