Paulo Zanoni 8a1874559f drm/i915: add initial Runtime PM functions ... This patch adds the initial infrastructure to allow a Runtime PM implementation that sets the device to its D3 state. The patch just adds the necessary callbacks and the initial infrastructure. We still don't have any platform that actually uses this infrastructure, we still don't call get/put in all the places we need to, and we don't have any function to save/restore the state of the registers. This is not a problem since no platform uses the code added by this patch. We have a few people simultaneously working on runtime PM, so this initial code could help everybody make their plans. V2: - Move some functions to intel_pm.c - Remove useless pm_runtime_allow() call at init - Remove useless pm_runtime_mark_last_busy() call at get - Use pm_runtime_get_sync() instead of 2 calls - Add a WARN to check if we're really awake V3: - Rebase. V4: - Don't need to call pci_{save,restore}_state and pci_set_power_sate, since they're already called by the PCI layer - Remove wrong pm_runtime_enable() call at init_runtime_pm Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2013-12-10 22:43:14 +01:00
