Subject: [PATCH v4 0/4] x86/platform/intel-mid: Fix RTC / WDT handling

Current RTC approach breaks some platforms. Rewrite it completely and
make avaiable only for intended platforms.

Tested on Intel Merrifield, ASuS T100TA (normal and acpi=off cases).

Since v3:
- move to arch_initcall()
- do the same for watchdog registration code (new patch 4)

Since v2:
- add mp_map_gsi_to_irq() fix to the series as patch 1
- add patch 3
- rewrite RTC approach as another platform code for Intel MID

Andy Shevchenko (4):
  x86/ioapic: Return suitable error code in mp_map_gsi_to_irq()
  x86/platform/intel-mid: Allocate RTC interrupt for Merrifield
  x86/platform/intel-mid: Don't shadow error code of mp_map_gsi_to_irq()
  x86/platform/intel-mid: Move watchdog registration to arch_initcall()
