Because the oldest supported kernel version on the ar71xx target is 4.4,
the condition that the kernel version is smaller than 3.15.0 is always
false. Remove the obsolete checks from the target specific source files
to clean up the code a bit.

Commit c312cef223 ("ar71xx: spi-rb4xx fix.") replaced the clk_enable() call
with clk_prepare_enable() to meet the common clock framework requirements.
However it did not change the clk_disable() call in the error patch which
thus leads to imbalance.
Fix the code by using the correct counterpart of clk_prepare_enable() in both
places.

Qualcomm claims this reduces cache misses. Original commit message below:

Subject: [ag71xx] reduce NAPI weight
In an attempt to increase our cache warmth, we are decreasing NAPI.
This increases the warmth of the reused SKBs.

The motivation for this was misguided. It turns out tuning the NAPI weight could be useful for testing purposes. Therefore reverting.

This reverts commit 13e5e47369.
This commit causes a severe regression in LAN->WAN routing performance
for several devices. This appears to be caused by the extra requirement
to validate the SKB checksum early in the rx path, which the ethernet
hardware does not do

This add support for kernel 4.9 to the ar71xx target.
It was compile tested with the generic, NAND and mikrotik subtarget.
Multiple members of the community tested it on their boards and did not
report any major problem so far.
Especially the NAND part received some changes to adapt to the new
kernel APIs. The serial driver hack used for the Arduino Yun was not
ported because the kernel changed there a lot.

On a TL-WN710N, this patch increases iperf performance from ~92.5 to ~93.5 mbps. Keep in mind the WN710N is a 100mbps device. I expect greater numbers from gigabit devices.

Teltonika RUT900 is a Router with LTE dual SIM, WiFi, 4x Ethernet
ports, I/O, RS232, RS485, GPS.
The device ist based on a Atheros AR9344 rev 3,
Specifications:
- 560/450/225 MHz (CPU/DDR/AHB)
- 128 MB of RAM
- 16 MB of FLASH
- Serial Console header on a Card Board edge connector
- 4x 10/100 Mbps Ethernet (3x LAN, 1x WAN)
- 2.4 GHz Wifi
- 2x external, detachable Wifi antennas
- LTE Modem Huawei ME909u-521 (Also other Modem seen)
- 2x LTE antennas
- 1x GPS antenna
- 7x LED, 1x button
- 1x USB Connector
- 1x Serial RS232
- 1x Serial RS485
- 1x MicroSD Card
The GPL sources of the device are available at www.teltonika.lt/gpl/
and are based on OpenWRT Barrier Breaker (14.07)
Running from tftp:
The Router starts into the uboot Webupdater if the Button ist pressed
more than 3 seconds, if no Network cable is attached it starts the
uboot serial console, from there the router loads the firmware image
via tftpboot from 192.168.1.2:firmware.bin (the router has the
192.168.1.1). With bootm the loaded image will be booted.

Remove the wget2nand script, drop the need for manual installation,
use sysupgrade instead.
There are now two different NAND images, one for 64 MiB flashes, the
other for >= 128 MiB

This board is very old and unlikely to still be relevant today. Support
for it contains a significant amount of device specific baggage which is

In new kernels we should use clk_prepare_enable instead of clk_enable
since clk_enable does not make proper initialization that leads
to rise WARN_ON messages and not working spi bus on the device.
