Merge branch 'acpi-init'
* acpi-init: clocksource: cosmetic: Drop OF 'dependency' from symbols clocksource / arm_arch_timer: Convert to ACPI probing clocksource: Add new CLKSRC_{PROBE,ACPI} config symbols clocksource / ACPI: Add probing infrastructure for ACPI-based clocksources irqchip / GIC: Convert the GIC driver to ACPI probing irqchip / ACPI: Add probing infrastructure for ACPI-based irqchips ACPI: Add early device probing infrastructure
