* drm/omap: Stop using drm_framebuffer_unregister_privateDaniel Vetter2017-01-121-6/+2
| | | | | | | | | | | This is the deprecated function for when you embedded the framebuffer somewhere else (which breaks refcounting). But omapdrm is using drm_framebuffer_remove and a free-standing fb, so this is rendundant.

* drm/omap: fix pitch round-upTomi Valkeinen2016-06-061-2/+2
| | | | | | | | | | | | | | | | | At the moment we calculate the buffer's pitch with: pitch = width * DIV_ROUND_UP(bpp, 8) For CLUT modes with bpp of 1/2/4/8 this gives wrong result, and the correct pitch is: pitch = DIV_ROUND_UP(width * bpp, 8) In practice this doesn't change anything, as we don't support CLUT modes, but it's better to have the pitch calculation correct.

* drm/omap: remove align_pitch()Tomi Valkeinen2016-06-061-3/+2
| | | | | | | | | | | | The previous commit removed aligning the pitch to SGX's pitch requirement from align_pitch(). What's left is effectively a function that returns width * bytespp. To clean up the driver, we can remove the function and have the calculation inline in the two places which call align_pitch().

* drm/omap: fix fbdev pix format to support all platformsTomi Valkeinen2015-12-141-4/+1
| | | | | | | | | | | | | omap_fbdev always creates a framebuffer with ARGB8888 pixel format. On OMAP3 we have VIDEO1 overlay that does not support ARGB8888, and on OMAP2 none of the overlays support ARGB888. This patch changes the omap_fbdev's fb to XRGB8888, which is supported by all platforms. Signed-off-by: Tomi Valkeinen <[email protected]> Tested-by: H.

* drm: Introduce drm_fb_helper_prepare()Thierry Reding2014-07-081-1/+1
| | | | | | | | | | | | | | | | | | | | | To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

* drm/omap: move out of stagingRob Clark2013-02-161-0/+402
Now that the omapdss interface has been reworked so that omapdrm can use dispc directly, we have been able to fix the remaining functional kms issues with omapdrm. And in the mean time the PM sequencing and many other of that open issues have been solved. So I think it makes sense to finally move omapdrm out of staging.
