drm/arm: hdlcd: remove unused variables

2017-06-21T09:51:26+00:00

The last rework left behind two unused variables: drm/arm/hdlcd_crtc.c: In function 'hdlcd_plane_atomic_update': drm/arm/hdlcd_crtc.c:264:13: warning: unused variable 'src_y' [-Wunused-variable] drm/arm/hdlcd_crtc.c:264:6: warning: unused variable 'src_x' [-Wunused-variable] This removes them.

drm/arm: hdlcd: Use CMA helper for plane buffer address calculation

2017-06-21T09:30:01+00:00

CMA has gained a recent helper function for calculating the start of the plane buffer's physical address. Use that instead of the hand rolled version. Signed-off-by: Liviu Dudau

drm/arm: hdlcd: Set the CRTC's port before binding the encoder.

2017-06-21T09:30:01+00:00

The component-based encoder(s) used by HDLCD expect the CRTC port to be set before binding in order to find the right endpoint. Without this patch, the TDA19988 encoder driver prints a warning "Falling back to first CRTC". Signed-off-by: Liviu Dudau

drm/mali-dp: Check PM status when sharing interrupt lines

2017-06-16T10:56:46+00:00

If an instance of Mali DP hardware shares the interrupt line with another hardware (usually another instance of the Mali DP) its interrupt handler can get called when the device is suspended. Check the PM status before making access to the hardware registers to avoid deadlocks. Signed-off-by: Liviu Dudau

drm/arm: malidp: Use crtc->mode_valid() callback

2017-06-16T10:56:46+00:00

Now that we have a callback to check if crtc supports a given mode we can use it in malidp so that we restrict the number of probbed modes to the ones we can actually display. Also, remove the mode_fixup() callback as this is no longer needed because mode_valid() will be called before.

drm/hdlcd|mali: Drop drm_vblank_cleanup

2017-06-01T06:02:14+00:00

IRQs are properly shut down, so it almost works as race-free shutdown. Except the irq is stopped after the vblank stuff, so boom anyway. Proper way would be to call drm_atomic_helper_shutdown before any of the kms things gets stopped. So no harm in removing the drm_vblank_cleanup here really. Same story for both hdlcd and mali. v2: Move misplaced malidp hunk to this patch (Liviu).

drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPI

2017-05-22T07:49:48+00:00

Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI as a convenience. Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up through the atomic API, but realizing that userspace is likely to take shortcuts and assume that the enum values are what is sent over the wire. As a result these defines are provided purely as a convenience to userspace applications. Changes since v3: - Switched away from past tense in comments - Add define name change to previously mis-spelled DRM_REFLECT_X comment - Improved the comment for the DRM_MODE_REFLECT_ comment Changes since v2: - Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_ - Fix compilation errors - Changed comment formatting - Deduplicated comment lines - Clarified DRM_MODE_PROP_REFLECT_ comment Changes since v1: - Moved defines from drm.h to drm_mode.h - Changed define prefix from DRM_ to DRM_MODE_PROP_ - Updated uses of the defines to the new prefix - Removed include from drm_rect.c - Stopped using the BIT() macro Signed-off-by: Robert Foss Reviewed-by: Emil Velikov Reviewed-by: Sinclair Yeh Acked-by: Liviu Dudau Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170519205017.23307-2-robert.foss@collabora.com
