Istvan Csomortani 85ffc25ec5 ad_tdd_sync: Update the synchronization logic
The synchronization interface is a single bidirectional line. Output for Master, input for Slave.
The sync_period value is relative to frame length and the digital interface clock. The actual synchronization
period will be: sync_period * frame_length * fb_clock_cycle

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.

Lars-Peter Clausen cf6052e2a8 axi_hdmi_tx: Add control to bypass chroma sub-sampler
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.

Istvan Csomortani c926daca3a ad9361/tdd: Fix generation of tx_valid_* signals
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.

Lars-Peter Clausen 41cc92ef49 Remove BASEADDR/HIGHADDR parameters
This is unused and unneeded. The AXI interconnect will make sure that a
peripheral only gets requests that are meant for it, there is no need to
check the address in the peripheral itself.

Lars-Peter Clausen 6ad589475a up_axi: Prevent read and write requests from racing against each other
Make sure that if a read and a write request arrive on the very same clock
cycle to only accept one of them. The simple solution chosen here is to only
accept the write request when this happens and delay the acceptance of the
read request until the write request is finished.

This solution is not fair since a write request will always take precedence,
which in theory allows the write bus to starve the read bus. But in practice
we should never see that many write requests that we are unable to answer
the read request.

Lars-Peter Clausen 18a506b3ca up_axi: Wait for the transaction to fully finish before releasing up_axi_access
Wait for the master to accept the response for the current transaction
before we allow a new transaction to start.

This fixes problems in case the master is not ready to accept the response
when we make it available.
