patches: migrate remaining misc_patches/genbook into scope-tagged tree (closes #1)

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] arm64: Kconfig: do not select HAVE_GCC_PLUGINS
+
+GCC plugins intercept compilation in a way that ccache cannot observe:
+the plugin shared objects inject code after preprocessing, so the
+preprocessed-source hash that ccache computes does not capture plugin
+output.  Every object file built with a plugin is therefore a ccache
+miss, effectively disabling the cache.
+
+Remove the `select HAVE_GCC_PLUGINS` line from the ARM64 arch Kconfig.
+HAVE_GCC_PLUGINS is the only gate that allows GCC_PLUGINS (and the
+features that depend on it: STACKLEAK, LATENT_ENTROPY, the GCC-based
+RANDSTRUCT variant) to be enabled; dropping it makes those options
+invisible and leaves them off without requiring manual intervention in
+every .config.

+## Patches
+
+### `0006-arm64-Kconfig-do-not-select-HAVE_GCC_PLUGINS.patch`
+
+Local-build workaround that makes `arch/arm64` not select
+`HAVE_GCC_PLUGINS`. **NOT for upstream** — it papers over a missing
+host-side GCC plugin dependency at build time rather than fixing the
+makepkg/distro packaging that should provide `gcc-plugin-devel` (or
+equivalent) when needed.
+
+Used on ampere when building the kernel from a clean Arch ARM userspace
+that doesn't have the gcc plugins development headers installed. The
+proper fix is to install the headers; this patch is a fallback for
+when the user wants a working kernel without touching the userspace
+package set.

+Subject: [PATCH] Bluetooth: btrtl: make RTL_SEC_PROJ read non-fatal
+
+The RTL8852B (lmp_subver=0x8852, hci_rev=0x000b, HCI_USB) does not
+support HCI vendor opcode 0xfc61 during early initialization.
+btrtl_vendor_read_reg16() returns -ENODEV, which previously caused
+btrtl_initialize() to abort with ERR_PTR(-19) and left the controller
+unconfigured — visible as a kernel Oops and "No default controller
+available" in bluetoothctl.
+
+The RTL_SEC_PROJ register encodes a key_id used to match firmware
+security-header sections.  When key_id is 0 the driver already skips
+all security headers (drivers/bluetooth/btrtl.c, case
+RTL_PATCH_SECURITY_HEADER: "If key_id from chip is zero, ignore all
+security headers").  Defaulting to key_id=0 on read failure is
+therefore safe: unsigned firmware without an embedded key continues to
+load normally, while secure-firmware paths that require a non-zero
+key_id would only be taken on chips that successfully return one.
+
+Change btrtl_initialize() so that a failed RTL_SEC_PROJ read emits an
+informational message and falls back to key_id=0 instead of aborting
+initialization.

+## Patches
+
+### `0009-Bluetooth-btrtl-make-RTL_SEC_PROJ-read-non-fatal.patch`
+
+The btrtl HCI vendor-extension code probes `RTL_SEC_PROJ` (security

+extension is absent and the read times out, currently treated as a
+fatal probe failure — the BT subsystem never comes up and the userspace
+sees no HCI device.
+
+This patch downgrades the failure to a warning so probe continues with

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The Rockchip GPIO irqchip uses irq_gc_set_wake() which only tracks the
+wake state locally in gc->wake_active.  It never calls irq_set_irq_wake()
+on the parent GIC interrupt for the GPIO bank.  During suspend,
+suspend_device_irqs() disables all non-wakeup IRQs at the GIC level, so
+GPIO-based wakeup sources (RTC alarm, PMIC power key) can never reach
+the CPU — the GPIO controller detects the interrupt but the GIC blocks it.
+
+Replace irq_gc_set_wake with rockchip_irq_set_wake that propagates the
+wake setting to the parent bank->irq via irq_set_irq_wake().  On failure,
+revert the local wake state via irq_gc_set_wake(!on) which handles
+gc->lock internally.

+### `0010a-gpio-rockchip-propagate-irq_set_wake-to-parent-GIC.patch`
+
+**WIP — sleep fixes not yet upstream-ready.** Do not include in fleet
+manifests until Markus closes the suspend/resume thread.
+
+The Rockchip GPIO irqchip uses `irq_gc_set_wake()` which only tracks
+the wake state locally in `gc->wake_active`. It never calls
+`irq_set_irq_wake()` on the parent GIC interrupt for the GPIO bank.
+During suspend, `suspend_device_irqs()` disables all non-wakeup IRQs
+at the GIC level, so GPIO-based wakeup sources (RTC alarm, PMIC power
+key) can never reach the CPU — the GPIO controller detects the
+interrupt but the GIC blocks it.
+
+This patch replaces `irq_gc_set_wake` with `rockchip_irq_set_wake`
+that propagates the wake setting to the parent `bank->irq` via
+`irq_set_irq_wake()`.

+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.
