2013-08-07drm/gem: create drm_gem_dumb_destroyDaniel Vetter1-1/+1
All the gem based kms drivers really want the same function to destroy a dumb framebuffer backing storage object. So give it to them and roll it out in all drivers. This still leaves the option open for kms drivers which don't use GEM for backing storage, but it does decently simplify matters for gem drivers.

2013-06-28drm/tilcdc fixing i2c/slave initialization raceDarren Etheridge3-25/+40
In certain senarios drm will initialize before i2c this means that i2c slave devices like the nxp tda998x will fail to be probed. This patch detects this condition then defers the probe of the slave device and the tilcdc main driver.

2013-06-28drm/tilcdc: adding more guards to prevent selection of invalid modesDarren Etheridge1-0/+46
The tilcdc has a number of limitations for the allowed sizes of the various adjustable timing parameter. Some modes are outside of these timings. This commit will prune modes that report timings that will overflow the allowed sizes in the tilcdc.

2013-06-28drm/tilcdc: fixing off by one errors found on analyzerDarren Etheridge1-7/+12
When hooking up to an HDMI analyzer noticed some timings were off by one. Referring to the hardware technical reference manual for the lcd controller some of the timing registers use 0 to represent 1. This patch addresses that issue.

2013-06-20gpu:drm:tilcdc: get preferred_bpp value from DTBenoit Parrot5-1/+18
The preferred_bpp value in currently hard-coded to 16. This causes color corruption on the am335x-evm lcd panel which requires 32 bpp instead.

2013-06-17drm: Drop all the stub gamma_get, gamma_set, load_lut functions from driversVille Syrjälä1-5/+0
Many of the drivers didn't implement palette/gamma handling, but were forced to provide stubs for the hooks to avoid drm_fb_helper from oopsing. Now that the hooks are optional, we can eliminate all the stubs.

2013-04-26drm/tilcdc: use only a single module device tableArnd Bergmann3-3/+0
The tilcdc driver fails to be built as a module because of extraneous MODULE_DEVICE_TABLE entries: drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here Since the entire point of these entries is to make the module autoload when one of the devices is present, it's enough to keep the one entry for "ti,am33xx-tilcdc", which should always be there if any of the others are.

2013-03-21videomode: videomode_from_timing workTomi Valkeinen1-1/+1
We currently have videomode_from_timing(), which takes one display_timing entry from display_timings. To make it easier to use display_timing without display_timings, this patch renames videomode_from_timing() to videomode_from_timings(), and adds a new videomode_from_timing() which just converts a given display_timing to videomode.

2013-03-12videomode: simplify videomode Kconfig and MakefileTomi Valkeinen1-2/+1
This patch simplifies videomode related Kconfig and Makefile. After this patch, there's only one non-user selectable Kconfig option left, VIDEOMODE_HELPERS. The reasons for the change: * Videomode helper functions are not something that should be shown in the kernel configuration options. The related code should just be included if it's needed, i.e. selected by drivers using videomode. * There's no need to have separate Kconfig options for videomode and display_timing. First of all, the amount of code for both is quite small. Second, videomode depends on display_timing, and display_timing in itself is not really useful, so both would be included in any case. * CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS describes better what's included.

2013-02-19drm/tilcdc: add TI LCD Controller DRM driver (v4)Rob Clark8-0/+1974
A simple DRM/KMS driver for the TI LCD Controller found in various smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the CMA helpers. Currently only the TFP410 DVI encoder is supported (tested with beaglebone + DVI cape). There are also various LCD displays, for which support can be added (as I get hw to test on), and an external i2c HDMI encoder found on some boards. The display controller supports a single CRTC. And the encoder+ connector are split out into sub-devices. Depending on which LCD or external encoder is actually present, the appropriate output module(s) will be loaded. v1: original v2: fix fb refcnting and few other cleanups v3: get +/- vsync/hsync from timings rather than panel-info, add option DT max-bandwidth field so driver doesn't attempt to pick a display mode with too high memory bandwidth, and other small cleanups v4: remove some unneeded stuff from panel-info struct, properly set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs Signed-off-by: Rob Clark <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Tested-by: Koen Kooi <[email protected]>
