[PATCH v3 0/3] drm/nouveau: support for probing platform devices
This series adds support for probing platform devices on Nouveau, as well as
the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since
a few extra things need to be supported before that.
This version is mostly identical to v2 but fixes an important issue: the drvdata
must be set to the drm_device for sysfs to work, so the platform device
structure now includes the

[PATCH v2 0/3] drm/nouveau: support for probing platform devices
This series adds support for probing platform devices on Nouveau, as well as
the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since
a few extra things need to be supported before that.
Thanks to the input received for v1, this version is more self-contained and
shares less stuff between nouveau_drm and nouveau_platform. The major change
is that nouveau_platform is now

[PATCH 00/15] Support for GP10B chipset
GP10B is the chip used in Tegra X2 SoCs. This patchset adds support for
its base engines after reworking secboot a bit to accomodate its calling
convention better.
This patchset has been tested rendering simple off-screen buffers using Mesa
and yielded the expected result.
Alexandre Courbot (15):
secboot: allow to boot multiple falcons
secboot: pass instance to LS firmware loaders
secboot:
