Bring this branch onto current main. The merge keeps the other side's tree; the next commit carries the reworked version of this branch's change.
A7-A9 have no EL2 and boot without any PSCI firmware, so Linux on an iPad 5 could not bring secondary CPUs down and up again, and a kexec had nowhere to park them. CPU hotplug, kexec and a clean poweroff all need a PSCI implementation that stays resident after m1n1 hands over. Carry m1n1 patches that keep a small EL3 PSCI implementation resident: CPU_ON/CPU_OFF with a firmware rendezvous (EL1 WFI/WFE trap to EL3), SYSTEM_OFF, and a guarded SYSTEM_RESET that boots the default entry again. The loader marks retained hardware in the device tree after a PSCI re-entry. The resident PSCI is on by default on these SoCs; the shipped boot framing keeps psci_reset=0, so SYSTEM_RESET stays off unless a loader enables it. Adds boot/m1n1/psci-loader and its tests.

Bring this branch onto current main and the series it depends on. The merge keeps the other side's tree; the next commit carries the reworked version of this branch's change.
The A9 AOP hosts the accelerometer, gyroscope, pressure and ambient-light sensors. Its firmware needs boot arguments and per-device calibration that m1n1 did not pass on S8003, and a reloaded AOP (after kexec or sleep) lost its sensor firmware state, so the sensors did not come back. m1n1 passes the A9 AOP boot arguments and sensor calibration. The kernel selects a certified AOP reload path through device-tree match data (bindings, DT, mailbox, pmdomain, IIO and AOP driver patches), keeps the AOP power domain and firmware state for that reload, and refuses a suspend that would interrupt the firmware's boot. The J71t firmware recipe gains the AOP pieces, the gyroscope and pressure drivers are enabled, and J71t's accelerometer and gyroscope move from missing to working, and its light sensor from untested to working.

The TriStar charger subscribed to the PMU's RTC event 16 for source identification. An acknowledgement there could take the RTC's wake event, and the polled cover inputs had no driver enabled. Give RTC event 16 to the RTC alone and keep the PMU and RTC event split (DT, RTC and USB patches), so one consumer's acknowledgement cannot take the other's wake event. Enable KEYBOARD_GPIO_POLLED for the polled cover inputs. Assisted-by: LLM

The iPad 5 device tree has described its two Smart Cover lines as gpio-keys-polled devices since the A9 support landed, but the configs never built that driver, so no cover input existed. Build it on both 16K and 4K configs, which share one option set. From orchard PR #103 (commit 190bb13), config part only.

Part 3 of 23 of the iPad 5 (J71t) series in this repository; merge after #101.
Problem
The TriStar charger subscribed to the PMU's RTC event 16 for source identification. An acknowledgement there could take the RTC's wake event, and the polled cover inputs had no driver enabled.
Change
Give RTC event 16 to the RTC alone and keep the PMU and RTC event split (DT, RTC and USB patches), so one consumer's acknowledgement cannot take the other's wake event. Enable KEYBOARD_GPIO_POLLED for the polled cover inputs.
Testing
Dependencies
Depends on #101.
This branch is stacked on the PRs it depends on and carries their commits; the change of this PR is its last commit, "j71t: One owner for the PMU and RTC wake interrupts".
This update keeps the branch's earlier history: it merges the current base into the branch and adds the reworked change as a new commit on top.
