Laszlo Nagy 4ce153e6e1 all/system_top.v: loopback gpio lines
Create loopback on unused GPIO lines since Linux may rely on it.

Laszlo Nagy 31318cf311 all/system_top.v: drive unused gpio inputs with zero
The loopback on the unused gpio inputs consumes routing resources
while does not gives any value for the software.

Connect these lines to zero instead.

Laszlo Nagy fa7c85a9eb all: Drive undriven input signals, complete interface
- connect unused GPIO inputs to loopback
- connect unconnected inputs to zero
- complete interface for system_wrapper instantiated in all system_top

fixes incomplet portlist WARNING [Synth 8-350]
fixes undriven inputs WARNING [Synth 8-3295]

The change excludes the generated system.v and Xilinx files.

AndreiGrozav ebae8bf8c1 Remove interrupts from system_top for all xilinx projects
- remove interrupts from system_top
- for all suported carriers:
	- remove all interrupt bd pins
	- connect to GND all initial unconnected interrupt pins
- update ad_cpu_interrupt procedure to disconnect a interrupt from GND
before connectiong it to another pin.

Istvan Csomortani 9055774795 all: Update license for all hdl source files
All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.

New license looks as follows:

Istvan Csomortani 10d9de39a1 axi_ad9361/tdd: Update the synchronization logic

Istvan Csomortani bcee3e04d4 fmcomms2_tdd: Update tdd_enabaled path
This line controls the mux, which switch between hdl and software (GPIO) control of the ENABLE/TXNRX pins.
Fix the broken path and change the name from "tdd_enable" to "tdd_enabled".

Istvan Csomortani d2c99acae8 fmcomms2/TDD: Update synchronization interface
Synchronization is done by a simple req/ack interface between a master and slave terminal.

Istvan Csomortani 8e631e56d6 fmcomms2: Add a synchronization interface for TDD mode.
Supported carrier are ZC706 and RFSOM.
The synchronization pulse is automatically generated by the master terminal, when TDD mode is enabled.
By default a terminal is slave, software must write  0x01 into TDD register 0x50.

Istvan Csomortani 0102e3e02c fmcomms2_ALL: Preserve backward compatibility for ENABLE/TXNRX control
By default the ENABLE/TXNRX pins are controlled by GPIOs, if the TDD module is enabled, the TDD FSM will take over the control of these two pins.

Lars-Peter Clausen 6862655b0d Add .gitattributes file
Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.
