* drivers: gpu: Mark function as static in r600_hdmi.cRashika Kheria2014-01-07

* drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher2013-12-24
| | | | | | | | | | | | | | We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm: remove dev->vma_countDaniel Vetter2013-12-17
| | | | | | | | | | | | | | | This is just used for a debugfs file, and we can easily reconstruct this number by just walking the list twice. Which isn't really bad for a debugfs file anyway. So let's rip this out. There's the other issue that the dev->vmalist itself is a bit useless, since that can be reconstructed with all the memory mapping information from proc.

* drm: remove global_mutex locking around agp_initDaniel Vetter2013-12-17
| | | | | | | | | | | | | | | | | | | | David Herrmann dutifully moved this locking along when moving the agp_init call out of the generic drm_dev_register into the pci specific load helpers. But afaict there's no need and the reason for that locking has been purely a historical accident - we need the lock around the driver dev node registration to paper over the midlayer init races, and the agp init simply ended up in there. The real fix for all this is of course to delay the dev (and sysfs/debugfs) interface registration until everything is fully set up. Until then stop the cargo-cult locking from spreading and remove the locking.

* drm: remove agp_init() bus callbackDaniel Vetter2013-12-17
| | | | | | | | | | | | | | | | | | | The PCI bus helper is the only user of it. Call it directly before device-registration to get rid of the callback. Note that all drm_agp_*() calls are locked with the drm-global-mutex so we need to explicitly lock it during initialization. It's not really clear why it's needed, but lets be safe. v2: Rebase on top of the agp_init interface change. v3: Remove the rebase-fail where I've accidentally killed the ->irq_by_busid callback a bit too early.
