Regarding MIPI -DSI interfacing with TFT LCD

Question

I'm working on connecting a TFT LCD (E45RA-MW276-C) to the EK-RA8M1 board using the MIPI-DSI interface through the J58 connector . I need assistance with the specific pin muxing and configuration for this interface.

Which pins on the J58 port are muxed to the MIPI-DSI signals (Clock and Data lanes) when connecting this display?

Are there any other control signals (I2C, Reset, etc.) that need to be muxed or configured for proper operation?

Hello, 
 I assume you mean EK-RA8D1. 
 The default jumpers and switch configurations as listed on sections 4.3.3-4.3.4 are enough to use the graphics expansion board.

 On top of that the MIPI example on Github has information on how to configure the switches.

E45RA-MW276-C is the included graphics expansion board included with EK-RA8D1. You just need to connect the display on J58 ok the board. You do not need to make extra configurations on hardware. 
 These are the signals of J58:

 Then you need to add the mipi-dsi software module on FSP and enable the relevant pins. 
 Please follow the example project at github.com/.../mipi_dsi_ek_ra8d1_ep
