2016-07-14drm/nouveau/volt: save the voltage range we are able to setKarol Herbst2-1/+16
We shouldn't set voltages below the min or above the max voltage the gpu is able to set, so save the range for future lookups.

2016-07-14drm/nouveau/clk/gm20b: add glitchless and DFS supportAlexandre Courbot4-98/+1002
This patch adds support for advanced features supported by the Noise-Aware PLL of Maxwell. Glitchless switch allows the PL field to be updated without disabling the PLL first if the SYNC_MODE bit of the CFG register is set. More significantly, DFS allows the PLL to monitor the actual input voltage and to dynamically lower the output frequency accordingly. This allows the clock to be more tolerant of lower voltages. These improvements are only supported for Tegra speedos >= 1. Also add the voltage table that is suitable for GM20B's NAPLL. This change needs to be done atomically for the right voltages to be used by the clock driver. v2.

2016-07-14drm/nouveau/clk/gk20a: improve MNP programmingAlexandre Courbot1-89/+96
Split the MNP programming function into two functions for the cases where we allow sliding or not, instead of making it take a parameter for this. This results in less conditionals in the code and makes it easier to read. Also make the MNP programming functions take the PLL parameters as arguments, and move bits of code to more relevant places (previous programming tended to be just-in-time, which added more conditionnals in the code).

2016-07-14drm/nouveau/clk/gk20a: factorize n_lo computation codeAlexandre Courbot1-9/+10

2016-07-14drm/nouveau/clk/gk20a: parameterize PLL settingsAlexandre Courbot1-24/+27
Make functions manipulating PLL settings take them as an argument, instead of assuming we want to work on the copy in the gk20a_clk structure. This makes these functions more flexible, which we will need in GM20B. Signed-off-by: Alexandre Courbot <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2016-07-14drm/nouveau/clk/gk20a: add and use MNP programming functionsAlexandre Courbot1-13/+22

There are cases where subdevs need to perform additonal actions around the master reset, so we want to expost the operations separately.

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 <[email protected]> Signed-off-by: Inki Dae <[email protected]>
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 <[email protected]> Signed-off-by: Inki Dae <[email protected]>
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 <[email protected]> Signed-off-by: Inki Dae <[email protected]>
2016-07-13drm/exynos: iommu: add a check if all sub-devices have iommu controllerMarek Szyprowski1-0/+5
This patch adds a check if all devices belonging to Exynos DRM have the same dma_map_ops set. This is required to enable operation with IOMMU enabled. Signed-off-by: Marek Szyprowski <[email protected]> Signed-off-by: Inki Dae <[email protected]>
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: Resurrect atomic rmfb codeDaniel Vetter3-0/+73
This was somehow lost between v3 and the merged version in Maarten's patch merged as: commit f2d580b9a8149735cbc4b59c4a8df60173658140 Author: Maarten Lankhorst <[email protected]> Date: Wed May 4 14:38:26 2016 +0200 drm/core: Do not preserve framebuffer on rmfb, v4. Actual code copied from Maarten's patch, but with the slight change to just use dev->mode_config.funcs->atomic_commit to decide whether to use the atomic path or not.

If imx-drm is combined with a bridge or panel that requests an unsupported format, warn and use a default mapping instead of hanging the machine. The worst that can happen here are wrong colors. Signed-off-by: Philipp Zabel <[email protected]>
2016-07-12drm/imx: imx-tve: fix the error messageFabio Estevam1-2/+2

2016-07-12drm/imx: store internal bus configuration in crtc statePhilipp Zabel6-107/+229
The internal bus configuration is imx-drm specific crtc state. Store it in imx_crtc_state and let the encoder atomic_check callbacks determine bus_flags, bus_format and the sync pins, possibly taking into account the mode and the connector display info. The custom imx_drm_encoder structure can be replaced again with drm_encoder. Signed-off-by: Philipp Zabel <[email protected]>

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.
