Hi Abhinav, Thanks for posting this driver. Some comments below. On Saturday 07 April 2018 12:36 PM, Abhinav Kumar wrote:

The compatible string, kernel config and the driver file should be based on the panel model no. There can be many truly based panels that support wqxga. Something like "truly,nt35597" would be better.
+- vdda-supply: phandle of the regulator that provides the supply voltage + Power IC supply +- lab-supply: phandle of the regulator that provides the supply voltage + for LCD bias +- ibb-supply: phandle of the regulator that provides the supply voltage + for LCD bias
Both seem to have the same description. Aren't lab and ibb qualcomm specific terms? Could we use the pin names specified in the panel's data sheet?
+- reset-gpios: phandle of gpio for reset line + This should be 8mA, gpio can be configured using mux, pinctrl, pinctrl-names +- mode-gpios: phandle of the gpio for choosing the mode of the display + for single DSI or Dual DSI
Could we describe here how to use this gpio? I.e, whether we need to set it to low for dual DSI, etc?
+- display-timings: Node for the Panel timings +- link2: phandle to the secondary node of the panel
The link2 binding was a temporary hack we used. We should use the of-graph bindings to represent the two DSI input ports of the panel.

We can drop the commented lines. If possible, it would be nice to have some more description about the registers, but I can imagine that info being hard to retrieve.

This should go when we use the of-graph bindings. The second mipi_dsi_device needs to be created manually in the driver using mipi_dsi_device_register_full(). You could look at the ADV7511 bridge driver as an example. We would eventually need to call mipi_dsi_attach() on the second device too. Thanks, Archit
