As of now OTP is being correctly parsed and the driver requires to parse pre-caldata to follow corresponding routine.
Rename cal file into pre-calfile so the board initialized correctly with API 2 board data (board-2.bin).
Also remove the now unneeded for qca9984 board.bin symlink to 5GHz calfile.

Fixes the following security vulnerabilities:
CVE-2017-8890
The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the
Linux kernel through 4.10.15 allows attackers to cause a denial of service
(double free) or possibly have unspecified other impact by leveraging use
of the accept system call.
CVE-2017-9074
The IPv6 fragmentation implementation in the Linux kernel through 4.11.1
does not consider that the nexthdr field may be associated with an invalid
option, which allows local users to cause a denial of service (out-of-bounds
read and BUG) or possibly have unspecified other impact via crafted socket
and send system calls.
CVE-2017-9075
The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel
through 4.11.1 mishandles inheritance, which allows local users to cause a
denial of service or possibly have unspecified other impact via crafted
system calls, a related issue to CVE-2017-8890.
CVE-2017-9076
The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux
kernel through 4.11.1 mishandles inheritance, which allows local users to
cause a denial of service or possibly have unspecified other impact via
crafted system calls, a related issue to CVE-2017-8890.
CVE-2017-9077
The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel
through 4.11.1 mishandles inheritance, which allows local users to cause a
denial of service or possibly have unspecified other impact via crafted
system calls, a related issue to CVE-2017-8890.
CVE-2017-9242
The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel
through 4.11.3 is too late in checking whether an overwrite of an skb data
structure may occur, which allows local users to cause a denial of service
(system crash) via crafted system calls.

For the non-working case, the code was stuck in a readl() in

because
http://lxr.free-electrons.com/source/drivers/usb/dwc3/dwc3-of-simple.c#L126
was disabling the wrong clocks when removing hcd.1 (it was disabling
the clock of hcd.0). That's why the readl() went stuck when removing
hcd.0
The patch however addresses the clock assignment from the Netgear R7500
dts file and backs off the previous attempt.
Now unloading and repeated module loading is working just fine.

Split the fritz-tools into subpackages. fritz_tffs_read is usefull for
all Fritz boards where fritz-cal_extract is only required for the
Fritz 4040 at the moment.
Rename the tffs related binary to the more catchy name fritz_tffs and
move the whole package to utilities since the package doesn't really
provide a firmware file.
Make the fritz-tools available for all targets and build them shared.
The tffs is used by avm on lantiq and ar71xx as well.

This patch adds support for AVM FRITZ!Box 4040.
hardware highlights:
SOC: IPQ4018 / QCA Dakota
CPU: Quad-Core ARMv7 Processor rev 5 (v7l) Cortex-A7
DRAM: 256 MiB Nanya NT5CC128M16IP

Serial:
WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!
The Serial setting is 115200-8-N-1. The SoC's serial port is right
next to the MXIC FLASH chip. The board has a unpopulated 1x4 0.1"
header for it. Use a multimeter to figure out the pinout!
This board currently needs an additional u-boot image in order to boot
properly. Booting with EVA isn't possible ATM.
Install Procedure:
0. It's highly recommended to connect to the serial port.
The serial settings are listed above.
1. install a u-boot image for AVM Fritz!Box 4040
(see <https://github.com/chunkeey/FritzBox-4040-UBOOT/releases> and
<https://github.com/chunkeey/FritzBox-4040-UBOOT/blob/master/upload-to-f4040.sh>)
2. upload the initramfs.itb image via tftp (u-boot listens to
192.168.1.1 - use binary transfer mode!)
3. connect to the FB4040 and use sysupgrade sysupgrade.bin
to install the image.
Works:
- Switch and Ethernet (99%)
- Buttons (WLAN, WPS)
- FLASH (1 x 32MiB NOR Chip)
- WLAN2G and WLAN5G
- CPUFREQ scaling
- PRNG
- serial
- Crypto Accelerator
- sysupgrade (Read the flash instructions to avoid bricking)
- full LEDE Install (Read the flash instructions to avoid bricking)
- LEDs (Power, WAN, Info (red and amber), LAN)
The LEDs are connected to the QCA8075 LED ports.
The AR40xx driver contains a gpio-controller to
handle these special "GPIOs".
- USB Both 3.0 and 2.0 ports
- many packages from other ARMv7 boards
(This does include the RaspberryPi Model 2!)

Add back support for the independent_clocks definition that has been
removed between kernel 4.4 and 4.9 by upstream commits
eb96924acddc709db58221c210ca05cd9effb1df and
e86eee6bc2aaa6b3637f6497b26beee09a91bde9
* extend the new cpufreq_dt_platform_data definition in cpufreq-dt.h
* revert the removal of its usage in cpufreq-dt.c
* use new cpufreq-dt.h in qcom-cpufreq.c

For IPQ806x targets, TZ protects the registers that are used to
configure the routing of interrupts to a target processor.
To resolve this, this patch uses scm call to route GPIO interrupts
to application processor. Also the scm call interface is changed.

At the moment as a workaround definition for scm firmware in DT is used as if it is
apq8064 board. This leads to incomplete scm firmware initialization and as a result
cpuidle driver fails to configure.
By design unlike other qcom boards ipq do not use clocks to connect to scm.
Considering this we're removing from DT and scm driver clocks for ipq boards.
As a result cpuidle does not produce errors about failed configuration anymore.

The available amount of coherent DMA memory is very limited. On Linux
4.4 this issue was worked around by increasing the pool size.
It turns out that using coherent memory here is completely unnecessary.
This change reworks the driver code to use kzalloc+dma_map_single
instead.

Do not patch upstream files, overwrite them entirely. The upstream files
are buggy for a number of devices and this significantly simplifies the
patch structure
