Hi,

This is a new DRM driver for Texas Instruments' Keystone K2G SoC. K2G has DSS6
IP, which is related to the OMAP DSS IPs handled by the omapdrm driver. While
on higher level the DSS6 resembles the older DSS versions, the registers and
the internal pipelines differ a lot.

DSS6 IP on K2G is a "ultra-light" version, and has only a single plane and a
single output. The driver will also support future DSS versions, like DSS7 on
AM6 SoC, which supports multiple planes and outputs, so the driver already has
support for those. This is also the reason for the dispc abstraction layer.

The series is an RFC, as I want to include the DSS7 driver in the final
version. I hope that's ready in a week or two. I'm looking for comments on the
overall architecture.

 Tomi

Aand I forgot to give credit to Laurent, as I did look at his rcar-du
driver a lot when writing this. There's also a lot of code adapted from
omapdrm.
