bhnd(4): Fix bcma/siba core reset behavior

2017-11-27T22:13:30Z

Add missing support for specifying I/O control flags during core reset, and resolve a number of siba(4)-specific reset issues: - Add missing check for target reject flags in siba_is_hw_suspended(). - Remove incorrect wait on SIBA_TMH_BUSY when modifying any target state register; this should only be done when waiting for initiated transactions to clear. - Add missing wait on SIBA_IM_BY when asserting SIBA_IM_RJ. - Overwrite any previously set SIBA_TML_REJ flag when bringing the core out of reset. This fixes a lockup that occured when we brought up a core (after reboot) that had previously been placed into RESET by siba_bwn(4).

bhnd(4): implement MIPS and PCI(e) interrupt support

2017-11-21T23:15:20Z

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.

bhnd: Remove unsupported USB core IDs from the bhnd_usb device table.

This resolves a SoC reset triggered by attempting to attach to the BCM5365's USB 1.1 controller. Approved by: adrian (mentor, implicit)

sys/dev: Replace zero with NULL for pointers.

2017-02-20T03:43:12Z

Makes things easier to read, plus architectures may set NULL to something different than zero. Found with: devel/coccinelle MFC after: 3 weeks

Fix device delete child function.

2016-10-17T10:20:38Z

When detaching device trees parent devices must be detached prior to detaching its children. This is because parent devices can have pointers to the child devices in their softcs which are not invalidated by device_delete_child(). This can cause use after free issues and panic(). Device drivers implementing trees, must ensure its detach function detaches or deletes all its children before returning. While at it remove now redundant device_detach() calls before device_delete_child() and device_delete_children(), mostly in the USB controller drivers.

bhnd(4): Implement common API for IOST/IOCTL register access and core reset

2016-09-24T04:08:16Z

- Added bhnd(4) bus APIs for per-core ioctl/iost register access. - Updated reset/suspend bhnd(4) APIs for compatibility with ioctl/iost changes. - Implemented core reset/suspend support for both bcma(4) and siba(4). - Implemented explicit release of all outstanding PMU requests at the bus level when putting a core into reset.

[BHND/USB] Port of EHCI/OHCI support from ZRouter

2016-09-05T16:06:52Z

This patch adds driver implementation for BHND USB core. Driver has been imported from ZRouter project with small adaptions for FreeBSD 11. Also it's enabled for BroadCom MIPS74k boards by default. It's fully tested on Asus boards (RT-N16: external USB, RT-N53: USB bus between SoC and WiFi chips).
