This patchset tries to add support for Allwinner V3/S3L and Sochip S3. Allwinner V3/V3s/S3L and Sochip S3 share the same die, but with different package. V3 is BGA w/o co-packaged DDR, V3s is QFP w/ DDR2, S3L is BGA w/ DDR2 and S3 is BGA w/ DDR3. (S3 and S3L is compatible for pinout, but because of different DDR, DDR voltage is different between the two variants). Because of the pin count of V3s is restricted due to the package, some pins are not bound on V3s, but they're bound on V3/S3/S3L.
Currently the kernel is only prepared for the features available on V3s. This patchset adds the features missing on V3s for using them on V3/S3/S3L, and add bindings for V3/S3/S3L. It also adds a S3 SoM by Sipeed, called Lichee Zero Plus.
