[PATCH 1/3] clocksource/drivers/arm_arch_timer_mmio: Prevent driver unbind

From: Johan Hovold

Date: Tue Nov 11 2025 - 10:33:53 EST


Clockevents cannot be deregistered so suppress the bind attributes to
prevent the driver from being unbound and releasing the underlying
resources after registration.

Fixes: 4891f01527bb ("clocksource/drivers/arm_arch_timer: Add standalone MMIO driver")
