Initial version of this driver. The full datasheets are available from the Analog Devices website: http://ez.analog.com/docs/DOC-1741 Not all features of the receiver are supported by this driver for various reasons. Most notably: - No CEC support (the CEC API needs a lot more discussion) - No HDCP repeater support (we don't use that either) I'm sure that there are more things missing, but this driver does work well for our hardware. Note that I am using the register addresses instead of register names: the datasheet containing the register descriptions is organized by register address. Using names would make the datasheet lookup very hard. An attempt was made to try and document what is being done when registers are used instead.
