MTK 调试记录

MT8788/MT8183 使用CC1 CC2做OTG检测：
#CONFIG_MTK_USB_TYPEC_U3_MUX         //关闭

//打开一下宏
CONFIG_TCPC_CLASS=y
CONFIG_TCPC_MT6370=y
CONFIG_MTK_USB_TYPEC=y
CONFIG_USB_POWER_DELIVERY=y

GPS:
配置GPS定位伽利略等配置：
vendor/mediatek/proprietary/hardware/connectivity/gps/mtk_mnld/mnld_entity/src/gps_controller.c

LCM：
        MTK平台旋转90度，开机logo下部分显示不全。显示黑条。
 解决：
​​​​​​​        修改vendor\mediatek\proprietary\bootable\bootloader\lk\lib\libshowlogo和vendor\mediatek\proprietary\external\libshowlogo 两个目录下的show_logo_common.c文件。
