2014-10-14Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds1-10/+9
Pull drm updates from Dave Airlie: "This is the main git pull for the drm, I pretty much froze major pulls at -rc5/6 time, and haven't had much fallout, so will probably continue doing that. Lots of changes all over, big internal header cleanup to make it clear drm features are legacy things and what are things that modern KMS drivers should be using. Also big move to use the new generic fences in all the TTM drivers. core: atomic prep work, vblank rework changes, allows immediate vblank disables major header reworking and cleanups to better delinate legacy interfaces from what KMS drivers should be using. cursor planes locking fixes ttm: move to generic fences (affects all TTM drivers) ppc64 caching fixes radeon: userptr support, uvd for old asics, reset rework for fence changes better buffer placement changes, dpm feature enablement hdmi audio support fixes intel: Cherryview work, 180 degree rotation, skylake prep work, execlist command submission full ppgtt prep work cursor improvements edid caching, vdd handling improvements nouveau: fence reworking kepler memory clock work gt21x clock work fan control improvements hdmi infoframe fixes DP audio ast: ppc64 fixes caching fix rcar: rcar-du DT support ipuv3: prep work for capture support msm: LVDS support for mdp4, new panel, gpu refactoring exynos: exynos3250 SoC support, drop bad mmap interface, mipi dsi changes, and component match support" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (640 commits) drm/mst: rework payload table allocation to conform better. drm/ast: Fix HW cursor image drm/radeon/kv: add uvd/vce info to dpm debugfs output drm/radeon/ci: add uvd/vce info to dpm debugfs output drm/radeon: export reservation_object from dmabuf to ttm drm/radeon: cope with foreign fences inside the reservation object drm/radeon: cope with foreign fences inside display drm/core: use helper to check driver features drm/radeon/cik: write gfx ucode version to ucode addr reg drm/radeon/si: print full CS when we hit a packet 0 drm/radeon: remove unecessary includes drm/radeon/combios: declare legacy_connector_convert as static drm/radeon/atombios: declare connector convert tables as static drm/radeon: drop btc_get_max_clock_from_voltage_dependency_table drm/radeon/dpm: drop clk/voltage dependency filters for BTC drm/radeon/dpm: drop clk/voltage dependency filters for CI drm/radeon/dpm: drop clk/voltage dependency filters for SI drm/radeon/dpm: drop clk/voltage dependency filters for NI drm/radeon: disable audio when we disable hdmi (v2) drm/radeon: split audio enable between eg and r600 (v2) ...

2014-04-14ARM: shmobile: lager-reference: Work around core clock issuesSimon Horman1-0/+11
Due to issues with runtime PM clock management, clocks not explicitly managed by their drivers may not be enabled at all, or be inadvertently disabled by the clk_disable_unused() late initcall. Until this is fixed, add a temporary workaround, calling shmobile_clk_workaround() with enable == true. For now this enables the clocks for: ether, msiof1, qspi_mod, and thermal. More clocks can be added if needed. Based on work for the koelsch board by Geert Uytterhoeven.

2014-02-04ARM: shmobile: lager: fix error return code check from clk_get()Ben Dooks1-2/+2
The lager_add_standard_devices() function calls clk_get() but then fails to check that it returns an error pointer instead of NULL on failure. This was added by 4a606af2 ("ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMT") patch in Simon Horman's renesas-boards2-for-v3.14 tag. The issue is not serious as it does not cause a crash and seems to not be actually causing any issues now the other clock bugs have been fixed.

2013-12-19ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMTLaurent Pinchart1-1/+30
Now that the common clock framework is supported, the clock lookup entries in clock-r8a7790.c are not registered anymore. Devices must instead reference their clocks in the device tree. However, SCIF and CMT devices are still instantiated through platform code, and thus need a clock lookup entry. Retrieve the SCIF and CMT clock entries by name and register clkdevs for the corresponding devices. This will be removed when the SCIF and CMT devices will be instantiated from the device tree.

2013-07-17ARM: shmobile: lager: Add DT referenceSimon Horman1-0/+46
This is sufficient to allow boot of the Lager board with a console without boards-lager.c compiled into the kernel. This is an example of a minimal but still useful initialisation of the board using DT as much as possible. As such it is the same as the boot of Lager that can be achieved without a board file. The intention of adding this file is to facilitate further work to allow board specific devices to be initialised via DT.
