Subject: [PATCH v3 12/15] clk: sunxi-ng: a523: remaining mod clocks
Add the remaining mod clocks, driving various parts of the SoC: the "LEDC"
LED controller, the "CSI" camera interface, the "ISP" image processor,
the DSP clock, and the "fanout" clocks, which allow to put clock signals
on external pins.
