3e9ecdffc1 Cleanup evdev support for TI ADC/TS
- evdev_set_methods call is not required if actual methods are no-ops
- evdev_set_serial is also optional if there is no meaningful input device
    identifier
- evdev_set_id on the other hand is mandatory, so set virtual bus with
    dummy vendor/product/version

TI says that the bandgap sensor is not very accurate on AM335x, but in our

28257ccca8 INTRNG: Rework handling with resources. Partially revert r301453.
- Read interrupt properties at bus enumeration time and store
   it into global mapping table.
 - At bus_activate_resource() time, given mapping entry is resolved and
   connected to real interrupt source. A copy of mapping entry is attached
   to given resource.
 - At bus_setup_intr() time, mapping entry stored in resource is used
   for delivery of requested interrupt configuration.
 - For MSI/MSIX interrupts, mapping entry is created within
   pci_alloc_msi()/pci_alloc_msix() call.
 - For legacy PCI interrupts, mapping entry must be created within
   pcib_route_interrupt() by pcib driver itself.

23a2d5f593 Add OF_prop_free function as a counterpart for OF_*prop_alloc
- Introduce new OF API function OF_prop_free to free memory allocated by
  OF_getprop_alloc and OF_getencprop_alloc. Current code just calls free(9)
  with M_OFWPROP memory class which assumes knowledge about OF_*prop_alloc
  functions' internals and leads to unneccessary code coupling

- Convert some of the free(..., M_OFWPROP) instances to OF_prop_free

hardware. The rest of free(..., M_OFWPROP) instances will be handled with

ee35e13013 INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

11cdd44a03 Remove FDT specific parts from INTRNG. Change its interface to make it
universal.

(1) New struct intr_map_data is defined as a container for arbitrary
description of an interrupt used by a device. Typically, an interrupt
number and configuration relevant to an interrupt controller is encoded
in such description. However, any additional information may be encoded
too like a set of cpus on which an interrupt should be enabled or vendor
specific data needed for setup of an interrupt in controller. The struct
intr_map_data itself is meant to be opaque for INTRNG.

(2) An intr_map_irq() function is created which takes an interrupt
controller identification and struct intr_map_data as arguments and
returns global interrupt number which identifies an interrupt.

(3) A set of functions to be used by bus drivers is created as well as
a corresponding set of methods for interrupt controller drivers. These
sets take both struct resource and struct intr_map_data as one of the
arguments. There is a goal to keep struct intr_map_data in struct
resource, however, this way a final solution is not limited to that.

(4) Other small changes are done to reflect new situation.

This is only first step aiming to create stable interface for interrupt
controller drivers. Thus, some temporary solution is taken. Interrupt
descriptions for devices are stored in INTRNG and two specific mapping
function are created to be temporary used by bus drivers. That's why
the struct intr_map_data is not opaque for INTRNG now. This temporary
solution will be replaced by final one in next step.

4e5b50116d Fix fallout from r292180 (Dec 2015)... ensure that every driver which has
a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc.  This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).

(Thanks to jilles@ for providing the vital clue about the kernel linker.)

a5df0b9c3f Add support for dual emac mode.
In dual emac mode, the CPSW subsystem provides two independent ethernets.

This is implemented (as recommended by TI's TRM) with a mixture of switch
settings (vlans) and specific features of CPSW subsystem.

The driver was splitted to accommodate the shared parts (RX and TX rings
for example) while it still provides two independent ethernets.

Each of the ethernet ports driver has it's own set of MDIO registers among
the other private settings.

Previously this driver always operate in promisc mode, now the Switch ALE
(address table entry) is properly initialized and enabled.

The driver is also tested (and known to work) with both ports operating in
single port mode (active_slave 0 or 1).

Tested on uBMC (dual emac mode, both ports in single mode, giga and fast
ethernet) and BBB (single port, fast ethernet).
