2017-12-19drm/omap: DMM: Fix DMM_IRQSTAT_ERR_MASK definitionPeter Ujfalusi
The error bit definitions are typoed in DMM_IRQSTAT_ERR_MASK which went unnoticed since the DMM_IRQSTAT_ERR_MASK was not used. Change the bit definitions to the correct ones. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2017-12-19drm: omapdrm: Deconstruct the omap_drv.h header.Laurent Pinchart

2017-12-19drm/omap: Filter displays mode based on bandwidth limitPeter Ujfalusi
If we have memory bandwidth limit configured, reject the modes which would require more bandwidth than the limit if it is used with one full resolution plane (most common use case). This filtering is not providing full protection as it is possible that application would pick smaller crtc resolution with high resolution planes and down scaling, or can enable more smaller planes where the sum of their bandwidth need would be higher than the limit. This patch only allows us to filter out modes which would need more bandwidth if they were used with one full screen plane.

2017-12-18drm/tilcdc: Remove drm_framebuffer_get() and *_put() callsJyri Sarha
The drm_framebuffer_get() and drm_framebuffer_put() calls in the tilcdc driver are obsolete. The drm atomic modesetting core should take care of holding the references while the atomic state object is in use. The old state is deleted when a commit of a new one is completed after drm_atomic_helper_wait_for_vblanks(). This also fixes an occasional framebuffer leak the old drm_framebuffer_get() and drm_framebuffer_put() code had. Signed-off-by: Jyri Sarha <jsarha@ti.com>
2017-12-18drm/tilcdc: ensure nonatomic iowrite64 is not usedLogan Gunthorpe
Add a check to ensure iowrite64 is only used if it is atomic. It was decided in [1] that the tilcdc driver should not be using an atomic operation (so it was left out of this patchset). However, it turns out that through the drm code, a nonatomic header is actually included: include/linux/io-64-nonatomic-lo-hi.h is included from include/drm/drm_os_linux.h:9:0, from include/drm/drmP.h:74, from include/drm/drm_modeset_helper.h:26, from include/drm/drm_atomic_helper.h:33, from drivers/gpu/drm/tilcdc/tilcdc_crtc.c:19: And thus, without this change, this patchset would inadvertantly change the behaviour of the tilcdc driver.
