Those were added by mistake. It does not seem to be legal Verilog, but for
some reason Vivado accepts it.

ffff and 0000 are always reserved control characters when using embedded
syncs. So make sure that we never have them in the pixel data, even when
running in full-range mode.

Add a control bit to the register map that allows to bypass the chroma
sub-sampler in the axi_hdmi_tx core. This is primarily interned to be used
to send the test-pattern directly to the HDMI transmitter without modifying
it.

Currently the hdmi_de_int signal is asserted one clock cycle too early in
packed 422 mode. As a result the EAV sequence ends up in the first pixel
and every other pixel is off by one.

Check for both full range and limited range test-pattern sequences and only
if both don't match assert the tpm_oos signal.

Move the test pattern matcher to its own module. This makes it easier to
use it in other configurations as well.

The TPG is no longer part of the RX core and the corresponding bit in the
register map isn't hooked up to anything. So drop it.

The TPM OOS status flag is in bit 1. Make sure writing to bit 1 rather than
bit 0 clears the TPM OOS.

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.

- removed up_drp_control, up_delay_control dependencies where not needed
- added axi_jesd_gt core in the library makefile
- fixed timing tcl dependency for altera projects
Some cases, when software changed the image formats, the packed formats (24bit/pixel) lost alignment.
(the first 32 bit after sof got lost) This commit fix that issue.
In FDD mode the tx_valid_* signals are generated inside the axi_ad9361_tx module, in function of
the selected dac data rate. In TDD mode, these signals are gated by the tdd_enable and tdd_tx_dp_en signals.
In other words, the tx_valid_* signals will be valid just when tdd_enable and tdd_tx_dp_en is active.
This core has been superseded by the SPI Engine framework in combination
with the axi_generic_adc core.

The util_sigma_delta_spi peripheral can be used to seperate the interleaved

SPI Engine is a highly flexible and powerful SPI controller framework. It
consist out of multiple sub-modules which communicate over well defined
interfaces. This allows a high degree of flexibility and re-usability while
at the same time staying highly customizable and easily extensible.
Currently included are four components:
* SPI Engine execution module: The excution module is responsible for
handling the low-level physical interface SPI logic.
* SPI Engine AXI interface module: The AXI interface module allows
memory mapped acccess to a SPI bus control stream and can be used to
implement a software driver that controls the SPI bus.
* SPI Engine offload module: The offload module allows to store a
predefined SPI Engine command and data stream which will be send out
when a external trigger signal is asserted.
* SPI Engine interconnect module: The interconnect module allows to
combine multiple control streams into a single stream giving multiple
control modules access to a execution module.

The axi_generic_adc core is a simple core that doesn't do much more then
implementing the AXI ADC register map and routing the enable and overflow
signals to the farbic.

The cordic_demod module takes in phase and data on s_axis interface then
performs a cordic demodulation and outputs the resulting I and Q component
data on the m_axis interface.

Allow to specify the direction of the reset signal for a interface, this is
useful if the core itself generates the reset signal.
