According to the V4L2 API, the VIDIOC_STREAMON ioctl should return EPIPE
if there is a format mismatch in the pipeline configuration.
As the .vidioc_streamon in the v4l2_ioctl_ops usually forwards the error
caused by the v4l2_subdev_link_validate_default (if it is in use), it
should return -EPIPE

It looked to do everything SPI does which is everything I know about.

sg_alloc_table_from_buf() provides an easy solution to create an sg_table
from a virtual address pointer. This function takes care of dealing with
vmallocated buffers, buffer alignment, or DMA engine limitations (maximum
DMA transfer size).

Hello,
This patch series aims at adding support for DMA assisted operations to
the sunxi_nand driver.
The first 3 patches are just reworks in the existing driver preparing
things for DMA ->read/write_page() operations. Those ones are mainly
re-arranging existing functions, and moving some code in
Some NAND controller drivers are making use of DMA to transfer data from
the controller to the buffer passed by the MTD user.
Provide a generic mtd_map/unmap_buf() implementation to avoid open coded
(and sometime erroneous) implementations.

The sunxi NAND controller is able to pipeline ECC operations only when
operated in DMA mode, which improves a lot NAND throughput while keeping
CPU usage low.

Allow for NULL cur_offs values when the caller does not know where the
NAND page register pointer point to.

sunxi_nfc_hw_ecc_read_chunk() always retrieves the ECC and protected free
bytes, no matter if the user really asked for it or not. This can take a
non negligible amount of time, especially on NAND chips exposing large OOB
areas (> 1KB). Make it optional.

In order to support DMA operations in a clean way we need to extract some
of the logic coded in sunxi_nfc_hw_ecc_read/write_page() into their own
function.
