The MEGA Camera module is connected to SUB PCB with 24pin Board to Board connector
(AXK7L24227). Its interface is dedicated camera interface port in MSM6280. The camera port supply
24.576MHz master clock to camera module and receive 40.2MHz pixel clock (15fps), vertical sync
signal, horizontal sync signal, reset signal and 8bits data from camera module. The camera module is
controlled by I2C port from MSM6280.
