Automotive Linux Summit & Open Source Summit Japan 2018

Automotive rear seat infotainment, camera monitoring and digital media receivers involve multimedia data transmission among application processor, sensors and display panels; to reduce cost and simplify electronic design of ADAS and infotainment systems high speed serial link solutions like TI FPD-Link III or Maxim GMSL are commonly used. Serializers and deserializers (SerDes) are sophisticated ICs, which allow to bridge both multimedia data streams and control signals like GPIO, I2C or UART. Linux DRM framework supports video data bridges, but there is no complete abstractions for configurable bypass channels between ICs in Linux GPIO or I2C frameworks. Vladimir Zapolskiy will present advanced Linux device drivers and device tree description of SerDes ICs in preparation to submit the changes upstream.
