git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc These changes contain the OMAP USB related platform data changes that were dropped from linux next because of the merge conflicts as requested by me and Olof. The reason was that at this point we really should be able to do the arch/arm related changes separately from driver changes to avoid dependencies between branches. These patches were initially part of the USB related MFD patches. Based on our comments, Roger Quadros quickly reworked these patches into a shared branch between ARM SoC tree and the MFD tree, then separate patches for the OMAP platform data and MFD driver. Note that this branch will conflict with c1d1cd597fc7 ("ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code").

git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/soc From Stephen Warren: ARM: tegra: Common Clock Framework rework Tegra already supports the common clock framework, but had issues: 1) The clock driver was located in arch/arm/mach-tegra/ rather than drivers/clk/. 2) A single "Tegra clock" type was implemented, rather than separate clock types for PLL, mux, divider, ... type in HW. 3) Clock lookups by device drivers were still driven by device name and connection ID, rather than through device tree. This pull request solves all three issues. This required some DT changes to add clocks properties, and driver changes to request clocks more "correctly". Finally, this rework allows all AUXDATA to be removed from Tegra board files, and various duplicate clock lookup entries to be removed from the driver. This pull request is based on the previous pull request, with tag tegra-for-3.9-cleanup. * tag 'tegra-for-3.9-soc-ccf' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: (31 commits) clk: tegra30: remove unused TEGRA_CLK_DUPLICATE()s clk: tegra20: remove unused TEGRA_CLK_DUPLICATE()s ARM: tegra30: remove auxdata ARM: tegra20: remove auxdata ASoC: tegra: remove auxdata staging: nvec: remove use of clk_get_sys ARM: tegra: paz00: add clock information to DT ARM: tegra: add clock properties to Tegra30 DT ARM: tegra: add clock properties to Tegra20 DT spi: tegra: do not use clock name to get clock ARM: tegra: remove legacy clock code ARM: tegra: migrate to new clock code clk: tegra: add clock support for Tegra30 clk: tegra: add clock support for Tegra20 clk: tegra: add Tegra specific clocks ARM: tegra: define Tegra30 CAR binding ARM: tegra: define Tegra20 CAR binding ARM: tegra: move tegra_cpu_car.h to linux/clk/tegra.h ARM: tegra: add function to read chipid ARM: tegra: fix compile error when disable CPU_IDLE ...

2013-01-31drm/radeon: switch back to the CP ring for VM PT updatesAlex Deucher
For large VM page table updates, we can sometimes generate more packets than there is space on the ring. This happens more readily with the DMA ring since it is 64K (vs 1M for the CP). For now, switch back to the CP. For the next kernel, I have a patch to utilize IBs for VM PT updates which alleviates this problem.

2013-01-31drm/radeon: prevent crash in the ring space allocationAlex Deucher
If the requested number of DWs on the ring is larger than the size of the ring itself, return an error. In testing with large VM updates, we've seen crashes when we try and allocate more space on the ring than the total size of the ring without checking. This prevents the crash but for large VM updates or bo moves of very large buffers, we will need to break the transaction down into multiple batches. I have patches to use IBs for the next kernel.

2013-01-30efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming
Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

While the exynos DRM support in principle can work on multiplatform, the FIMD and IPP sections of it both include the plat/map-base.h header file, which is not available on multiplatform. Rather than disabling the entire driver, we can just conditionally build these two parts. Without this patch, building allyesconfig results in: drivers/gpu/drm/exynos/exynos_drm_fimc.c:19:27: fatal error: plat/map-base.h: No such file or directory drivers/gpu/drm/exynos/exynos_drm_ipp.c:20:27: fatal error: plat/map-base.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2013-01-25drm/exynos: don't include plat/gpio-cfg.hArnd Bergmann
Patch 9eb3e9e6f3 "drm/exynos: add support for ARCH_MULTIPLATFORM" allowed building the exynos hdmi driver on non-samsung platforms, which unfortunately broke compilation in combination with 22c4f42897 "drm: exynos: hdmi: add support for exynos5 hdmi", which added an inclusion of the samsung-specific plat/gpio-cfg.h header file. Fortunately, that header file is not required any more here, so we can simply revert the inclusion in order to build the ARM allyesconfig again without getting this error: drivers/gpu/drm/exynos/exynos_hdmi.c:37:27: fatal error: plat/gpio-cfg.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

2013-01-25drm/exynos: consider DMA_NONE flag to dmabuf importInki Dae
This patch considers DMA_NONE flag for other drivers not using dma mapping framework with iommu such as 3d gpu driver or others. For example, there might be 3d gpu driver that has its own iommu hw unit and iommu table mapping mechnism. So in this case, the dmabuf buffer imported into this driver needs just only sg table to map the buffer with its own iommu table itself. So this patch makes dma_buf_map_attachment ignore dma_map_sg call and just return sg table containing pages if dma_data_direction is DMA_NONE.

2013-01-25drm/exynos: free sg object if dma_map_sg is failedInki Dae
This patch releases sgt's sg object allocated by sgt_alloc_table correctly. When exynos_gem_map_dma_buf was called by dma_buf_map_attachmemt(), the sgt's sg object was allocated by sg_alloc_tale() so if dma_map_sg() is failed, the sg object should be released.

2013-01-25drm/exynos: let drm handle edid allocationsRahul Sharma
There's no need to allocate edid twice and do a memcpy when drm helpers exist to do just that. This patch cleans that interaction up, and doesn't keep the edid hanging around in the connector. v4: - removed error check for drm_mode_connector_update_edid_property which is expected to fail for Virtual Connectors like VIDI. Thanks to Seung-Woo Kim. v3: - removed MAX_EDID as it is not used anymore. v2: - changed vidi_get_edid callback inside vidi driver.

2013-01-23drm/radeon: fix a rare case of double kfreeIlija Hadzic
If one (but not both) allocations of p->chunks[].kpage[] in radeon_cs_parser_init fail, the error path will free the successfully allocated page, but leave a stale pointer value in the kpage[] field. This will later cause a double-free when radeon_cs_parser_fini is called. This patch fixes the issue by forcing both pointers to NULL after kfree in the error path. The circumstances under which the problem happens are very rare. The card must be AGP and the system must run out of kmalloc area just at the right time so that one allocation succeeds, while the other fails.
