In overwrite mode, start will be set to head in perf_mmap__read_init.
Therefore, it is no need to set the start one more in

Enable the undefined length INCR burst type and set INCRx.
Different platform may has the different burst size type.
In order to get best performance, we need to tune the burst size to
one special value, instead of the default value.

The magn_3d_channels array has multiple declarations of iio_chan_spec.
Most of the iio_chan_spec are very similar, changing only by the .type
and .channel2 field. This patch reduces the code duplication by adding a
macro that can replace the iio_chan_spec repetitions in the
magn_3d_channels array.

It would be handy to do this. I *think* you can do it on normal
hardware, even if it does not have "real" support for memory encryption.
Just don't set the encryption bits in the PTEs but g

The Allwinner SoCs usually come with a DSI encoder. Add a binding for it.

The BananaPi M2M has an optional 1280x720 DSI panel. Since that panel is
optional, we can only show a DT patch that would show how to enable it.

Most of the Allwinner SoCs since the A31 share the same MIPI-DSI
controller.
While that controller is mostly undocumented, the code is out there and has
been cleaned up in order to be integrated into DRM. However, there's still
some dark areas that are a bit unclear about how

The "CPU" (or Intel 8080) interface uses a different interrupt called
TRI_FINISH (most likely TRI being for trigger) to notify the end of frames,
and hence the VBLANK period.
And that interrupt to the possible VBLANK interrupts source.

Hi,
Here is an preliminary version of the MIPI-DSI support for the Allwinner
SoCs.
This controller can be found on a number of recent SoCs, such as the
A31, A33 or the A64.
Given the sparse documentation, there's a number of obscure areas, but
the current implementation has been tested with a 4-
