With this, user can run perf trace without libaudit on powerpc

This patchset add initial support for Allwinner V3s CSI.
Allwinner V3s SoC features two CSI module. CSI0 is used for MIPI CSI-2
interface and CSI1 is used for parallel interface. This is not

Allwinner V3s SoC features two CSI module. CSI0 is used for MIPI CSI-2
interface and CSI1 is used for parallel interface. This is not

This patch implement a v4l2 framework driver for it.
Currently, the driver only support the parallel interface. MIPI
