Mipiclock = [ (hpw+hdisp+hfp+hbp) x (vpw+vdisp+vfp+vbp) ] x(bus_hpw) x fps/ (lane_num)/2

Htotal = (hpw+hdisp+hfp+hbp) 
Vtatal = (vpw+vdisp+vfp+vbp)

pixel_clk = Htotal*Vtatal ,单位:HZ
Mipiclock = [ (hpw+hdisp+hfp+hbp)*(vpw+vdisp+vfp+vbp) ]*bus_hpw*fps/lane_num/2
          = (Htotal*Vtatal*fps)*(bus_hpw/lane_num/2)
          = pixel_clk*(bus_hpw/lane_num/2)  
这个转换公式可用于：①已知pixel_clk，计算MIPI clock；②已知MIPI clock，计算pixel_clk
举例：如果已知pixel_clk=148500000HZ，bus_hpw为24，即RGB888，lane_num为4，即有4组MIPI数据通道,则
Mipiclock = 148500000*(24/4/2) = 148500000*3 = 445500000HZ = 445.5HZ
