[PATCH 00/11] brcmfmac: cleanup and support for AP mode

[Arend van Spriel]

This patch series delivers AP mode functionality for the brcmfmac
driver. Other changes involve cleanup or minor fixes.

This series is intended for v3.7 and depends on patch sent by Dan
Carpenter identified by:

  brcmfmac: remove two obsolete structure definitions
  brcmfmac: rename structure brcmf_cfg80211_priv
  brcmfmac: remove brcmf_read_prof() function
  brcmfmac: remove brcmf_update_prof() function

Hante Meuleman (5):
  brcmfmac: use wait_event_timeout for fw control packets over usb.
  brcmfmac: use different fw api for encryption,auth. config
  brcmfmac: use define instead of hardcoded values.
  brcmfmac: notify common driver about usb tx completion.
  brcmfmac: add hostap supoort.

[PATCH 01/11] brcmfmac: use wait_event_timeout for fw control packets over usb.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

firmware control packets over usb are async acked. This is
awaited for by using interruptible wait. This can be
interrupted by signal which results in undesirable behavior.
Instead wait_event_timeout is used.

[PATCH 02/11] brcmfmac: use different fw api for encryption,auth. config

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

This patch changes the commands being used to configure
encryption and authentication. These new methods are needed
for when p2p and hostap support are added.

[PATCH 05/11] brcmfmac: get rid of extern keyword in wl_cfg80211.h

[Arend van Spriel]

The function declarations in wl_cfg80211.h used the extern keyword
but it is redundant as that is implicit so they were removed.

[PATCH 06/11] brcmfmac: use brcmf_cfg80211_priv to interface with wl_cfg80211 code

[Arend van Spriel]

The low-level driver part interfaces with wl_cfg80211 part using
brcmf_cfg80211_dev structure as handle. As brcmf_cfg80211_priv
is defined in interface it is more efficient to use that as handle
in function calls.

[PATCH 07/11] brcmfmac: remove two obsolete structure definitions

[Arend van Spriel]

The structures brcmf_cfg80211_dev and brcmf_cfg80211_iface are only
adding complexity and provide no additional value. These have been
removed in this patch.

[PATCH 09/11] brcmfmac: rename structure brcmf_cfg80211_priv

[Arend van Spriel]

Renamed structure to brcmf_cfg80211_info as it is not really a
private structure since it is exposed in header file.

[PATCH 10/11] brcmfmac: remove brcmf_read_prof() function

[Arend van Spriel]

The function brcmf_read_prof() provided access to fields
with brcmf_cfg80211_profile structure using a field id,
but the calling function can easily access that structure
directly. This patch removes the function.
