Subject: [PATCHv5,RESEND 0/8] Support for Tegra 2D hardware
This set of patches adds support for Tegra20 and Tegra30 host1x and
2D. It is based on linux-next-20130114. The set was regenerated with
git format-patch -M.
The fifth version merges DRM and host1x drivers into one driver. This
allowed moving include/linux/host1x.h back into the driver and removed
the need for a dummy platform device. This version also uses the code
from tegradrm driver almost as is, so there are a lot less actual code
changes.
This patch set does not have the host1x allocator, but it uses CMA
helpers for memory management.
host1x is the driver that controls host1x hardware. It supports
host1x command channels, synchronization, and memory management. It
is sectioned into logical driver under drivers/gpu/host1x and
physical driver under drivers/host1x/hw. The physical driver is
compiled with the hardware headers of the particular host1x version.
The hardware units are described (briefly) in the Tegra2 TRM. Wiki
page https://gitorious.org/linux-tegra-drm/pages/Host1xIntroduction
also contains a short description of the functionality.
The patch set merges tegradrm into host1x and adds 2D driver, which
uses host1x channels and sync points. The patch set also adds user
space API to tegradrm for accessing host1x and 2D.
