Please add the following Please also add Launchpad #2170130 as the first line of the PR description. |
MT8901 EINT has a separate event mask that controls whether an EINT can be forwarded as a wake event. The current driver clears that mask only for the static SoC list, which covers the ACPI event line. Firmware-described devices can be marked wake-capable independently, so PM arms their IRQs through the normal irq_set_wake path. Clear the hardware event mask when the IRQ core enables such an EINT as a wake source so keyboard, touchpad, and other firmware-declared EINT wake sources can reach the SPM without adding board-specific EINT numbers. Restore the hardware event mask when wake is disabled, otherwise a pin that was armed once would remain an SPM wake event until reboot. Keep pins from the SoC static event-unmask list unmasked so permanently required wake events such as the ACPI event line remain armed. Make event-mask register programming opt-in for SoCs that declare support for it, and re-apply both the static list and dynamically armed wake_mask pins on resume in case the event register state is lost across system sleep. Fixes: 927eeda ("NVIDIA: SAUCE: pinctrl: mt8901: Enable ACPI wake-event EINT support") Signed-off-by: Kaushal Rajeev Butala <kbutala@nvidia.com>
