clk: sunxi-ng: Add driver for A83T CCU The A83T clock control unit is a hybrid of some new style clock designs from the A80, and old style layout from the other Allwinner SoCs. Like the A80, the SoC does not have a low speed 32.768 kHz oscillator. Unlike the A80, there is no clock input either. The only low speed clock available is the internal oscillator which runs at around 16 MHz, divided by 512, yielding a low speed clock around 31.250 kHz. Also, the MMC2 module clock supports switching to a "new timing" mode. This mode divides the clock output by half, and disables the CCU based clock delays. The MMC controller must be configure to the same mode, and then use its internal clock delays. This driver does not support runtime switching of the timing modes. Instead, the new timing mode is enforced at probe time. Consumers can check which mode is active by trying to get the current phase delay of the MMC2 phase clocks, which will return -ENOTSUPP if the new timing mode is active.

clk: sunxi-ng: Add A80 CCU Add support for the main clock unit found in the A80. 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.

clk: sunxi-ng: Add fractional lib Some clocks can be switched to a mode called fractional that have two fixed output rate you can choose from. Add a small library to deal with those clocks.
