There are some hardware settings changed, between MT8173 & MT2701: DISP_OVL address offset changed, color format definition changed. DISP_RDMA fifo size changed. DISP_COLOR offset changed. MIPI_TX pll setting changed. And add prefix for mtk_ddp_main & mtk_ddp_ext & mutex_mod. Signed-off-by: YT Shen <yt.shen@mediatek.com> Acked-by: CK Hu <ck.hu@mediatek.com>
2017-02-21drm: mediatek: use vblank hooks in struct drm_crtc_funcsShawn Guo1-3/+0
The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead.

2017-02-07drm: remove drm_vblank_no_hw_counter assignment from driver codeShawn Guo1-1/+0
Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now.

2016-12-13drm/mediatek: don't use drm_put_devDaniel Vetter1-1/+2
fsl is already fully demidlayered in the probe function, but for convenience stuck with drm_put_dev. Call the unregister/unref parts separately, to make sure this driver works correct.

No one outside of drm_irq.c should ever need this. The correct way to implement get_vblank_count for hw lacking a vblank counter is drm_vblank_no_hw_counter. Fix this up in mtk, which is the only offender left over.

2016-10-17drm: Add reference counting to drm_atomic_stateChris Wilson1-1/+2
drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics). This is even more beneficial when the lifetime of the state becomes more convoluted than being passed to a single worker thread for the commit. v2: Double check !intel atomic_commit functions for missing gets v3: Update kerneldocs Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: dri-devel@lists.freedesktop.org Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20161014121833.439-27-chris@chris-wilson.co.uk

2016-08-29drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying1-2/+4
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-08-08drm/mediatek: Fix mtk_atomic_complete for runtime_pmBibby Hsieh1-1/+16
To properly implement atomic w/ runtime pm, we move drm_atomic_helper_commit_modeset_enables() above drm_atomic_helper_commit_planes() to ensure CRTCs are enabled before modifying plane registers, and set active_only to true to filter out plane update notifications when the CRTC is disabled. According to the document from linux kernel: Set the active_only parameters to true in order not to receive plane update notifications related to a disabled CRTC. This avoids the need to manually ignore plane updates in driver code when the driver and/or hardware can't or just don't need to deal with updates on disabled CRTCs, for example when supporting runtime PM.

2016-06-21drm/mediatek: Remove redundant calls to drm_connector_register_all()Chris Wilson1-7/+0
Up to now, the recommendation was for drivers to call drm_dev_register() followed by drm_connector_register_all(). Now that drm_connector_register() is safe against multiple invocations, we can move drm_connector_register_all() to drm_dev_register() and not suffer from any backwards compatibility issues with drivers not following the more rigorous init ordering.
