It takes 17ms to send each instruction (an init code consists of about 200 instructions), so it takes about 3.5s to send the init_code. So we moved the sending of the inti_code to the prepare() function, and each instruction seemed to take only 25μs. We checked the DSI host and found that the difference in command sending time is caused by the different modes of the DSI host in prepare() and enable() functions. Our DSI Host only supports sending cmd in LP mode, The prepare() function can directly send init_code (LP->cmd) in LP mode, but the enable() function is in HS mode and needs to switch to LP mode before sending init code (HS->LP->cmd->HS). Therefore, it takes longer to send the command.

Support for kd101ne3-40ti MIPI-DSI panel The K&d kd101ne3-40ti is a 10.1" WXGA TFT-LCD panel, use jd9365da controller,which fits in nicely with the existing panel-jadard-jd9365da-h3 driver.Hence,we add a new compatible with panel specific config. Although they have the same control IC, the two panels are different, and the timing will be slightly different, so we added some variables in struct jadard_panel_desc to control the timing.

It is composed of three sub blocks: * LVDS host: handles the LVDS protocol (FPD / OpenLDI) and maps its input pixels onto the data lanes of the PHY * LVDS PHY: parallelize the data and drives the LVDS data lanes * LVDS wrapper: handles top-level settings The LVDS controller driver supports the following high-level features: * FDP-Link-I and OpenLDI (v0.95) protocols * Single-Link or Dual-Link
