These are commonly seen on newer Allwinner SoCs and X-Powers ICs. Allwinner A80 SoC. The A80 contains 1 main clock control unit, and some subsystem specific clock control units at separate addresses. These include the USB, display engine, and MMC. The MMC clocks can be supported by the old clock drivers, hence here we do not add a new driver for it.
This document lists all the ARM Allwinner SoCs that are currentlysupported in mainline by the Linux kernel. This document will alsoprovide links to documentation and/or datasheet for these SoCs.

On the front of the board, the following is printed:
The PCB has the following silkscreened on it:
These markings do not have specific significance to the A83T since this is a product verification board.
Current status
There is ongoing discussion at https://groups.google.com/forum/#!topic/linux-sunxi/_woM2vJmcuc regarding the mainline support of the SoC in this board.

HW-Pack
BSP
The repository at https://github.com/allwinner-zh/bootloader contains
- BSP for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/basic_loader/bsp/bsp_for_a83
Manual build
- For building U-Boot, use the MANUFACTURER_DEVICE target.
- The .fex file can be found in sunxi-boards as MANUFACTURER_DEVICE.fex
Everything else is the same as the manual build howto.
Mainline U-Boot
For building mainline U-Boot, use the 'h8_homlet_v2_defconfig' target.
The reference source code from Allwinner is at https://github.com/allwinner-zh/bootloader contains
- Boot 0 source code for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/basic_loader/boot0
- U-boot 2011.09 for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/u-boot-2011.09
Mainline kernel
Basic support is available in mainline kernel for A83T.
Use sun8i-a83t-allwinner-h8homlet-v2.dtb device-tree tree binary.
There is a 3.4 source tree for the A83T at https://github.com/allwinner-zh/linux-3.4-sunxi/tree/A83T
The following table is a comparison of the A83T SoC to other SoCs from the A-series.
| Module | Description |
|---|---|
| CPU | Cortex-A7 MP4 in 2 clusters, the MCPM is more likely as the A80 |
| CCI400 | It's same as the A80 |
| DRAMM | It's more likely as the A80 |
| Timer | It's same as the A31 and A20 |
| CCU | It's more likely as the A80 |
| DMA | It's same as the A31 |
| PinCtrl | It's same as the A31 |
| UART | It's same as the A31 and A20 |
| RSB | It's same as the A80 and A33 |
| SPI | It's same as the A31 and A20 |
| TWI | It's same as the A31 and A20 |
| NAND | It's more likely as the A80 and A33, but the clk/dma/pin are different |
| SD/eMMC | It's same as the A31 and A20 |
| USB2.0 OTG | It's same as the A31 and A20 |
| USB HCI | It's same as the A31 and A20 |
