The firmware for brcmfmac devices includes information regarding
regulatory constraints. For certain devices this information is kept
separately in a binary form that needs to be downloaded to the device.
This patch adds support to download this so-called CLM blob file. It
uses the same naming scheme as the other firmware files with extension
of .clm_blob.

The CLM blob file is optional. If the file does not exist, the download
process will be bypassed. It will not affect the driver loading.

broken_sg_support, sd_head_align, and sd_sgentry_align are used in
brcmfmac code but not configurable in dts file. Add the parsing logic.
Now they can be configured like below in dts:
	brcm,broken_sg_support;
	brcm,sd_head_align = /bits/ 16 <4>;
	brcm,sd_sgentry_align = /bits/ 16 <4>;

Firmware returns proprietary error code when getting error in
fil_cmd_data_set or fil_cmd_data_get. Sometimes the vendor tool or
utilities which uses libnl may stuck in some commands when wl is down.
For example, issue "scan" command after issuing "down" command, the
"scan" command will be the blocking call and stuck as no response from
firmware. It is caused by that firmware returns BCME_NOTUP(-4) when wl
is down, but in Linux the -4 is -EINTR, so libnl catches the error and
not pass to upper layer.
Because of that, the driver should return Linux error code instead of the
proprietary error code, and the tools or utilities need to get the real
firmware error code by another command "bcmerrorstr" after receiving
the error.

APSTA can work on two band concurrently with using VSDB(Virtual
Simultaneous Dual-Band) or RSDB(Real Simultaneous Dual-Band) features.
In this case, we have to keep apsta is 1 in firmware side.
If we start wpa_supplicant on wlan0 and then start hostapd on wlan1, the
apsta will be set to 0, and data will be stall on wlan0(station).
Because that, we only set apsta to 0 when AP start on primary interface.

…bled

For legacy chips w/o CLM blob files, kernel with user helper function
enabled returns -EAGAIN when we request_firmware() for blob file:
"request_firmware() -> _request_firmware() -> fw_load_from_user_helper()
-> _request_firmware_load() -> retval=-EAGAIN"
We should do retries and also continue brcmf_c_process_clm_blob if
getting -EAGAIN from request_firmware function.

The buffer size of return of cap iovar is greater than 256 bytes in
some firmares. For instance, the return size of cap iovar is 271 bytes
in 4373 13.10.246.79 firmare. It makes caps buffer is default value and
cause the feature capability parsing failed.
Because of that, we enlarge caps buffer size to 512 bytes and add
the error print for cap iovar error.

Linux 3.6 introduces TSQ which has a per socket threshold for TCP Tx
packet to reduce latency. In fcmode 1/2, host driver enqueues skb in
hanger and TCP doesn't push new skb frees until host frees the skb when
receiving fwstatus event. So using skb_orphan before sending skb to bus
will make the skb removing the ownership of socket. With this patch, we
got better throughput in fcmode 1/2.

Tested 43455 TCP throughput in 20 MHz bandwidth with/without this patch.
fcmode 0: 59.5 / 59.6 (Mbps)
fcmode 1: 59.3 / 23.4 (Mbps)
fcmode 2: 59.6 / 21.5 (Mbps)

…DP RX Traffic.

The number of words that the read FIFO has to contain except
the end of frame before sends data back to the host.
Max watermark = (512B - 2* (BurstLength))/4 =
(512 - 128)/4 = 384/4 = 0x60
so if burst length (i.e. BurstLength = 64) is increased,
watermark has to be reduced. This is the optimal setting for this chip.

user can set scheduling  priority for sdio_dpc. It can improve RX

When eap_restrict is enabled, firmware will toss non-802.1x frames from
tx/rx data path if station not yet authorized.
Internal firmware eap_restrict is disabled by default. This patch makes
it possible to enable firmware eap_restrict by specifying
eap_restrict=1 as module parameter.

FMAC driver need to provide a dummy wowlan filter for kernel and
provided the well configured wowlan stack. So the system will
keep driver in connected state in suspend mode and can be wake

Convert the driver over the the device model component framework, making
use of the drm encoder/connector helpers. This allows adihdmi to be
dynamically selected as an external encoder for drm drivers like tilcdc
that support the DT graph binding which defines ports and remote-endpoints
to attach external encoders.

Also, this driver was modified by another developer to support audio and
tweak some settings.  Along the way it seems to have been reformatted to
4 space tabs which is hard to work with alongside the standard 8 space tabs
in the kernel coding standard. As such, this is reformatted to standard 8
space tabs so it's a bit more readable.

The component and audio support should be merged into the upstream driver
so this adihdmi driver can be removed.

We have errata i688 workaround produce warnings on SoCs other than
omap4 and omap5:

omap4_sram_init:Unable to allocate sram needed to handle errata I688
omap4_sram_init:Unable to get sram pool needed to handle errata I688

This is happening because there is no ti,omap4-mpu node, or no SRAM
to configure for the other SoCs, so let's remove the warning based
on the SoC revision checks.

As nobody has complained it seems that the other SoC variants do not
need this workaround.
