Included in this set are: - an update from Jean-Francois to add the missing reg documentation entry to the device tree documentation. - conversion of the tda998x driver to the component helpers. * 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox: drm/i2c: tda998x: add component support drm/i2c: tda998x: allow re-use of tda998x support code drm/i2c: tda998x: fix lack of required reg in DT documentation Conflicts: drivers/gpu/drm/i2c/tda998x_drv.c
| * drm/i2c: tda998x: add component supportRussell King2014-08-011-14/+198
| | | | | | | | | | | | | | | | | | | | | | | | Add component helper support to the tda998x driver. This permits the TDA998x to be declared as a separate device in device tree, and bound at the appropriate moment with a co-operating card driver. The existing slave_encoder interfaces are kept while there are existing users of it in order to prevent regressions.

| * drm/i2c: tda998x: allow re-use of tda998x support codeRussell King2014-08-011-69/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-jig the TDA998x code so that we separate the functionality from the drm slave encoder implementation. In several places, this is pretty clearly the correct thing to do, because we can avoid repetitively having to convert from the drm_encoder to the TDA998x private structure, particularly with the driver internal functions. The main motivation behind this change is to allow the code to be re-used with a standard drm_encoder and drm_connector implementation based on the component helpers, rather than the slave_encoder system. The addition of this will be in the following patch. We keep the slave_encoder interface as there are existing users of this; we need to give them time to convert and test.

| * drm/i2c: tda998x: move drm_i2c_encoder_destroy callGuido Martínez2014-06-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently tda998x_encoder_destroy() calls cec_write() and reg_clear(), as part of the release procedure. Such calls need to access the I2C bus and therefore, we need to call them before drm_i2c_encoder_destroy() which unregisters the I2C device. This commit moves the latter so it's done afterwards.

* | drm/i2c/tda998x: Fix signed overflow issueDaniel Vetter2014-04-221-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | This is C standard hair-splitting, but afaict - sum will be promoted to signed int in computation since uint8_t fits - signed overflow is undefined. No we need to add up an awful lot of bytes to actually make it overflow. But I guess the real risk is gcc spotting this and going bananas. Fix this by simply using unsigned in to force all computations to use the well-defined unsigned behaviour. Spotted by coverity. v2: Simplify the entire computation as suggested by Jean.

Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless. A few other small semantic conflicts too, noted from Dave's pre-merged branch. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits) drm/nv98/crypt: fix fuc build with latest envyas drm/nouveau/devinit: fixup various issues with subdev ctor/init ordering drm/nv41/vm: fix and enable use of "real" pciegart drm/nv44/vm: fix and enable use of "real" pciegart drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcie drm/nouveau: store supported dma mask in vmmgr drm/nvc0/ibus: initial implementation of subdev drm/nouveau/therm: add support for fan-control modes drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rules drm/nouveau/therm: calculate the pwm divisor on nv50+ drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster drm/nouveau/therm: move thermal-related functions to the therm subdev drm/nouveau/bios: parse the pwm divisor from the perf table drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devices drm/nouveau/therm: rework thermal table parsing drm/nouveau/gpio: expose the PWM/TOGGLE parameter found in the gpio vbios table drm/nouveau: fix pm initialization order drm/nouveau/bios: check that fixed tvdac gpio data is valid before using it drm/nouveau: log channel debug/error messages from client object rather than drm client drm/nouveau: have drm debugging macros build on top of core macros ...
