2016-07-14drm/nouveau/mc: expose device enable/disable separately, as well as resetBen Skeggs3-15/+38
There are cases where subdevs need to perform additonal actions around the master reset, so we want to expost the operations separately. This commit also adds a flag to the NV_PMC_ENABLE bitfield definitions which allow skipping the automatic reset() called from core/subdev.c. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-07-13drm/exynos: iommu: add support for ARM64 specific code for IOMMU glueMarek Szyprowski3-7/+57
This patch adds support for ARM 64bit architecture with IOMMU-DMA glue code, so Exynos DRM can be now used on Exynos 5433 with IOMMU enabled. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: move ARM specific code to exynos_drm_iommu.hMarek Szyprowski2-33/+42
This patch moves all ARM 32bit DMA-mapping/IOMMU dependant code from exynos_drm_iommu.c to .h, to let it compile conditionally and prepare for adding support for other architectures/IOMMU glue code (like ARM 64bit with IOMMU-DMA glue). Later, when ARM 32bit and 64bit will be unified, this code can be removed. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: remove unused entries from exynos_drm_private strcutureMarek Szyprowski2-9/+2
This patch removes unused entries from exynos_drm_private strcuture. da_start/da_space_size were only used in drm_create_iommu_mapping() function and never set to other value than the defaults. Instead use default values directly in arm_iommu_create_mapping() call. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: add a check if all sub-devices have iommu controllerMarek Szyprowski1-0/+5

2016-07-13drm/exynos: iommu: move dma_params configuration code to separate functionsMarek Szyprowski1-6/+22
Move code for managing DMA max segment size parameter to separate functions. This patch also replaces devm_kzalloc() with kzalloc() and adds proper kfree call. devm_kzalloc() cannot be used for dma_params structure, because it will be freed on driver remove not on device release. This means in case of Exynos DRM being compiled as module and loaded 2 times, a user-after-free issue will happen.

2016-07-13drm/i915: Unbreak interrupts on pre-gen6Ville Syrjälä1-1/+2
Prior to gen6 we didn't have per-ring IMR registers, which means that since commit 61ff75ac20ff ("drm/i915: Simplify enabling user-interrupts with L3-remapping") we're now masking off all interrupts when init_render_ring() gets called. That's rather rude. Let's limit the ring IMR frobbing to machines that actually have the per-ring IMR registers.

2016-07-13drm/bridge: adv7533: Change number of DSI lanes dynamicallyArchit Taneja3-0/+31
Lower modes on ADV7533 require lower number of DSI lanes for correct operation. If ADV7533 is being used with 4 DSI lanes, then switch the lanes to 3 when the target mode's pixel clock is less than 80 Mhz. Based on patch by Andy Green <andy.green@linaro.org> Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-07-13drm/bridge: adv7533: Use internal timing generatorArchit Taneja3-2/+63
ADV7533 provides an internal timing generator for certain modes that it can't use the DSI clock directly. We've observed that HDMI is more stable with the internal timing generator, especially if there are instabilities in the DSI clock source. The data spec also seems to recommend the usage of the timing generator for all modes. However, on some platforms, it's reported that enabling the timing generator causes instabilities with the HDMI output. Create a DT parameter that lets a platform explicitly disable the timing generator. The timing generator is enabled by default. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-07-13drm/bridge: adv7533: Create a MIPI DSI deviceArchit Taneja4-8/+147
In order to pass DSI specific parameters to the DSI host, we need the driver to create a mipi_dsi_device DSI device that attaches to the host. Use of_graph helpers to get the DSI host DT node. Create a MIPI DSI device using this host. Finally, attach this device to the DSI host. Populate DT parameters (number of data lanes for now) that are required for DSI RX to work correctly. Hardcode few other parameters (rgb, embedded_sync) for now. Select DRM_MIPI_DSI config option only when ADV7533 support is enabled. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-07-13drm/bridge: adv7533: Initial support for ADV7533Archit Taneja5-49/+230
ADV7533 is a DSI to HDMI encoder chip. It is a derivative of ADV7511, with additional blocks to translate input DSI data to parallel RGB data. Besides the ADV7511 I2C register map, it has additional registers that require to be configured to activate the DSI Rx block. Create a new config that enables ADV7533 support. Use DT compatible strings to populate the ADV7533 type enum. Add minimal register configurations belonging to the DSI/CEC register map. Keep the ADV7533 code in a separate file. Originally worked on by Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-07-13drm/bridge: adv7511: Fix mutex deadlock when interrupts are disabledArchit Taneja1-4/+4
When the adv7511 i2c client doesn't have an interrupt line, we observe a deadlock on caused by trying to lock drm device's mode_config.mutex twice in the same context. Here is the sequence that causes it: ioctl DRM_IOCTL_MODE_GETCONNECTOR from userspace drm_mode_getconnector (acquires mode_config mutex) connector->fill_modes() drm_helper_probe_single_connector_modes connector_funcs->get_modes adv7511_encoder_get_modes adv7511_get_edid_block adv7511_irq_process drm_helper_hpd_irq_event (acquires mode_config mutex again) In adv7511_irq_process, don't call drm_helper_hpd_irq_event when not called from the interrupt handler. It doesn't serve any purpose there anyway. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-07-13drm/i2c: adv7511: Move to bridge folderArchit Taneja8-9/+12
The driver has been converted to use drm_bridge instead of drm_i2c_slave_encoder. We can now move it to the bridge folder. Create a separate folder since we already have a couple of files and expect more when we support audio and ADV7533. Rename the driver to adv7511_drv.c. This will come in handy later when the driver module will need to be built from multiple object files. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-07-13drm/i2c: adv7511: Convert to drm_bridgeArchit Taneja2-74/+140
We don't want to use the old i2c slave encoder interface anymore. Remove that and make the i2c driver create a drm_bridge entity instead. Converting to bridges helps because the kms drivers don't need to exract encoder slave ops from this driver and use it within their own encoder/connector ops. The driver now creates its own connector when a kms driver attaches itself to the bridge. Therefore, kms drivers don't need to create their own connectors anymore. The old encoder slave ops are now used by the new bridge and connector entities. The of_node member in drm_bridge is accessible only when CONFIG_OF is enabled. The driver anyway only works only when OF is available. Make the driver depend on OF in its Kconfig. Signed-off-by: Archit Taneja <architt@codeaurora.org>

2016-07-12drm/imx: atomic phase 3 step 2: Legacy callback fixupsLiu Ying5-82/+27
Now that we can use atomic configurations, all the legacy callbacks of CRTCs, encoders and connectors can be switched to the atomic version. For the imx-ldb driver, there is a clock parent setting mismatch bewteen ->enable and ->disable after the switch, so a fixup is added. For the imx-tve driver, since the encoder's callback ->dpms is replaced by ->disable, we need to move the setting for the IPU_CLK_EN bit(in register TVE_COM_CONF_REG) from ->enable/->disable to ->mode_set, otherwise, the relevant CRTC cannot be disabled correctly with a warning on DC stop timeout.

2016-07-12drm/imx: atomic phase 3 step 1: Use atomic configurationLiu Ying4-308/+114
Replacing drm_crtc_helper_set_config() by drm_atomic_helper_set_config() and converting the suspend/resume operations to atomic make us be able to use atomic configurations. All of these allow us to remove the crtc_funcs->mode_set callback as it is no longer used. Also, change the plane_funcs->update/disable_plane callbacks from the transitional version to the atomic version. Furthermore, switching to the pure atomic version of set_config callback means that we may implement CRTC/plane atomic checks by using the new CRTC/plane states instead of the legacy ones and we may remove the private ipu_crtc->enabled state which was left there for the transitional atomic helpers in phase 1. Page flip is also switched to the atomic version. Last, the legacy function drm_helper_disable_unused_functions() is removed from ->load in order not to confuse the atomic driver.

2016-07-12drm/imx: Remove encoders' ->prepare callbacksLiu Ying7-203/+142
The main task of imx encoders' ->prepare callbacks is to set bus_format, bus_flags, di_vsync_pin and di_hsync_pin. We may create a structure named imx_encoder to cache them. The atomic encoder callback ->disable may replace ->prepare later, so let's remove ->prepare.

Use the drm_plane_helper_update/disable() and drm_helper_crtc_mode_set() transitional atomic helpers. The crtc->mode_set_nofb callback is added so that the primary plane is no longer tied to the CRTC. Check/update logics are separated to make sure crtc->mode_set_nofb and plane->atomic_update are always successful. Also, some necessary logics are tweaked for a smooth transition.

For all video modes we support currently, we always get 2 slots for a plane by using the current existing dynamic DMFC FIFO allocation mechanism. So, let's change to use the static one to simplify the code. This also makes it easier to implement the atomic mode setting as we don't need to handle allocation failure cases then.
