Date: Tue, 20 Jan 2015 11:48:19 +0100 From: Thierry Reding <thierry.reding@...il.com> To: dri-devel@...ts.freedesktop.org Cc: linux-tegra@...r.kernel.org, linux-kernel@...r.kernel.org, Russell King <linux@....linux.org.uk>, Mike Turquette <mturquette@...aro.org>, Stephen Boyd <sboyd@...eaurora.org> Subject: [PATCH 00/36] drm/tegra: Atomic mode-setting conversion From: Thierry Reding <treding@...dia.com> This series converts the Tegra DRM driver to atomic mode-setting. The size of the is somewhat misleading, because a bunch of preparatory work is included. The first patch adds a new function to the clk API that allows checking that setting a parent clock can succeed. This is needed to make sure an atomic state can be applied before actually making any changes to the hardware. Patch 2 makes the plane's ->atomic_update() callback mandatory because there is no use-case in which it makes sense to omit it. Patches 3 and 4 add additional callbacks for planes and encoders, which are needed by subsequent patches. Patch 5 adds a helper to obtain the state of the CRTC that a plane is being attached to. This is non-trivial, so a new helper is warranted. Patches 6 to 21 are preparatory work and cleanup needed to simplify the atomic mode-setting transition. Patches 22 to 32 are the actual conversion to atomic mode-setting. This is followed-up by patch 33 removing now unused code. Patches 34 and 35 use the ->atomic_check() callbacks to store data that can be reused at the commit stage to avoid having to recompute it. Finally patch 36 can now move some duplicate code from the output drivers to the display controller.
