The patch adds parallel output interface to FIMD device driver. It also restores support for panels initialized by boot loader, but without proper kernel driver. Driver uses video interface bindings to find connected panel. It uses drm_panel interface to interact with the panel. Signed-off-by:

The patch corrects porch calculation. It should be calculated as a difference between adjacent respective fields of drm_display_mode. Signed-off-by:

KMS poll init helper should be run when connectors are created, otherwise it will not schedule connection detector. Signed-off-by:

In case fbdev is initialized before any output is connected, fb resolution defaults to 1024x768. After that any output with bigger resolution is ignored and fbdev is not displayed. The patch postpones fbdev initialization to avoid such situation. Signed-off-by:

This patch returns error in case of using APB PHY. Exynos5420 SoC and maybe later would use APB PHY instead of I2C PHY so such case should be considered. Signed-off-by:

This path removes the exynos_drm_connector code since it was just passing hooks through display_ops. The individual device drivers are now responsible for implementing drm_connector directly. Signed-off-by:

This patch implements drm_connector in the hdmi driver directly, instead of using exynos_drm_connector. Signed-off-by:
-
Sean Paul authored
This creates a new display hook called create_connector. The purpose is to allow the display driver to create its own drm_connector instead of using the exynos_drm_connector. This moves things closer to completely removing the exynos_drm_connector abstraction. Signed-off-by:

This patch removes all of the suspend/resume logic from the individual drivers and consolidates it in drm_drv. This consolidation reduces the number of functions which enable/disable the hardware to just one -- the dpms callback. This ensures that we always power up/down in a consistent manner. Signed-off-by:
-
Sean Paul authored
This patch separates the fimd_activate function into poweron/poweroff functions to be more consistent with the other drivers in exynos drm. It also properly cleans up after failures in poweron. The functions have also been shuffled around such that they are all in the same spot in the file and poweron/poweroff can be called from the dpms function. Signed-off-by:

This patch moves the exynos_drm_display implementation from fimd into the dp driver. This will allow for tighter integration of the dp driver into the exynos drm driver. Signed-off-by:

This patch moves the code from video/ to drm/. This is required the DP driver needs to power on/off in the correct order in relation to fimd. This will also allow the DP driver to participate in drm modeset as well as provide accurate connection detection and edid. Signed-off-by:

This patch removes a few fimd_context members which are either entirely unused or unneeded. Signed-off-by:

Sean Paul authored
This patch uses the mode passed into mode_set to configure fimd instead of directly using the panel from context. This will allow us to move the exynos_drm_display implementation out of fimd, where it doesn't belong. Signed-off-by:

This patch adds a new manager callback for mode_fixup and pipes it through exynos_drm_crtc. This will allow the manager drivers to alter the mode during modeset. Signed-off-by:
-
Sean Paul authored
This patch adds a mode_set callback to the manager operations which sets the crtc's current mode to the manager driver. This will allow the fimd driver to set its mode using values from drm, instead of the dt. Signed-off-by:

This patch moves the code which disables unused crtc planes from the encoder to the crtc. Since there is a 1:1 encoder/crtc mapping in exynos, the only valid crtc change the pre-existing code could catch is disconnecting an active crtc from the encoder. Thus it is functionally equivalent to just disable all planes attached to a crtc when the crtc is disabled. Signed-off-by:

This patch changes the manual copying of mode to adjusted_mode in mode_fixup to use drm_mode_copy instead of handling things manually. Signed-off-by:

This patch trims exynos_drm_hdmi out of the driver. The reason it existed in the first place was to make up for the mixture of display/overlay/manager ops being spread across hdmi and mixer. With that code now rationalized, mixer and hdmi map directly to exynos_drm_crtc and exynos_drm_encoder, respectively. Since there is a 1:1 mapping, we no longer need this layer. Signed-off-by:

The i2c client was previously being passed into the hdmi driver via a dedicated i2c driver, and then a global variable. This patch removes all of that and just uses the device tree to get the i2c_client. This patch also properly references the client so we don't lose it before we're done with it. Signed-off-by:

This patch splits display and manager from subdrv. The result is that crtc functions can directly call into manager callbacks and encoder functions can directly call into display callbacks. This will allow us to remove the exynos_drm_hdmi shim and support mixer/hdmi & fimd/dp with common code. Signed-off-by:

Change all instances of possible_crtcs in the exynos drm driver to be unsigned long. This matches the type used in the drm layer. Signed-off-by:

This patch removes the dpms state tracking in encoder. This state is at best confusing and at worst incorrect since the display drivers can turn on and off without propagating the value. Signed-off-by:
-
Sean Paul authored
This patch renames the display_op power_on to dpms to accurately reflect what the function does. The side-effect of this patch is that the new hdmi dpms callback is now invoked twice in the dpms path. This is safe and will be dealt with when the exynos_drm shim goes away. Signed-off-by:

Sean Paul authored
This patch removes the call from encoder dpms into connector dpms (which will then call back into encoder dpms through the helper function). The callback is likely to keep connector->dpms in the right state when initiating dpms from crtc or encoder, but this isn't the right way to do it. This patch is the first step towards rationalizing power management in the exynos drm driver. Signed-off-by:

This patch removes the apply() manager callback in favor of putting the relevant commits in the individual drivers. This will mitigate some of the difference between the suspend/resume path and the dpms path Signed-off-by:

This patch changes the manager ops callbacks from accepting the subdrv device pointer to taking a pointer to the manager. This will allow us to move closer to decoupling manager/display from subdrv, and subsequently decoupling the crtc/plane from the encoder. Signed-off-by:

This patch implements the initialize callback in the hdmi and mixer manager. This allows us to get rid of drm_dev in the drm_hdmi level and track it in the mixer and hdmi drivers. This is one of the things holding back the complete removal of the drm_hdmi layer. Signed-off-by:

This patch implements the intitialize manager op in fimd. This will allow us to keep track of drm_dev in context instead of using subdev, which in turn makes it easier to remove subdev from fimd. Signed-off-by:

This patch adds an initialize function to the manager and display operations. This allows them to keep track of drm_device in their local context, as well as adds an initialization hook right after the encoder is created. Signed-off-by:

This patch merges overlay_ops into manager_ops. In all cases, overlay_ops is implemented in the same place as manager ops, it doesn't serve a functional purpose, and doesn't make things more clear. Signed-off-by:
