dt-bindings: display: adi,adv7533: Drop single lane support

2025-01-09T12:33:51+00:00

commit ee8f9ed57a397605434caeef351bafa3ec4dfdd4 upstream. As per [1] and [2], ADV7535/7533 supports only 2-, 3-, or 4-lane. Drop unsupported 1-lane from bindings.

dt-bindings: display: bridge: tc358867: Document default DP preemphasis

2024-07-23T18:28:25+00:00

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.

dt-bindings: display: bridge: tc358775: Add support for tc358765

2024-04-23T15:28:59+00:00

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

dt-bindings: display: bridge: tc358775: Add data-lanes

2024-04-23T15:28:57+00:00

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.

dt-bindings: display: bridge: tc358775: make stby gpio optional

2024-04-23T15:28:55+00:00

For a normal operation, the stby GPIO is not needed. The reset pin is required because once the PPI (PHY protocol interface) is started, it can only be stopped by asserting the reset pin.
