MCLK和PCLK的区别与联系

PCLK:pixel clock, used for MCU camera sensor controller to capture
each pixel.
MCLK:master clock for sensor logical chip.
HSYNC and VSYNC used for MCU camera sensor controller to capture the pixels line by line and frame by frame. They work just like the LCD reversely.

mclk由BB提供，是CCM sensor的时钟源。

mclk经过sensor处理后变成传输数据所需要的时钟PCLK，将数据传到BB端
