* bhnd_bus_*_resource: Remove redundant type and rid argumentsJohn Baldwin2025-12-095-22/+13
| | | | | | | | | | | | | | Remove type and rid arguments from bhnd_bus_(activate|deactivate|release)_resource. This should have been done earlier to match the changes made to bus_release_resource, etc. While fixing up the callers, remove rid members from softc structures since the only time a value is needed is as a constant input to bhnd_bus_alloc_resource*.

* gpio: remove gpiobus_attach_busAhmad Khalifa2025-08-131-1/+3
| | | | | | | | | | | | Since gpiobus_attach_bus can attach the gpiobus child along with its children in the same bus pass, the parent controller's reference to gpiobus might not be set by the time the children need it. Instead, drivers should use gpiobus_add_bus and explicitly call bus_attach_children.

* bus_generic_detach: Delete children after detaching themJohn Baldwin2025-01-021-3/+0
| | | | | | | | | | | | | | | | | This provides better semantics as a standalone DEVMETHOD for device_attach as bus drivers should remove child devices they created as part of detach cleanup. The implementation calls bus_detach_children() first to permit child devices an opportunity to veto the detach operation. If that succeeds, device_delete_children() is used to delete the child devices. This requires fixing various drivers that were deleting devices explicitly (via a device_t pointer cached in the softc) after calling bus_generic_detach to stop doing that and just rely on bus_generic_detach to remove child devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bwn(4) driver requires a number of extensions to the bhnd(4) PMU interface to support external configuration of PLLs, LDOs, and other parameters that require chipset or PHY-specific workarounds. These changes add support for: - Writing raw voltage register values to PHY-specific LDO regulator registers (required by LP-PHY). - Enabling/disabling PHY-specific LDOs (required by LP-PHY) - Writing to arbitrary PMU chipctrl registers (required for common PHY PLL reset support). - Requesting chipset/PLL-specific spurious signal avoidance modes. - Querying clock frequency and latency. Additionally, rather than updating legacy PWRCTL support to conform to the new PMU interface: - PWRCTL API is now provided by a bhnd_pwrctl_if.m interface. - Since PWRCTL is only found in older SSB-based chipsets, translation from bhnd(4) bus APIs to corresponding PWRCTL operations is now handled entirely within the siba(4) driver. - The PWRCTL-specific host bridge clock gating APIs in bhnd_bus_if.m have been lifted out into a standalone bhnd_pwrctl_hostb_if.m interface.

* bhnd(4): implement MIPS and PCI(e) interrupt supportLandon J. Fuller2017-11-214-37/+119
| | | | | | | | | | | | | | | | | | | | | | On BHND MIPS SoCs, this replaces the use of hard-coded MIPS IRQ#s in the common bhnd(4) core drivers; we now register an INTRNG child PIC that handles routing of backplane interrupt vectors via the MIPS core. On BHND PCI devices, backplane interrupt vectors are now routed to the PCI/PCIe host bridge core when bus_setup_intr() is called, where they are dispatched by the PCI core via a host interrupt (e.g. INTx/MSI). The bhndb(4) bridge driver tracks registered interrupt handlers for the bridged bhnd(4) devices and manages backplane interrupt routing, while delegating actual bus interrupt setup/teardown to the parent bus on behalf of the bridged cores.

| | | | | | | | | | | | | | | | | | Add bhnd(4) API for explicitly registering BHND platform devices (ChipCommon, PMU, NVRAM, etc) with the bus, rather than walking the newbus hierarchy to discover platform devices. These devices are now also refcounted; attempting to deregister an actively used platform device will return EBUSY. This resolves a lock ordering incompatibility with bwn(4)'s firmware loading threads; previously it was necessary to acquire Giant to protect newbus access when locating and querying the NVRAM device.

This is an analogue to the existing bhnd_erom_probe_static() method, and allows the bhndb bridge to discover the best available erom parser class prior to newbus probing of its children. - Add support for supplying identification hints when probing erom devices. This is required on early EXTIF-only chipsets, where chip identification registers are not available. - Migrate bhndb over to the new bhnd_erom API, using bhnd_core_info records rather than bridged bhnd(4) device_t references to determine the bridged chipsets' capability/bridge configuration. - The bhndb parent (e.g. if_bwn) is now required to supply a hardware priority table to the bridge. The default table is currently sufficient for our supported devices. - Drop the two-pass attach approach we used for compatibility with bhndb(4) in the bhnd(4) bus drivers, and instead perform bus enumeration immediately, and allocate bridged per-child bus-level resources during that enumeration.
