Message-Id: <1398179373-29966-1-git-send-email-thierry.reding@gmail.com> Date: Tue, 22 Apr 2014 17:09:28 +0200 From: Thierry Reding <thierry.reding@...il.com> To: dri-devel@...ts.freedesktop.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Russell King <rmk+kernel@....linux.org.uk>, linux-kernel@...r.kernel.org, linux-tegra@...r.kernel.org Subject: [RFC 0/5] drm/tegra: Convert to master/component framework From: Thierry Reding <treding@...dia.com> 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. Patches 1 and 2 make some changes to the master/component framework which are necessary to convert Tegra DRM to use it. Note that since I'm looking for early review I haven't converted any of the existing users since I'm not sure if these are acceptable changes. Patch 3 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. A new function is introduced in patch 4 which can be used to get rid of the DRM bus infrastructure in individual drivers. It should be able to replace the requirement of having a drm_bus for all USB and platform DRM drivers. For backwards-compatibility with legacy PCI drivers some- thing different will probably be needed. Finally, patch 5 converts the Tegra DRM driver over to using the master/ component framework using the above four patches. 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 with Daniel's DRM cleanup series applied. I welcome any questions or comments you might have.
