TDP158 is an AC-coupled DVI / HDMI to TMDS level shifting Redriver.
It supports DVI 1.0, HDMI 1.4b and 2.0b.
It supports 4 TMDS channels, HPD, and a DDC interface.
It supports dual power supply rails (1.1V on VDD, 3.3V on VCC)
for power reduction. Several methods of power management are
implemented to reduce overall power consumption.
It supports fixed receiver EQ gain using I2C or pin strap to
compensate for different lengths input cable or board traces.
Features
- AC-coupled TMDS or DisplayPort dual-mode physical layer input
to HDMI 2.0b TMDS physical layer output supporting up to 6Gbps
data rate, compatible with HDMI 2.0b electrical parameters
- DisplayPort dual-mode standard version 1.1
- Programmable fixed receiver equalizer up to 15.5dB
- Global or independent high speed lane control, pre-emphasis
and transmit swing, and slew rate control
- I2C or pin strap programmable
- Configurable as a DisplayPort redriver through I2C
- Full lane swap on main lanes
- Low power consumption (200 mW at 6Gbps, 8 mW in shutdown)
https://www.ti.com/lit/ds/symlink/tdp158.pdf
Like the TFP410, the TDP158 can be set up in 2 different ways:
1) hard-coding its configuration settings using pin-strapping resistors
2) placing it on an I2C bus, and defer set-up until run-time
The mode is selected via pin 8 = I2C_EN
I2C_EN high = I2C Control Mode
I2C_EN low = Pin Strap Mode
On our board, I2C_EN is pulled high.

Document default DP port preemphasis configurable via new DT property
"toshiba,pre-emphasis". This is useful in case the DP link properties
are known and starting link training from preemphasis setting of 0 dB
is not useful. The preemphasis can be set separately for both DP lanes
in range 0=0dB, 1=3.5dB, 2=6dB .
This is an endpoint property, not a port property, because the TC9595
datasheet does mention that the DP might operate in some sort of split
mode, where each DP lane is used to feed one display, so in that case
there might be two endpoints.

The tc358765 is similar to tc358775. The tc358765 just an earlier version
of the hardware, and it's pin and register compatible with tc358775 for

From the binding point of view the only difference is that the tc358765
does not have stdby-gpios.

The device uses a clock lane, and 1 to 4 DSI data lanes. Let's add the
data-lanes property starting at 1 similar to what the other bridge
bindings are doing.
Let's also drop the data-lanes properties in the example for the DSI host
controller to avoid confusion. The configuration of the DSI host depends
on the controller used and is unrelated to the bridge binding.

In the event a device is connected to the samsung-dsim
controller that doesn't support the burst-clock, the
driver is able to get the requested pixel clock from the
attached device or bridge. In these instances, the
samsung,burst-clock-frequency isn't needed, so remove
it from the required list.
The pll-clock frequency can be set by the device tree entry
for samsung,pll-clock-frequency, but in some cases, the
pll-clock may have the same clock rate as sclk_mipi clock.
If they are equal, this flag is not needed since the driver
will use the sclk_mipi rate as a fallback.

The Samsung DSIM IP block allows the inversion of the clock and
data lanes.
Add an optional property called 'lane-polarities' that describes the
polarities of the MIPI DSI clock and data lanes.
This property is useful for properly describing the hardware when the
board designer decided to switch the polarities of the MIPI DSI
clock and/or data lanes.

SPI and I2C bus node names are expected to be "spi" or "i2c",
respectively, with nothing else, a unit-address, or a '-N' index. A
pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these
cases. Mostly scripted with the following commands:
git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'
git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/'
With this, a few errors in examples were exposed and fixed.
