From: Thierry Reding <treding@xxxxxxxxxx> Hi, This series converts the Tegra DRM driver to the master/component framework. The length of the series and the list of people in Cc is mostly due to the fact that Tegra has some special requirements as opposed to other drivers and therefore requires some changes outside of DRM. Patch 1 introduces a helper function that can be used by new DRM drivers that don't rely on legacy userspace ABIs. It allows them to register DRM devices much more easily and without much of the midlayer that currently exists in the DRM subsystem. Patches 2 and 3 make some changes to the master/component framework which are necessary to convert Tegra DRM to use it. All current users of the API have been converted as part of this patch. Note that at the same time the drivers are converted to no longer use drm_platform_init() in favour of the drm_set_unique() from patch 1 in conjunction with drm_dev_alloc() and drm_dev_register(). I would've liked to avoid such invasive changes in a single patch, but unfortunately I couldn't think of a way how to do that. I'm open to suggestions. Patch 4 adds a new interface framework that supplements the master/ component framework and can be used in situations where there is no struct device * that a driver can bind to. The Tegra DRM driver is converted to using the master/component framework in patch 5 using the above four patches. Finally patches 6 and 7 add some documentation about the new way of registering DRM devices that don't need legacy support. Each patch has a somewhat more elaborate description of why it is needed or what problem it solves. The patchset applies on top of linux-next. I welcome any questions or comments you might have.
