During system suspend, we: 1. Cache a duplicate of the current DRM atomic state, which calls hooks to duplicate our internal states. 2. Call hooks to disable all functionalities. 3. System suspended. During resume, we attempt to restore the cached state. However, our interal states are now stale, since step 1 was done before step 2. i.e. our cached state does not reflect the disabled nature of things. This change resolves that by destroying all relevant states to reflect the actual state during resume. Signed-off-by:

This was missed in the previous fake sink change. The fake sink allows us to enable a pipe with a disconnected display. We shouldn't report it as connected. Signed-off-by:

A previous change moved link_disconnect_sink after dpcd read, this causes the sink count to be overwritten which in turn causes another detection to be triggered in the short pulse handler, which brings down the display. Signed-off-by:

Leo (Sunpeng) Li authored
To conform to DRM's new API, we should not be accessing a DRM object's internal state directly. Rather, the DRM for_each_old/new_* iterators, and drm_atomic_get_old/new_* interface should be used. This is an ongoing process. For now, update the DRM-facing atomic functions, where the atomic state object is given. Reviewed-by:

Use the correct for_each_new/old_* iterators instead of for_each_* The following functions were considered: amdgpu_dm_find_first_crtc_matching_connector: use for_each_new - Old from_state_var flag was always choosing the new state amdgpu_dm_display_resume: use for_each_new - drm_atomic_helper_duplicate_state is called during suspend to cache the state - It sets 'state' within the state triplet to 'new_state' amdgpu_dm_commit_planes: use for_each_old - Called after the state was swapped (via atomic commit tail) amdgpu_dm_atomic_commit: use for_each_new - Called before the state is swapped amdgpu_dm_atomic_commit_tail: use for_each_old - Called after the state was swapped dm_update_crtcs_state: use for_each_new - Called before the state is swapped (via atomic check) amdgpu_dm_atomic_check: use for_each_new - Called before the state is swapped v2: Split out typo fixes to a new patch. v3: Say "functions considered" instead of "affected functions". The latter implies that changes are made to each. [airlied: squashed with my hacks] Reviewed-by: -

Initially we configured the PAD_CTRL1 register at probe/bind time. However it seems the HDMI controller will modify some of the bits in this register by itself. On the A10 it is particularly annoying as it toggles the output invert bits, which inverts the colors on the display output. The U-boot driver this driver is based on sets this register twice, though it seems it's only needed for actual display output. Hence we move it to the mode_set function. Signed-off-by:

While debugging inverted color from the HDMI output on the A10, I found that the lowest 3 bits were set. These were cleared on A20 boards that had normal display output. By manually toggling these bits the mapping of the color components to these bits was found. While these are not used anywhere, it would be nice to document them somewhere. Signed-off-by:

Many of the backend's layer configuration registers have undefined default values. This poses a risk as we use regmap_update_bits in some places, and don't overwrite the whole register. At probe/bind time we explicitly clear all the control registers by writing 0 to them. This patch adds a more detailed explanation on why we're doing this. Signed-off-by:

Commit 4636ce93 ("drm/fb-cma-helper: Add drm_fb_cma_get_gem_addr()") adds a new helper, which covers fetching a drm_framebuffer's GEM object and calculating the buffer address for a given plane. This patch uses this helper to replace our own open coded version of the same function. Signed-off-by:

The backend has various clocks and reset controls that need to be enabled and deasserted before register access is possible. Move the creation of the regmap to after the clocks and reset controls have been configured where it makes more sense. Signed-off-by:
