2013-06-22gpu: host1x: Rework CPU syncpoint incrementArto Merilainen1-2/+1
This patch merges host1x_syncpt_cpu_incr to host1x_syncpt_incr() as they are in practise doing the same thing. host1x_syncpt_incr() is also modified to return error codes. User space interface is modified accordingly to pass return values.

2013-06-22gpu: host1x: Fix client_managed typeArto Merilainen1-1/+1
client_managed field in syncpoint structure was defined as an integer. The field holds, however, only a boolean value. This patch modifies the type to boolean.

2013-06-22drm/tegra: Remove DRIVER_BUS_PLATFORM from driver_featuresLaurent Pinchart1-1/+1
DRIVER_BUS_PLATFORM is not a DRM driver feature flag, it must not be set in the driver's driver_features field. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2013-06-22drm/tegra: Fix return valueThierry Reding1-1/+1
Return NULL instead of 0 in host1x_bo_lookup(). Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2013-05-25drm/tegra: fix error return code in gr2d_submit()Wei Yongjun1-2/+6
Fix to return -ENOENT in the host1x_bo lookup error handling case instead of 0, as done elsewhere in this function. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-05-25drm/tegra: fix missing unlock on errorWei Yongjun1-0/+2
Add the missing unlock before return from function host1x_drm_init() and host1x_drm_exit() in the error handling case. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-05-25drm/tegra: Honor pixel-format changesThierry Reding1-0/+2
When using a base mode-set, honor changes in pixel-format since the core doesn't explicitly check for them as long as they use the same depth. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-05-25drm/tegra: Explicitly set irq_enabledThierry Reding1-0/+7
Since the Tegra DRM driver doesn't use the drm_irq_install() helper, the irq_enabled flag needs to be set manually in order to make functionality such as the DRM_IOCTL_WAIT_VBLANK work properly. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-05-25drm/tegra: Don't disable unused planesThierry Reding1-0/+3
When a plane isn't in use it isn't attached to a CRTC and therefore the DC registers aren't available for programming. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-05-18drivers/gpu/host1x/drm: don't check resource with devm_ioremap_resourceWolfram Sang1-5/+0
devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-04-22drm/tegra: don't depend on OFStephen Warren1-1/+1
ARCH_TEGRA always enabled OF, so there's no need for any driver to depend on it. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>

2013-04-22gpu: host1x: drm: Add memory manager and fbArto Merilainen7-34/+699
This patch introduces a memory manager for tegra drm and moves existing parts to use it. As cma framebuffer helpers can no more be used, this patch adds also a separate framebuffer driver for tegra.
