| * drm/nv50-: trigger update after all connectors disabledBen Skeggs2014-06-111-0/+1
| | | | | | | | | | | | | | | | We were sending the necessary state changes to unset the mode, but never actually hit the big GO button unless another modeset happens afterwards. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nouveau/disp/dp: make use of postcursor when its availableBen Skeggs2014-06-111-8/+18
| | | | | | | | | | | | And at the same time, obey the spec better wrt out-of-range requests. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nouveau/dp: fix support for dpmsBen Skeggs2014-06-112-4/+50
| | | | | | | | | | | | | | | | | | | | SOR_PWR has no effect to power-off DP links, unlike other SOR protocols. Instead, on the source side, we cut power to the lanes after having put the sink into D3. Link training takes care of everything required to bring it back again.

| * drm/nouveau/disp/dp: maintain link in response to hpd signalBen Skeggs2014-06-116-12/+125
| | | | | | | | | | | | | | | | | | This previously worked for the most part due to userspace doing a modeset in response to HPD interrupts. This will allow us to properly handle cases where sync is lost for other reasons, or if userspace isn't caring. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| * drm/g94-/disp: bash and wait for something after changing lane power regsBen Skeggs2014-06-111-0/+3
| | | | | | | | | | | | Some kind of update? Needed to make the power-down take effect at least. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| * drm/nouveau/disp/dp: split link config/power into two stepsBen Skeggs2014-06-116-12/+29
| | | | | | | | | | | | We want to be able to power down the lanes for DPMS off. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| * drm/nv50/disp: train PIOR-attached DP from second supervisorBen Skeggs2014-06-111-21/+11

| * drm/nouveau/disp: add internal representaion of output paths and connectorsBen Skeggs2014-06-1110-2/+619
| | | | | | | | | | | | | | | | This will, at some point, be used to replace various bits and pieces of code doing direct bios parsing. For now, it'll just be used for some DP improvements. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nouveau/i2c: introduce locking at a per-port levelBen Skeggs2014-06-1114-34/+380
| | | | | | | | | | | | | | | | | | | | There's also provisions to allow a pad to be locked with a specific routing, for an indefinite period of time. This will be used in future patches. The G94+ pad driver will now also power-down pads when not required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| * drm/nouveau/i2c: balance port acquire/releaseBen Skeggs2014-06-114-14/+56
| | | | | | | | | | | | | | | | | | | | | | This was a half-finished hack before, just enough to handle the shared aux/i2c pad thing on G94 and up. We got lucky with locking etc up until now, as this was (generally) all protected by the DRM mode_config lock. It's about to become a lot more likely to hit the races.

| | | | | | | | | | | | | | | | | | | | | | | | IPU_CONF_..._EN bits are implementation details, not to be made public. Add wrappers around ipu_module_enable/disable, so the CSI V4L2 driver can enable/disable the CSI and SMFC modules. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX Image Processing Unit (IPU) contains a number of image processing blocks that sit right in the middle between DRM and V4L2. Some of the modules, such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS Sensor Interface (CSI) and their FIFOs could be assigned to either framework, but others, such as the dma controller (IDMAC) and image converter (IC) can be used by both. The IPUv3 core driver provides an internal API to access the modules, to be used by both DRM and V4L2 IPUv3 drivers.
