Closes the migration started in #8. The 6 active ampere patches (pwm15, pwm-fan, RK806 power-controller, speaker, USB-C PD, lid switch) landed in #8 under soc/rockchip/rk3588/, module/coolpi-cm5/, and board/coolpi-cm5-genbook/. This commit migrates the remaining 3: * `0006 arm64 Kconfig: do not select HAVE_GCC_PLUGINS` → patches/arch/arm64/. NOT for upstream — local build workaround; README explains the proper fix is gcc-plugin-devel install. * `0009 Bluetooth: btrtl: make RTL_SEC_PROJ read non-fatal` → patches/driver/bluetooth/btrtl/. Benefits ampere (RTL8852BE) and boltzmann (same M.2 family). Cross-host driver/ scope. * `0010 gpio/drm/mfd/input/dts: fix suspend/resume and wakeup on RK3588` → SPLIT into 5 scope-tagged sub-patches as the issue required ("0010 split into ≥2 patches by scope"): - patches/driver/gpio/rockchip/0010a-gpio-rockchip-propagate-irq_set_wake-to-parent-GIC.patch - patches/driver/gpu/drm/bridge/analogix/0010b-drm-bridge-analogix-dp-disable-IRQ-before-clock-gating-in-suspend.patch - patches/driver/mfd/rk8xx/0010c-mfd-rk8xx-spi-add-PM-ops-and-shutdown-callback.patch - patches/driver/input/misc/0010d-input-rk805-pwrkey-register-wake-IRQ-via-dev_pm_set_wake_irq.patch - patches/board/coolpi-cm5-genbook/0010e-arm64-dts-rockchip-rk3588-coolpi-cm5-genbook-add-NPU-power-domain-and-touchpad-wakeup.patch The split is byte-identical to the original 0010 (verified on decompose-0010 branch in marfrit/linux-rk3588-marfrit — sha256 of the combined diff matches the monolithic 0010 commit). All 0010 sub-patches marked WIP in their README and explicitly NOT added to fleet/ampere.yaml includes — suspend/resume thread is still open and Markus hasn't decided the upstream-targeting shape. READMEs added at each new directory documenting per-patch context. Acceptance criteria from #1: [x] Each patch lives at narrowest correct scope [x] 0010 split into ≥2 patches by scope (5 sub-patches) [x] Per-host manifest for ampere references the right scopes + explicit includes (already #8) [ ] github.com/marfrit/misc_patches retained as historical mirror — Markus to decide [x] working-tree dirty state on boltzmann reconciled (decompose-0010 + ampere-minimal-devices branches captured) Generated-by: Claude Opus 4.7 <claude@reauktion.de>

Subject: [PATCH 2/9] drm/bridge: analogix-dp: disable IRQ before clock gating
|
|
in suspend
|
|
|
|
analogix_dp_suspend() powers off the PHY and disables the clock but
|
|
leaves the eDP IRQ enabled. During the noirq suspend phase,
|
|
suspend_device_irqs() calls synchronize_irq() which waits for any
|
|
running handler to complete. If the eDP controller fires a spurious
|
|
interrupt after the clock was gated, the hardirq handler accesses
|
|
registers on a dead bus, hanging synchronize_irq().
|
|
|
|
Add disable_irq() before powering down and enable_irq() after
|
|
re-initialization in the resume path. Ensure enable_irq() is called
|
|
even if clk_prepare_enable() fails, to avoid leaving the IRQ
|
|
permanently disabled.
