2016-07-14drm/tegra: sor: Implement sor1_brick clockThierry Reding
sor1_brick is a clock that can be used as a source for the sor1 clock. The registers to control the clock output are part of the sor1 IP block and hence the sor driver is the best place to implement it. Signed-off-by: Thierry Reding <treding@nvidia.com>
2016-07-14drm/imx: parallel-display: add bridge supportPhilipp Zabel
Add support for bridge chips connected externally to the i.MX DISP0/DISP1 DPI interfaces. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-07-14drm: Don't overwrite user ioctl arg unless requestedChris Wilson
Currently, we completely ignore the user when it comes to the in/out direction of the ioctl argument, as we simply cannot trust userspace. (For example, they might request a copy of the modified ioctl argument when the driver is not expecting such and so leak kernel stack.) However, blindly copying over the target address may also lead to a spurious EFAULT, and a failure after the ioctl was completed successfully. This is important in order to avoid an ABI break when extending an ioctl from IOR to IORW. Similar to how we only copy the intersection of the kernel arg size and the user arg size, we only want to copy back the kernel arg data iff both the kernel and userspace request the copy.

2016-07-14Merge branch 'linux-4.8' of git://github.com/skeggsb/linux into drm-nextDave Airlie
Here's an initial drm-next pull for nouveau 4.8, highlights: - GK20A/GM20B volt and clock improvements. - Initial support for GP100/GP104 GPUs, GP104 will not yet support acceleration due to NVIDIA having not released firmware for them as of yet. * 'linux-4.8' of git://github.com/skeggsb/linux: (97 commits) drm/nouveau/bus: remove cpu_coherent flag drm/nouveau/ttm: remove special handling of coherent objects drm/nouveau: check for supported chipset before booting fbdev off the hw drm/nouveau/ce/gp104: initial support drm/nouveau/fifo/gp104: initial support drm/nouveau/disp/gp104: initial support drm/nouveau/dma/gp104: initial support drm/nouveau/ltc/gp104: initial support drm/nouveau/ibus/gp104: initial support drm/nouveau/i2c/gp104: initial support drm/nouveau/gpio/gp104: initial support drm/nouveau/fuse/gp104: initial support drm/nouveau/bus/gp104: initial support drm/nouveau/bar/gp104: initial support drm/nouveau/mmu/gp104: initial support drm/nouveau/fb/gp104: initial support drm/nouveau/imem/gp104: initial support drm/nouveau/devinit/gp104: initial support drm/nouveau/bios/gp104: initial support drm/nouveau/tmr/gp104: initial support ...
2016-07-14drm/nouveau/bus: remove cpu_coherent flagAlexandre Courbot
This flag's only remaining function is to ignore the uncached flag for BOs on coherent architectures. However the reason for allocating an object uncache on a non-coherent architecture (namely because the cost of doing explicit flushes/ invalidations is higher than the benefit of caching the data because accesses are few and far between) should also apply on architectures for which coherency is maintained implicitly. Thus allocate coherent objects as uncached on all architectures. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/ttm: remove special handling of coherent objectsAlexandre Courbot
TTM-allocated coherent objects were populated using the DMA API and accessed using the mapping it returned to workaround coherency issues. These issues seem to have been solved, thus remove this extra case to handle and use the regular kernel mapping functions.
