      MLK-19157 imx8mm_evk: Disable dsi panel before booting kernel · 4d436d59
      Ye Li authored
      
      
      Pull down the DSI_EN gpio to disable mipi dsi panel before booting kernel.
      This avoids display full yellow screen before kernel mipi driver probes
      the device.
      
      For MIPI2HDMI card, this DSI_EN gpio is not used. So nothing impact to it.

      MLK-18945-10 imx8mm_evk: Add splash screen support for MIPI DSI · 41f896ce
      Ye Li authored
      
      
      Add board level codes for enabling splash screen on imx8mm EVK. We
      support two different display connecting to MIPI DSI miniSAS interfaces:
      
      1. MIPI2HDMI daughter card (default)
      2. RM67191 OLED panel
      
      Users can set "panel" env vairable to "MIPI2HDMI" or "RM67191_OLED" to
      switch them after reboot.

      Enable the USB host and device support, add relvent board level codes
      and settings.
      
      For device mode, the gadget is fixed on USB device 0. Can't support
      gadget on USB device 1.

      MLK-18289-2 imx8mm_evk: Add codes to setup typec PD charging · e3579303
      Ye Li authored
      
      
      On iMX8MM EVK, the USB2 port is the primary power supply, when USB2 is charging,
      the 3483_EN_SNK1 is not enabled. In the board, we init the tcpc of USB2 first with
      PD enabled. If it is charging, when init the tcpc of USB1 we disable the PD,
      otherwise we enable PD on USB1.
      
      The USB PD switch NX20P3438 needs to exit dead battery mode before
      enable EN_SINK, otherwise the OVP is fixed at 6.8V. Also the OVP threshold needs set to
      23V, when we switch to use 20V VBUS input.
      
      Due to HW issue, after we switched to 9V/20V, set on/off button to off then set back it to
      on, the board can't power up. In this patch we limit the voltage to 5V, will change back
      to 9V/20V when HW fixes the issue.
