This series adds CEC drivers for the dw-hdmi and TDA9950 devices.
dw-hdmi integrates a CEC engine in the same device as the video and audio blocks, and so shares the IO space and IRQ with the main video driver.
The TDA9950 is not only a separate CEC device in its own right, but can also be found on the TDA998x family of HDMI encoders as a separate I2C device from the main TDA998x device.
The drivers are placed along-side their HDMI encoder drivers to keep the code for these drivers nearby. However, if there's a better location (eg, a CEC drivers subdirectory) then that would probably be a better location for these.
Both sets of drivers rely on the hdmi-notifier code, hence why they're part of the same patch series.
