[media] adv7604: driver for the Analog Devices ADV7604 video decoder
Initial version of this driver. The full datasheets are available from the Analog Devices website: http://ez.analog.com/docs/DOC-1545 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) - Only port A of the four HDMI input ports is implemented (our hardware only uses that port) - No HDCP repeater support (we don't use that either) And since there are some 600-odd pages of datasheet for this single device, I'm sure that there are many 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.
