高通挂载bp侧驱动bringup流程
BP侧修改
(1)添加供应商给的驱动
添加到vendor\qcom\non-hlos\ADSP.VT.5.4.3.c1\adsp_proc\ssc_drivers
(2)添加编译
\vendor\qcom\non-hlos\ADSP.VT.5.4.3.c1\adsp_proc\ssc\chipset\divar\por.py
if 'SSC_TARGET_X86' not in env['CPPDEFINES']:
#POR sensors list
include_sensor_vendor_libs.extend(['lsm6dso', #ACCEL/GYRO/MD/TEMP
'sns_ak0991x', #MAGNETOMETER
'sns_tmd2725', #ALS/PROX
'sns_bmp285', #PRESSURE
'sns_bu52053nvx', #HALL
'sns_sc7a20',
'sns_ltr569'])
/*此处id为供应商给的驱动文件中LTR-569ALS-WA\build\sns_ltr569.scons，.scons的前缀*/
(3)修改通讯协议
-3.1vendor\qcom\
non-hlos\ADSP.VT.5.4.3.c1\adsp_proc\core\settings\buses\qup_fw\config\divar\fw_devcfg.c
根据DATA SHEET选择对应SE设备修改通信协议
-3.2vendor\qcom\non-hlos\
ADSP.VT.5.4.3.c1\adsp_proc\core\settings\buses\i2c\config\divar\i2c_devcfg.c
(4)查看是否编译成功：
1.编译成功会adsp_proc下生成obj文件夹，里面有所有的镜像
2.或在驱动文件的build下生成/sensor.img/所有.o文件
可以直接在编译目录下$:find -name "xxxx.o"以快捷搜索有无.o生成
AP侧修改
添加.json文件在

将sensor器件添加到高通island（低功耗模式）
【不同平台特性不同，此操作需和平台确认清楚能不能去掉！并非所有平台都能去掉这三行！】
vendor\qcom\non-hlos\ADSP.VT.5.4.3.c1\adsp_proc\ssc\chipset\divar\por.py
(1)先在在此文件中注释掉以下三行，以释放island空间来添加新器件进island空间：
#env.AddUsesFlags(['SNS_DYNLIB_LOCAL_HEAPMGR'])
#env.AddUsesFlags(['SNS_DYNLIB_LSM6DSO'])
#env.Append(CPPDEFINES = ['SNS_DYNLIB_NUM_OF_ISLAND_PAGES = 11'])
(2) 在此处添加驱动名
# 1. Island drivers
env.AddUsesFlags(['SNS_ISLAND_INCLUDE_HX32062SE'])
#env.AddUsesFlags(['SNS_ISLAND_INCLUDE_AK0991X'])
#env.AddUsesFlags(['SNS_ISLAND_INCLUDE_TMD2725'])
#env.AddUsesFlags(['SNS_ISLAND_INCLUDE_BMP285'])
island驱动名获取方法:打开驱动文件中的build文件(后缀.scons)，找到以下句段，
if 'SNS_ISLAND_INCLUDE_HX32062SE' in env:
hx32062se_island_enable = True
其中引号中的id就是添加到por.py的id。
