Arto Merilainen ebae30b1fb gpu: host1x: Rework CPU syncpoint increment
This patch merges host1x_syncpt_cpu_incr to host1x_syncpt_incr() as
they are in practise doing the same thing. host1x_syncpt_incr() is
also modified to return error codes. User space interface is modified
accordingly to pass return values.

Arto Merilainen ece66891ff gpu: host1x: Fix client_managed type
client_managed field in syncpoint structure was defined as an
integer. The field holds, however, only a boolean value. This patch
modifies the type to boolean.

Thierry Reding ed683aead1 drm/tegra: Honor pixel-format changes
When using a base mode-set, honor changes in pixel-format since the core
doesn't explicitly check for them as long as they use the same depth.

Thierry Reding 603f0cc948 drm/tegra: Explicitly set irq_enabled
Since the Tegra DRM driver doesn't use the drm_irq_install() helper, the
irq_enabled flag needs to be set manually in order to make functionality
such as the DRM_IOCTL_WAIT_VBLANK work properly.

DC registers aren't available for programming.

Arto Merilainen de2ba664c3 gpu: host1x: drm: Add memory manager and fb
This patch introduces a memory manager for tegra drm and moves
existing parts to use it. As cma framebuffer helpers can no more
be used, this patch adds also a separate framebuffer driver for
tegra.
