2016-07-18drm/arm: make fbdev support really optionalTobias Jakobi1-1/+0
Currently enabling ARM HDLCD DRM support automatically pulls in fbdev dependency. However this dep is unnecessary since DRM core already handles this for us (DRM_FBDEV_EMULATION).

2016-07-18drm/hdlcd: Delete an unnecessary check before drm_fbdev_cma_hotplug_event()Markus Elfring1-2/+1
The drm_fbdev_cma_hotplug_event() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2016-06-02drm: hdlcd: Cleanup the atomic plane operationsLiviu Dudau2-17/+29
Harden the plane_check() code to drop attempts at scaling because that is not supported. Make hdlcd_plane_atomic_update() set the pitch and line length registers that correctly reflect the plane's values. And make hdlcd_crtc_mode_set_nofb() a helper function for hdlcd_crtc_enable() rather than an exposed hook. Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Liviu Dudau <Liviu.Dudau@arm.com>

2016-06-02drm: hdlcd: Revamp runtime power managementLiviu Dudau3-35/+39
Because the HDLCD driver acts as a component master it can end up enabling the runtime PM functionality before the encoders are initialised. This can cause crashes if the component slave never probes (missing module) or if the PM operations kick in before the probe finishes. Move the enabling of the runtime PM after the component master has finished collecting the slave components and use the DRM atomic helpers to suspend and resume the device.

2016-05-21drm: Nuke ->vblank_disable_allowedDaniel Vetter1-1/+0
This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.
