|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into drm-fixes Three changes for the Armada DRM driver: 1. Add back the flags which tell the DRM core that we can do vblank. This was removed in error during the recent restructuring, and came to light while trying textured Xv rendering. 2. Fixing a refcount leak with Xv overlay. 3. As per recent discussion, the drm_vblank_pre_modeset() calls can cause deadlock with other changes to generic code. This change prevents those deadlocks by switching to the drm_crtc_vblank_*() calls instead. * 'drm-armada-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: drm/armada: convert to use vblank_on/off calls drm/armada: fix page_flip refcounting leak drm/armada: add IRQ support back

* | drm: add driver->set_busid() callbackDavid Herrmann2014-09-101-0/+1
|/ | | | | | | | | | | | | | One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

* drm/armada: move variant initialisation to CRTC initRussell King2014-07-031-4/+0Star
| | | | | | | | Move the variant initialisation entirely to the CRTC init function - the variant support is really about the CRTC properties than the whole system, and we want to treat each CRTC individually when we support DT. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | Use the number of CRTCs registered to size the vblank arrays rather than our own count. Number CRTCs using this as well. This permits us to register CRTCs as components in the near future rather than as part of a single device. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used in a few places. I suspect its usage has been spread by copy & paste rather than anything else.

* drm: pass the irq explicitly to drm_irq_installDaniel Vetter2014-04-231-1/+1
| | | | | | | | | | | | | Unfortunately this requires a drm-wide change, and I didn't see a sane way around that. Luckily it's fairly simple, we just need to inline the respective get_irq implementation from either drm_pci.c or drm_platform.c. With that we can now also remove drm_dev_to_irq from drm_irq.c.

|/ | | | | | | | | | | | | | | git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next This adds support for the Armada 510 display subsystem found on the Marvell Dove devices. This IP is re-used across several different Marvell SoCs with various tweaks, and this driver has been structured to allow the other IPs to re-use the bulk of this code; further work in this area is expected from interested parties. This has been extensively tested on the SolidRun Cubox platform and appears to work well there. [airlied: update for api changes merged previous to this]

* DRM: Armada: Add Armada DRM driverRussell King2013-10-121-0/+380
This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.
