This is a residual of the $FreeBSD$ removal.

siba(4): Add support for devices have neither PMU nor PWRCTL support.

2017-11-28T00:42:44+00:00

Very early BHND Wi-Fi devices (e.g. BCM4318) do not support any form of
dynamic clock control; on these devices, any PMU requests that cannot be
met by the device's fixed clock state will return an appropriate error
code.

bhnd(4): Add a basic ChipCommon GPIO driver sufficient to support bwn(4)

2017-11-22T23:10:20+00:00

The driver is functional on both BHND Wi-Fi adapters and MIPS SoCs, but
does not currently include support for features not required by bwn(4),
including GPIO interrupt handling.

bhnd(4): extend the PMU APIs to support bwn(4)

2017-11-22T20:27:46+00:00

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.

parser.

This allows us to use the EROM parser API in cases where the standard bus
space I/O APIs are unsuitable. In particular, this will allow us to parse
the device enumeration table directly from bhndb(4) drivers, prior to
full attach and configuration of the bridge.
