This series adds runtime pm support for host1x, gr2d and dc. It retains the current behaviour if CONFIG_PM_RUNTIME is not enabled. The gr2d clock is enabled when a new job is submitted and disabled when the work is done. Due to parent->child relations between host1x->gr2d, this scheme enables and disables host1x clock. For dc, the clocks are enabled in .probe and disabled in .remove via runtime pm instead of direct clock APIs. Mayuresh is unfortunately not available to continue with the series and hence I will continue working on the patches. Changes in v3: - Rebased patches on top of 3.12-rc2 - Removed unnecessary #ifdefs - Added descriptions to commit messages - If runtime pm is disabled, the code calls suspend/resume functions for enabling/disabling the clocks instead of repeating the functions Mayuresh Kulkarni (4): gpu: host1x: shuffle job APIs drm/tegra: Add runtime pm support for gr2d drm/tegra: Add runtime pm support for dc gpu: host1x: Add runtime pm support for host1x drivers/gpu/host1x/cdma.c | 2 ++ drivers/gpu/host1x/channel.c | 8 ------ drivers/gpu/host1x/channel.h | 1 - drivers/gpu/host1x/dev.c | 57 +++++++++++++++++++++++++++++++++++++++--- drivers/gpu/host1x/drm/dc.c | 58 +++++++++++++++++++++++++++++++++++++++---- drivers/gpu/host1x/drm/gr2d.c | 57 ++++++++++++++++++++++++++++++++++++++---- drivers/gpu/host1x/job.c | 13 ++++++++++ drivers/gpu/host1x/job.h | 3 +++ 8 files changed, 176 insertions(+), 23 deletions(-) -- 1.8.1.5 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
