https://review.coreboot.org/c/coreboot/+/73443/comment/7f6665b5_9d4c5d4a PS1, Line 9: For Geralt,it is necessary to increase the AVDD/AVEE of : TPS65132S PMIC to +-5.7V,so write the default value in : eeprom to +-5.7V when configure display for the first : time. In this way,the default voltage is +-5.7V when you : start or enter the kernel next time. It is necessary to increase the AVDD/AVEE of TPS65132s PMIC to +-5.7V for powering on BOE_TV110C9M_LL0. So we set the default value to +-5.7V and program the value to the EEPROM when configuring the display at the first time. In this way, TPS65132s could load the correct setting from the EEPROM after booting into kenrel.
