Some clocks were not documented in the released user manual, but were found in the official kernel from Allwinner. These include controls for the I2S, SPDIF, SATA, and eDP blocks. Note that on the A80, some subsystems have separate clock controllers downstream of the main clock unit. These include the MMC, USB, and display engine subsystems.

One such subsystem is the display engine. The main clock control unit now only has 1 set of bus gate, dram gate, module clock, and reset control for the entire display subsystem. These feed into a secondary clock control unit, which has controls for each individual module of the display pipeline. This block is not documented in the user manual. Allwinner's kernel was used as the reference. Add support for the display engine clock controls found on the A80.
