Hi!
I am working on a custom board design based on STM32MP157FAA1.
I need to interface a MIPI display with the microprocessor.
I am powering this microprocessor using STPMIC1APQR PMIC. As per the datasheet of the PMIC, the default output voltage from BUCK3 will be 3.3V and this powers VDD_DSI (Pin A14) and I am also aware that the microprocessor internally generates 1.2V for DSI section.
Now the MIPI display I'll be using utilizes EK79007 LCD driver IC. The recommended VDD for EK79007 is 1.8V. I want to know if this display can be interfaced with the MIPI section of STM32MP157FAA1.
I have added the data sheet of the display and also the LCD driver for your reference.
Thanks & Regards,
Cleatus Wesley
