Brings the second customized fleet host into kernel-agent's scope-tagged tree. Sibling PR coming in marfrit-packages with the arch/linux-ampere-fourier/ PKGBUILD + flat patch + config + extlinux hook (build-tree-ready form). Issue #6 ask #1 only — VP9 enablement (ask #2) and AV1 dec integration (ask #3) are explicitly deferred to a separate session per the user's direction. The ampere.yaml manifest documents what's excluded and why. ## Patches promoted Six patches from boltzmann:~/src/misc_patches/genbook/kernel/ get scope-tagged into kernel-agent's tree: soc/rockchip/rk3588/ 0001-...Add-pwm15-pinctrl-entries.patch (prereq for 0002) module/coolpi-cm5/ 0003-...Fix-power-off-by-enabling-RK806-as-system-power-controller.patch board/coolpi-cm5-genbook/ 0002-...Add-pwm-fan.patch 0004-...Enable-speaker-output-via-audio-graph-card.patch 0005-...Enable-USB-C-PD-charging-via-FUSB302.patch 0008-...Add-lid-switch-and-USB3-PHY-lane-config.patch Each new scope dir gets a README.md documenting what it carries and why the scope-level granularity makes sense (pwm15 is SoC-wide, RK806 power-off is SoM-level not board-level, the rest are board-specific GenBook quirks). Note on uncommitted-modifications flag in issue body: patches 0001-0004 have working-tree-only changes in misc_patches that fix malformed 'From: PATCH 000X/000Y' headers (placeholder text instead of an RFC-2822 author identity). The working-tree versions with proper 'From: Markus Fritsche <mfritsche@localhost>' headers are what we ship here — the unfixed-on-disk variants would fail patch -i header parsing on stricter implementations and are user-side cleanup that hasn't been committed back to misc_patches yet. Markus can commit the cleanup to that personal repo separately; this PR's ingestion does not depend on it. Patches 0006 (HAVE_GCC_PLUGINS Kconfig), 0009 (Bluetooth btrtl), 0010 (multi-driver suspend/wakeup) from the misc_patches series are intentionally NOT promoted here — they need different scope tags (arch/arm64/, driver/bluetooth/, soc/rockchip/rk3588/ + driver/ split) and will follow when their respective campaigns demand them. The ampere.yaml manifest documents the explicit-defer for each. ## fleet/ampere.yaml manifest Same shape as fleet/fresnel.yaml. Baseline pinned at marfrit/linux-rockchip branch linux-rk3588-marfrit @ f8f3ad934433 (the working tree on boltzmann; 18 commits ahead of v7.0-rc3, current 2026-05-15 tip). Six scope-tagged patch includes per the apply-order in the package (pwm15 pinctrl must precede the pwm-fan node consumer). ## ampere-specific bootloader path Documented in manifest. ampere boots from /boot/firmware/ (vfat partition on mmcblk0p1), not /boot/ (root partition) like fresnel. The marfrit-packages PKGBUILD's extlinux-add hook needs to write to /boot/firmware/extlinux/extlinux.conf, not /boot/extlinux/. ## ampere as 2nd aarch64 build host Per the README update in PR #7, ampere is now a secondary aarch64 build host. The manifest's build_host: section pins ampere as self-hosting primary for its own kernel, with boltzmann as secondary and fermi as fallback. This is the first manifest that has its own host listed as the primary build target — not ideologically pretty, but pragmatic: native arch, same uarch, full RAM, no cross-compile step, no need to wake another host.

Subject: [PATCH] arm64: dts: rockchip: rk3588-coolpi-cm5-genbook: add lid switch and USB3 PHY lane config
|
|
|
|
The GenBook laptop has two features missing from the mainline DTS:
|
|
|
|
1. Lid switch (MH248 hall-effect sensor on GPIO0_PB0)
|
|
The lid state is reported via a gpio-keys node using SW_LID / EV_SW.
|
|
The GPIO is active-low (low = lid closed) and pulled up.
|
|
wakeup-source is set so that opening the lid can wake the system from
|
|
suspend. A sensor pinctrl group is added for the GPIO configuration.
|
|
|
|
2. usbdp_phy1 lane mux (rockchip,dp-lane-mux = <2 3>)
|
|
The RK3588 usbdp_phy1 is a combo USB3 + DisplayPort PHY shared between
|
|
the USB3 host1 port (USB-A connector) and the DisplayPort output on the
|
|
GenBook board. Lanes 0+1 carry USB3 SuperSpeed to the USB-A socket;
|
|
lanes 2+3 are routed to the DP connector.
|
|
|
|
Without this property the phy-rockchip-usbdp driver selects
|
|
UDPHY_MODE_USB and configures all four lanes as USB3. That conflicts
|
|
with the physical routing on this board: lanes 2+3 are not connected to
|
|
the USB-A socket, so the 4-lane USB3 training fails silently and the
|
|
USB3 host1 DWC3 controller (usb_host1_xhci) cannot enumerate devices.
|
|
|
|
Setting rockchip,dp-lane-mux = <2 3> restricts USB3 to lanes 0+1,
|
|
matching the physical wiring, and enables correct SuperSpeed operation
|
|
on the USB-A port.
|
|
|
|
The USB2 EHCI host1 controller (usb_host1_ehci) shares the USB power
|
|
domain with usb_host1_xhci. A stalled USB3 DWC3 probe can delay
|
|
power-domain activation in a way that prevents the EHCI hub (which
|
|
carries the integrated webcam) from being enumerated. With the correct
|
|
lane mux both controllers probe cleanly and the webcam is detected.
