* video: da8xx-fb: enable sync lost intr for v2 ipAfzal Mohammed2013-08-091-1/+1
| | | | | | | | | | | | | The interrupt handler explicitly has code that handles the sync lost interrupt. However the sync lost interrupt is never actually being enabled in the LCD controller, therefore this interrupt code path is not being exercised. This fix simply enables the generation of the sync lost interrupt by the LCD controller so it can be dealt with appropriately by the interrupt handler.

| | | | | | | | | | | | | | | | | Based on original patch by: Manjunathappa, Prakash <prakash.pm@ti.com> and Afzal Mohammed <afzal@ti.com> Set only LCD_V2_TFT_24BPP_MODE bit for 24bpp and LCD_V2_TFT_24BPP_UNPACK bit along with LCD_V2_TFT_24BPP_MODE for 32bpp configuration. Patch is tested on am335x-evm for 24bpp and da850-evm for 16bpp configurations. v2: removes confusing fall through in case statement for pixel depth configuration.

* video: da8xx-fb: fb_set_par supportDarren Etheridge2013-08-091-11/+47
| | | | | | | | | | | | | | | | | | | | v1: original from Afzal Mohammed <afzal@ti.com> fb_set_par helps in runtime configuration of lcd controller like changing resolution, pixel clock etc. (eg. using fbset utility) Reconfigure lcd controller based on information passed by framework. Enable raster back if it was already enabled. As fb_set_par would get invoked indirectly from probe via fb_set_var, remove existing lcdc initialization in probe and do lcdc reset in probe so that reset happens only at the begining. v2: changes from Darren Etheridge <detheridge@ti.com> remove unnecessary conditional branch where we attempt to disable something that we already checked to see if it was disabled.

| | | | | | | | | | | | | | | | | | | Based on original patch by: Afzal Mohammed <afzal@ti.com> Use the new modedb field to store pix clk. Reorganize existing clock divider functions with names now corresponding to what they do, add common function prefix. Fix existing panel modedb pixclock to be in ps instead of Hz. This needed a change in the way clock divider is calculated. As modedb pixclock information is now in ps, override on "var" pixclock over modedb to var conversion is removed. v2: Changed pixel clock configuration to use KHZ2PICOS macro Signed-off-by: Darren Etheridge <detheridge@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

While at it, remove redundant update of bits_per_pixel.

In future I'll just take the patch myself! Outside drm: There are some snd changes for the HDMI audio interactions on haswell, they've been acked for inclusion via my tree. This relies on the wound/wait tree from Ingo which is already merged. Major changes: AMD finally released the dynamic power management code for all their GPUs from r600->present day, this is great, off by default for now but also a huge amount of code, in fact it is most of this pull request. Since it landed there has been a lot of community testing and Alex has sent a lot of fixes for any bugs found so far. I suspect radeon might now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable dynamic powermanagement for anyone. New drivers: Renesas r-car display unit. Other highlights: - core: GEM CMA prime support, use new w/w mutexs for TTM reservations, cursor hotspot, doc updates - dvo chips: chrontel 7010B support - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell), Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp support (this time for sure) - nouveau: async buffer object deletion, context/register init updates, kernel vp2 engine support, GF117 support, GK110 accel support (with external nvidia ucode), context cleanups. - exynos: memory leak fixes, Add S3C64XX SoC series support, device tree updates, common clock framework support, - qxl: cursor hotspot support, multi-monitor support, suspend/resume support - mgag200: hw cursor support, g200 mode limiting - shmobile: prime support - tegra: fixes mostly I've been banging on this quite a lot due to the size of it, and it seems to okay on everything I've tested it on." * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (811 commits) drm/radeon/dpm: implement vblank_too_short callback for si drm/radeon/dpm: implement vblank_too_short callback for cayman drm/radeon/dpm: implement vblank_too_short callback for btc drm/radeon/dpm: implement vblank_too_short callback for evergreen drm/radeon/dpm: implement vblank_too_short callback for 7xx drm/radeon/dpm: add checks against vblank time drm/radeon/dpm: add helper to calculate vblank time drm/radeon: remove stray line in old pm code drm/radeon/dpm: fix display_gap programming on rv7xx drm/nvc0/gr: fix gpc firmware regression drm/nouveau: fix minor thinko causing bo moves to not be async on kepler drm/radeon/dpm: implement force performance level for TN drm/radeon/dpm: implement force performance level for ON/LN drm/radeon/dpm: implement force performance level for SI drm/radeon/dpm: implement force performance level for cayman drm/radeon/dpm: implement force performance levels for 7xx/eg/btc drm/radeon/dpm: add infrastructure to force performance levels drm/radeon: fix surface setup on r1xx drm/radeon: add support for 3d perf states on older asics drm/radeon: set default clocks for SI when DPM is disabled ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code allowed very strange memory types. Now it works like all the other video drivers: ioremap_wc is used unconditionally, and MTRRs are set if PAT is unavailable (unless MTRR is disabled by a module parameter). UC, WB, and WT support is gone. If there are MTRR conflicts that prevent addition of a WC MTRR, adding a non-conflicting MTRR is pointless; it's better to just turn off MTRR support entirely. As an added bonus, any MTRR added is freed on unload.

This part contains the new DSS device model support. The current OMAP panel drivers use a custom DSS bus, and there's a hard limit of one external display block per video pipeline. In the new DSS device model the devices/drivers are made according to the control bus of the display block, usually platform, i2c or spi. The display blocks can also be chained so that we can have separate drivers for setups with both external encoder and panel. To allow the current board files, which use the old style panels, to function, the old display drivers are left in their current state, and new ones are added to drivers/video/omap2/displays-new/. When the board files have been converted to use the new style panels, we can remove the old code. This is planned to happen in v3.12. Having to support two very different DSS device models makes the driver somewhat confusing in some parts, and prevents us from properly cleaning up some other parts. These cleanups will be done when the old code is removed. The new device model is designed with CDF (Common Display Framework) in mind. While CDF is still under work, the new DSS device model should be much more similar to CDF's model than the old device model, which should make the eventual conversion to CDF much easier.
