[PATCH v3 00/15] pci hotplug tracking

[Vladimir Sementsov-Ogievskiy]

Hi all!

That's called v3, as it includes "[PATCH v2 0/3] pcie: cleanup code":
Supersedes: <20230207121116.325456-1-vsementsov@yandex-team.ru>
Supersedes: <20230204174758.234951-1-vsementsov@yandex-team.ru>
Supersedes: <20230207120922.325203-1-vsementsov@yandex-team.ru>

Ok, what's this about?

The main patches are the last three ones:

- introduce HOTPLUG_STATE event, that inform when hotplug controller
change it's state, especially indicator leds

- query-hotplug command, that provides same information as event on
demand

- DEVICE_ON event - a kind of counterpart for DEVICE_DELETED, signals
when device is finally accepted by guest, power indicator is on and so
on.

That's all for smarter handling of SHPC and PCIe-native hotplug.

Vladimir Sementsov-Ogievskiy (15):
  pci/shpc: set attention led to OFF on reset
  pci/shpc: change shpc_get_status() return type to uint8_t
  pci/shpc: shpc_slot_command(): handle PWRONLY -> ENABLED transition
  pci/shpc: more generic handle hot-unplug in shpc_slot_command()
  pci/shpc: pass PCIDevice pointer to shpc_slot_command()
  pcie: pcie_cap_slot_write_config(): use correct macro
  pcie_regs: drop duplicated indicator value macros
  pcie: drop unused PCIExpressIndicator
  pcie: pcie_cap_slot_enable_power() use correct helper
  pcie: introduce pcie_sltctl_powered_off() helper
  pcie: set power indicator to off on reset by default
  pci: introduce pci_find_the_only_child()
  qapi: add HOTPLUG_STATE event
  qapi: introduce DEVICE_ON event
