After verifying the minimal v7.0-rc3+pwm15+pwm-fan+RK806 baseline boots
with display on ampere, extended via bisect-by-addition to include 3
more from linux-rk3588-marfrit's pre-cherry-pick set:
0004 enable speaker output (genbook dts + cm5 dtsi)
0005 USB-C PD charging (genbook dts: FUSB302, vcc5v0_otg)
0006 lid switch + USB3 lane mux (genbook dts: gpio-keys SW_LID, usbdp_phy1)
ampere-minimal-devices branch on git.reauktion.de/marfrit/linux-rk3588-marfrit
@ 7c241f2e2835 = the verified-working state with all 6 patches.
Display continues to work — confirms regression source is in one of
the 12 remaining linux-rk3588-marfrit commits (Shawn Lin pcie3 phy
series, Cristian Ciocaltea clk/dts/dw-dp, Sebastian Reichel hdmirx,
Pedro Alves btrtl, plus the WIP suspend/resume patch 0010).

Adds fleet/ampere.yaml manifest and 3 scope-tagged patches in
patches/board/coolpi-genbook/ for the linux-ampere-fourier kernel.
Baseline: mainline v7.0-rc3. Patch set is the verified-working
minimum after a 2026-05-16 bisect campaign:
0001 pwm15 pinctrl entries (rk3588 SoC dtsi)
0002 pwm-fan + thermal cooling cells (genbook dts)
0003 RK806 system-power-controller (cm5 module dtsi)
NOT included (intentionally):
- misc_patches/genbook/kernel/0010 family — suspend/resume +
wakeup WIP, leave out until Markus closes the thread
- 8 cherry-picks (Shawn Lin pcie3 phy, Cristian Ciocaltea
clk+dw-dp, Sebastian Reichel hdmirx, Pedro Alves) plus the
DTS commits (lid switch, USB-C PD, speaker) — one or more
of these black-screens ampere; offender not yet bisected
The linux-rk3588-marfrit branch tip (f8f3ad9, 18 commits ahead
of v7.0-rc3) produced a display regression on ampere
(connector/dpms/SDDM all positive software-side, panel actually
blank). Decomposing patch 0010 into 5 atomic sub-commits and
reverting all 5 (= test-arch-plus-pcie3 branch on
git.reauktion.de/marfrit/linux-rk3588-marfrit) did NOT fix the
regression, ruling out 0010. The ampere-minimal branch
(v7.0-rc3 + only the 3 patches above) boots clean with display
on ampere — confirming the offender is one of the 14 patches
left out here.
ampere-minimal branch on git.reauktion.de/marfrit/linux-rk3588-marfrit
@ 0ce6ef5d48f2 is the working baseline.
