【海思篇】【Hi3516DV300】十八、TSENSOR 芯片温度检测驱动 开发

一 芯片操作步骤

参考<<Hi3516DV300专业型Smart IP Camera SoC用户指南.pdf>>的3.10.5.2 芯片内部温度检测

芯片内部集成温度传感器(T-Sensor)，温度的检测范围为-40~125℃。使能温度传感器数
据采集的流程如下：
T-sensor 相关的寄存器为 MISC 寄存器 MISC_CTRL45~MISC_CTRL50。
步骤 1 设置 T-Sensor 采集模式 MISC_CTRL45[30]。
步骤 2 如果设置为循环采集模式，需设置循环采集周期 MISC_CTRL45[27:20]；如果设置为单次采集模式，可略过此步骤。
循环采集周期计算公式为：
T = N × 2 (ms)
其中 N=MISC_CTRL45[27:20]。
步骤 3 使能 T-Sensor MISC_CTRL45[31]，开始温度采集。
步骤 4 软件读取 T-Sensor 采集到的温度码（十六进制值）。
单次采集模式下，只有 MISC_CTRL47[9:0]中记录的温度记录码 0 有效。
循环采集模式下，MISC_CTRL47[31:0]~MISC_CTRL50[31:0]记录了最近八次温度记录码 0~7，其中最新的温度记录值为温度记录码 0。
步骤 5 根据温度记录码计算出对应的温度值。
Temperature = (tsensor_result − 136)/793 × 165 − 40(℃)

注：tsensor_result 是步骤 4 中获取的温度记录码的十进制值。

二 驱动层实现

主要实现通过寄存器读写实现基本功能和文件设备操作的ioctl
