* bus: Document special ranges of IVARsJohn Baldwin2026-02-171-1/+1
| | | | | | | | | | | | | Some IVAR indices are special in that they have global meaning across multiple buses where as other IVARs are always private to the local bus. Try to document this a bit and add constants for the various ranges to avoid future conflicts. This is a no-op, but IVAR indices are now generally defined as enums as that makes it easier to define them in terms of ranges.

* mii: Change e1000phy (Marvell 88E1000) PHYs to disable power down / isolateAdrian Chadd2025-05-011-0/+7
| | | | | | | | | | | | | | | The reset sequence doesn't clear the power down / isolate bits during power up and configuration. Change that to make sure things are consistent. If the PHY is initialised by something external (eg a bootloader, config EEPROM driving a switch chip, etc) which sets the power down and/or isolate bits in E1000_CR, then the reset path wouldn't undo it and the PHY will look permanently down. Even when we configure autonegotiate or statically nail the port up, it's still not coming out of the power mode. Differential Revision: https://reviews.freebsd.org/D50045

* Extend device_get_property APIKornel Duleba2022-03-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | In order to support various types of data stored in device tree properties or ACPI _DSD packages, create a new enum so the caller can specify the expected type of a property they want to read, according to the binding. The bus logic will use that information to process the underlying data. For example in DT all integer properties are stored in BE format. In order to get constant results across different platforms we need to convert its endianness to match the host. Another example are ACPI_TYPE_INTEGER properties stored as uint64_t. Before this patch the ACPI logic would refuse to read them if the provided buffer was smaller than 8 bytes. Now this can be handled by using DEVICE_PROP_UINT32 type. Modify the existing consumers of this API to reflect the changes and update the man pages accordingly.
