[PATCH 00/18] brcmfmac: sdio rework and msgbuf protocol changes

[Arend van Spriel]

This series consists mostly of cleanup in SDIO driver code. Other changes
are preparing to new firmware protocol called msgbuf, which is intended
for PCIe fullmac devices.

Arend van Spriel (14):
  brcmfmac: add missing curly braces in brcmf_fws_txstatus_suppressed()
  brcmfmac: combine bcmsdh source files into one
  brcmfmac: remove unnecessary function prototypes
  brcmfmac: remove unused struct brcmf_sdio_dev::func_cis_ptr attribute
  brcmfmac: use sdio functions to enable/disable F2
  brcmfmac: remove brcmf_sdio_regrw_helper() from header file
  brcmfmac: remove regs parameter from sdio probe functions
  brcmfmac: get rid of some void pointer parameters
  brcmfmac: remove brcmf_sdio_wdtimer_enable() function
  brcmfmac: use consistent function names in bcmsdh.c
  brcmfmac: reduce function parameters in sdio send/receive calls
  brcmfmac: use consistent function names in dhd_sdio.c
  brcmfmac: remove brcmf_sdio_disconnect() function
  brcmfmac: clarify struct brcmf_sdio_dev::func[0] reference

Hante Meuleman (4):
  brcmfmac: Move common BCDC code in single function.
  brcmfmac: Fix hex dump for FWIL.
  brcmfmac: Add definition of new protocol layer msgbuf.
  brcmfmac: Combine protocol push hdr and bus txdata.

[PATCH 01/18] brcmfmac: add missing curly braces in brcmf_fws_txstatus_suppressed()

[Arend van Spriel]

The 0-day testing from Fenguang Wu issued the following warning:

This warning is valid and the if statement needs curly braces here.

[PATCH 02/18] brcmfmac: combine bcmsdh source files into one

[Arend van Spriel]

The driver has four files specific to SDIO host interface handling.
This commit reduces that by merging two closely related source files.

[PATCH 03/18] brcmfmac: remove unnecessary function prototypes

[Arend van Spriel]

With the merge of bcmsdh.c and bcmsdh_mmc.c several function prototypes
are no longer necessary and can be removed. Consequence is reordering
some of the functions.

[PATCH 04/18] brcmfmac: remove unused struct brcmf_sdio_dev::func_cis_ptr attribute

[Arend van Spriel]

During the SDIO probe the func_cis_ptr attribute in struct brcmf_sdio_dev
is being determined, but it is never used after that. Removing it also
obsoletes two functions in bcmsdh.c.

The chip recognition requires a base address that was provided
to it during the probe. However, the address is a fixed define
value so it is unnecessary to pass through the probe functions.

[PATCH 08/18] brcmfmac: get rid of some void pointer parameters

[Arend van Spriel]

In sdio code a couple of functions use a void pointer as argument
type although it should be struct brcmf_sdio. Changing the functions
to have proper type checking.

Functions in bcmsdh.c that are called with struct brcmf_sdio_dev
instance are renamed consistently with brcmf_sdiod_ prefix. Also
removing brcmf_sdioh_attach/detach() functions and merge it with
brcmf_sdiod_probe/remove().

[PATCH 11/18] brcmfmac: reduce function parameters in sdio send/receive calls

[Arend van Spriel]

The SDIO send and receive functions in bcmsdh.c are always called
with the same parameters. For the driver there is no use-case
to call them otherwise so remove those parameters from function
prototypes.

[PATCH 12/18] brcmfmac: Move common BCDC code in single function.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

The BCDC functions query_dcmd and set_dcmd both create a msgbuf to
be sent to dongle this code is very similar and for optimisation
best put in a function.

[PATCH 13/18] brcmfmac: Fix hex dump for FWIL.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

The debug function brcmf_dbg_hex_dump API got changed and the
information string should preferably contain a \n at the end
of the string. Update the FWIL so debug output looks better.

[PATCH 14/18] brcmfmac: Add definition of new protocol layer msgbuf.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

A new protocol layer msgbuf will be added in the future. This
change makes it possible to select the desired layer by the
bus driver. USB and SDIO will select BCDC. At the moment
nothing is being done with this information.

[PATCH 15/18] brcmfmac: Combine protocol push hdr and bus txdata.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

For the transmission of data a protocol push hdr is performed
followed by a bus txdata call. For the new protocol msgbuf this
is not workable. Since they are already "loosely" coupled for
bcdc protocol they are combined. This means that txdata will
go "through" the protocol layer and a seperate protocol push
hdr will not be needed anymore.

and call it directly.

[PATCH 18/18] brcmfmac: clarify struct brcmf_sdio_dev::func[0] reference

[Arend van Spriel]

The struct brcmf_sdio_dev contains array of sdio functions that
are used in the driver. However, during probe func[0] entry was
assigned to the function 1 reference. This was corrected upon
doing the actual I/O access. This patch makes it more clear by
creating the func[0] entry properly and use it as is during
I/O access.

Probably needless to say, but saying it anyway ;-). This patch series is 
intended fro 3.14. It applies to the master branch of the wireless-next
