The A523 PPU is likely the same kind of hardware seen on previous SoCs.
|
|
|
|
The A523 PCK600, as the name suggests, is likely a customized version
|
|
of ARM's PCK-600 power controller. Comparing the BSP driver against
|
|
ARM's PPU datasheet shows that the basic registers line up, but
|
|
Allwinner's hardware has some additional delay controls in the reserved
|
|
register range. As such it is likely not fully compatible with the
|
|
standard ARM version.
|
|
|
|
Document A523 PPU and PCK600 compatibles.
