drm/rcar-du: Update plane pitch in .mode_set_base() operation

2014-02-13T21:55:43Z

commit eb86301f293da3c362db729a9f40ddb25755902b upstream. When setting a new frame buffer with the mode set base operation the pitch value might change. Set the hardware plane pitch register at the same time as the plane base address in the rcar_du_plane_update_base() function to make sure the pitch value always matches the frame buffer.

drm: Add separate Kconfig option for fbdev helpers

2013-10-11T21:36:58Z

For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

drm: remove FASYNC support

2013-08-19T00:05:17Z

So I've stumbled over drm_fasync and wondered what it does. Digging that up is quite a story. First I've had to read up on what this does and ended up being rather bewildered why peopled loved signals so much back in the days that they've created SIGIO just for that ... Then I wondered how this ever works, and what that strange "No-op." comment right above it should mean. After all calling the core fasync helper is pretty obviously not a noop. After reading through the kernels FASYNC implementation I've noticed that signals are only sent out to the processes attached with FASYNC by calling kill_fasync. No merged drm driver has ever done that. After more digging I've found out that the only driver that ever used this is the so called GAMMA driver. I've frankly never heard of such a gpu brand ever before. Now FASYNC seems to not have been the only bad thing with that driver, since Dave Airlie removed it from the drm driver with prejudice: commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed Author: Dave Airlie Date: Sun Aug 29 12:04:35 2004 +0000 Drop GAMMA DRM from a great height ... Long story short, the drm fasync support seems to be doing absolutely nothing. And the only user of it was never merged into the upstream kernel. And we don't need any fops->fasync callback since the fcntl implementation in the kernel already implements the noop case correctly. So stop this particular cargo-cult and rip it all out. v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers (somehow I've missed that one in staging). Also drop the reference in the drm DocBook. ARM compile-fail reported by Rob Clark. v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this patch here. v4: Actually git add ... tsk.

2013-08-09T21:17:52Z

Split the output routing specification between SoC-internal data, specified in the rcar_du_device_info structure, and board data, passed through platform data. The DU has 5 possible outputs (DPAD0/1, LVDS0/1, TCON). SoC-internal output routing data specify which output are valid, which CRTCs can be connected to the valid outputs, and the type of in-SoC encoder for the output. Platform data then specifies external encoders and the output they are connected to. Signed-off-by: Laurent Pinchart
