高通Camera点亮2——Sensor点亮

高通Camera的点亮可以参考说明文档《80-P9301-97_REV_Y_Camera_Sensor_Driver_Bringup_Guide.pdf》，但是实际发现其中有些内容不够详细，因此这里进行重新补充，也作为自己知识的整理。

Sensor配置获取

要想点亮Sensor，需要向Sensor厂商获取Sensor的配置，一般需要确认：

输出分辨率与帧率
输入时钟(MCLK)：一般情况Sensor的输入时钟是ISP提供，需要确认ISP支持那些时钟输出；一般是可以配置的，保险起见最好选择像24M这样的标准时钟。
输出格式：RAW/RGB/YUV
宽动态模式：线性/build-in/DCG/HDR
数据输出方式：MIPI/LVDS
Lane数量：1/2/4
输出最大传输速率限制：Sensor接不同的serders或者ISP芯片对最大传输速率限制各不相同；
RAW图的位数(8/10/12/14/16)：线性模式下主要限制是传输；而宽动态模式下位数的限制主要是后端ISP能支持几位的数据处理，尤其是Sensor build-in模式下2帧合成和4帧合成输出ISP解压缩模块要求完全不同；
是否binning：高分辨率用作低分辨率时会用到binning，比如将800W像素，每2*2个像素合成一个；
镜像/翻转；
画面位置及裁剪，根据实际需求不同提需求；
该配置是否在其他平台上对接过？如果确定某配置是出图正常的，会让对接过程顺利不少；
如果有多个配置需求可以一起提出来，能节省时间。

Sensor XML配置

Sensor Clock 说明

Sensor点亮相关的有3个Clock：Input Clock、Pixel Clock和MIPI Data Clock。
Sensor Input Clock就是上面Sensor XML中的MCLK，一般的CMOS Sensor都不带晶振，时钟源是由其他芯片提供的，上面配置的是24M，也是最常见的时钟。
Pixel Clock是上面配置中的outputPixelClock，它表示的含义是：1秒钟内这颗Sensor能打点的总个数。
这里把Sensor输出的一个个pixel当成在纸片上打点一样来看，目前这颗Sensor（ov13b10）输出实际分辨率4208x3120分辨率，即打了3120行，每行4208个实际输出点。聪明人一算4208x3120x30=394M跟上面配置的451M不一样呀。因为Pixel Clock的含义其实是时间，这里只算了实际输出点的时间，没有算打点的针头从一行结束的末尾移动到下一行开头的时间，也没有算打点的针头从画面末尾移动到画面开头的时间。这里没有算的2个时间，前者叫行消隐，后者叫列消隐。
总行长（lineLengthPixelClock） = image width + 行消隐；
总列长（frameLengthLines）= image height + 列消隐；
Pixel Clock的公式：

Pixel Clock = lineLengthPixelClock  *   frameLengthLines  *  fps

lineLengthPixelClock在Sony 的Sensor中一般称为LINE_LENGTH_PCK，而在OV的Sensor中一般称为HTS；frameLengthLines在Sony 的Sensor中一般称为FRAME_LENGTH_LINES，而在OV的Sensor中一般称为VTS。而APP需要一个更低的Sensor帧率而分辨率不变，也是直接通过上面的公式更改frameLengthLines 来更改帧率的。你可以想象一下，要想帧率低，让一帧结束到下一帧开始之间的时间变成长一些就可以做到。
这里还有一个点说明：有些Sensor是支持lineLengthPixelClock是支持多倍的，尤其是lineLengthPixelClock配置比输出分辨率的行长还要小的时候。比如这里的ov13b10，HTS的实际配置为0x0498(1176)，比实际输出的4208还要小，但是实际的lineLengthPixelClock为1176*4=4704，这部分可以跟Sensor厂商确认。

Sensor CPP

Sensor CPP中定义了Sensor曝光时间和增益变化相关的设置，
这里需要注意：

最大增益和最小增益；
生效增益的顺序：一般是先AG后DG；
增益单位；
这些需要参考Sensor的Datasheet和Gain table一起确认。
