Rafał Miłecki 5a1c18b761 bcma: keep a direct pointer to the struct device
Accessing struct device is pretty useful/common so having a direct
pointer:
1) Simplifies some code
2) Makes bcma_bus_get_host_dev() unneeded
3) Allows further improvements like using dev_* printing helpers

Denis 'GNUtoo' Carikli 985324a16e bcma: add HP Stream Notebook
In this laptop we have the following PCI device:

	[...]
	Region 0: Memory at 91000000 (64-bit, non-prefetchable) [size=32K]
	[...]

With this patch, we can now see its WiFi chip:

Rafał Miłecki 1bea0512c3 bcma: add PCI ID for Foxconn's BCM43142 device
After discovering there are 2 very different 14e4:4365 PCI devices we
made ID tables less generic. Back then we believed there are only 2 such
devices:
1) 14e4:4365 1028:0016 with SoftMAC BCM43142 chipset
2) 14e4:4365 14e4:4365 with FullMAC BCM4366 chipset

>From the recent report it appears there is also 14e4:4365 105b:e092
which should be claimed by bcma. Add back support for it.

Rafał Miłecki 8369ae33b7 bcma: add Broadcom specific AMBA bus driver
Broadcom has released cards based on a new AMBA-based bus type. From a
programming point of view, this new bus type differs from AMBA and does
not use AMBA common registers. It also differs enough from SSB. We
decided that a new bus driver is needed to keep the code clean.

In its current form, the driver detects devices present on the bus and
registers them in the system. It allows registering BCMA drivers for
specified bus devices and provides them basic operations. The bus driver
itself includes two important bus managing drivers: ChipCommon core
driver and PCI(c) core driver. They are early used to allow correct
initialization.

Currently code is limited to supporting buses on PCI(e) devices, however
the driver is designed to be used also on other hosts. The host
abstraction layer is implemented and already used for PCI(e).

Support for PCI(e) hosts is working and seems to be stable (access to
80211 core was tested successfully on a few devices). We can still
optimize it by using some fixed windows, but this can be done later
without affecting any external code. Windows are just ranges in MMIO
used for accessing cores on the bus.
