* use kernel buildin transfer_one_message. we only need to implement
transfer_one and set_cs function
* should support use gpio as cs pin
* deselected the spi device when setup and add debug info
* only reset device when first driver probe

before spi transfer. use spi_prepare_message to setup spi hardware. it
will setup MSB, spi mode and speed
remove sys_freq member and speed check code

* fill struct according to the member order
* add error clean up
* set min/max spi speed. so we don't need to check again

use loops_per_jiffy, spi clock speed and write bytes to get the
spi loop count. if loop to 0 than spi operation timeout.
remove usleep. we only write 1 byte to spi device. use busy loop
would be better.

This patch adds the posibility to config the led behaviour of the lantiq phys
over the devicetree bindings.It patches the 0023-NET-PHY-adds-driver-for-lantiq-PHY11G
for 3.18 and 4.1. I have also added a register description overview for
applicable values. This goes to the documentation folder in the linux kernel.

It turned out that mtk_nand driver uses some sophisticated accounting and a
general nand code must be patched.
This patch adds required read and erase calls to a general nand code. I
used a code for re6500 released by Linksys as a reference.
All required operations (erase, write and read) are usable. However I found
that jffs2 filesystem can be created only on top of a ubi volume. I tried
to create jffs2 directly on mtd device but pages with clean markers are
became uncorrectable.

All RTC drivers require the kernel to be built with CONFIG_RTC_CLASS=y.
Set it accordingly.
Tested only with DS1307.

This patch improves the default configuration of DWC2 on lantiq SoCs
somewhat:
* Set maximum packet count to largest allowed value by the DWC2 (511)
* Use 16-bit DMA bursts
* Divide fifo buffers more evenly
Default fifo buffer sizes from original ltq-hcd driver seem really
irrational. For example according to DWC2 data book rxfifo size of 240
will not fit even a single full length USB packet. On the other hand
non-periodic tx fifo size of 240 is more than enough to fit one complete
packet.
Change the sizes around to improve the situation and to fix some issues
especially with isochronous USB transfers.

The hwid check was wrong, causing the AR71XX_MODEL value to end with a

When fixing the model string for WNDR3700v2 which contain a model string
followed by 0xff in r46455, the match for other versions of the WNDR3700v2
which just contain lots of 0xff broke (as the 0xff $model is checked for
is stripped off).
Fix by stripping off non-printable characters only for the actual output
string, but not for the internal matching.
