drm/mali-dp: Rectify the width and height passed to rotmem_required()

drm/arm/malidp: Preserve LAYER_FORMAT contents when setting format

2018-08-24T11:06:42Z

[ Upstream commit ad7fda2e378f4356df621a39655f7c200b495d81 ] On some Mali-DP processors, the LAYER_FORMAT register contains fields other than the format. These bits were unconditionally cleared when setting the pixel format, whereas they should be preserved at their reset values.

drm: mali-dp: Enable Global SE interrupts mask for DP500

2018-08-24T11:06:42Z

[ Upstream commit 89610dc2c235e7b02bb9fba0ce247e12d4dde7cd ] In the situation that DE and SE aren’t shared the same interrupt number, the Global SE interrupts mask bit MASK_IRQ_EN in MASKIRQ must be set, or else other mask bits will not work and no SE interrupt will occur. This patch enables MASK_IRQ_EN for SE to fix this problem. Signed-off-by: Alison Wang Acked-by: Liviu Dudau Signed-off-by: Liviu Dudau Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

drm/arm/malidp: Ensure that the crtcs are shutdown before removing any encoder/connector

2018-08-24T11:06:42Z

[ Upstream commit 109c4d18e57445afcaf728b8716a69375a3daab2 ] One needs to ensure that the crtcs are shutdown so that the drm_crtc_state->connector_mask reflects that no connectors are currently active. Further, it reduces the reference count for each connector. This ensures that the connectors and encoders can be cleanly removed either when _unbind is called for the corresponding drivers or by drm_mode_config_cleanup(). We need drm_atomic_helper_shutdown() to be called before component_unbind_all() otherwise the connectors attached to the component device will have the wrong reference count value and will not be cleanly removed.

drm: mali-dp: Add YUV->RGB conversion support for video layers

2018-03-14T11:41:01Z

Internally Mali DP uses an RGB pipeline so video layers that support YUV input buffers need to convert the input data to RGB. The YUV buffers can have various encodings and this patch introduces support for BT.601, BT.709 and BT.2020 encodings, both limited and full ranges. This patch adds support for specifying the color encoding of the input buffers for the planes that are backed by the video layers and programs the YUV2RGB coefficients into hardware based on the selected encoding.

drm: mali-dp: Turn off CRTC vblank when removing module.

2018-03-14T11:38:03Z

When unbinding the mali-dp driver the drm_vblank_cleanup() function warns us that the vblanks are still enabled. Fix that by calling drm_crtc_vblank_off() in the malidp_unbind() function. Signed-off-by: Liviu Dudau

drm: arm: malidp: Use drm_atomic_helper_shutdown() to disable planes on removal

2018-03-14T11:38:03Z

The plane cleanup handler currently calls drm_plane_helper_disable(), which is a legacy helper function. Replace it with a call to drm_atomic_helper_shutdown() at removal time. Signed-off-by: Laurent Pinchart Signed-off-by: Liviu Dudau

drm: arm: malidp: Don't destroy planes manually in error handlers

2018-03-14T11:38:02Z

The top-level error handler calls drm_mode_config_cleanup() which will destroy all planes. There's no need to destroy them manually in lower error handlers. As plane cleanup is now handled entirely by drm_mode_config_cleanup(), we must ensure that the plane .destroy() handler frees allocated memory for the plane object that was freed by malidp_de_planes_destroy(). Do so by replacing the call to devm_kfree() in the .destroy() handler by kfree(). devm_kfree() is currently a no-op as the plane memory is allocated with kzalloc(), not devm_kzalloc().

drm/mali-dp: Fix malidp_atomic_commit_hw_done() for event sending.

2018-03-14T11:38:02Z

Mali DP hardware has a 'go' bit (config_valid) for making the new scene parameters active at the next page flip. The problem with the current code is that the driver first sets this bit and then proceeds to wait for confirmation from the hardware that the configuration has been updated before arming the vblank event. As config_valid is actually asserted by the hardware after the vblank event, during the prefetch phase, when we get to arming the vblank event we are going to send it at the next vblank, in effect halving the vblank rate from the userspace perspective. Fix it by sending the userspace event from the IRQ handler, when we handle the config_valid interrupt, which syncs with the time when the hardware is active with the new parameters.

drm/arm/malidp: Disable pixel alpha blending for colors that do not have alpha

2018-03-14T11:38:02Z

Mali dp needs to disable pixel alpha blending (use layer alpha blending) to display color formats that do not contain alpha bits per pixel This patch depends on: "[PATCH v2 01/19] drm/fourcc: Add a alpha field to drm_format_info" Signed-off-by: Ayan Kumar Halder Signed-off-by: Liviu Dudau
