2015-06-12drm: omapdrm: Switch connector DPMS to atomic helpersLaurent Pinchart
The atomic connector DPMS helper implements the connector DPMS operation using atomic commit, removing the need for DPMS helper operations on CRTCs and encoders. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2015-06-12drm: omapdrm: Handle primary plane config through atomic plane opsLaurent Pinchart
Use the new CRTC atomic transitional helpers drm_helper_crtc_mode_set() and drm_helper_crtc_mode_set_base() to implement the CRTC .mode_set and .mode_set_base operations. This delegates primary plane configuration to the plane .atomic_update and .atomic_disable operations, removing duplicate code from the CRTC implementation.

2015-06-12drm: omapdrm: Implement planes atomic operationsLaurent Pinchart
Implement the CRTC .atomic_begin() and .atomic_flush() operations, the plane .atomic_check(), .atomic_update() and operations, and use the transitional atomic helpers to implement the plane update and disable operations on top of the new atomic operations.

2015-06-12drm: omapdrm: Wire up atomic state object scaffoldingLaurent Pinchart
Hook up the default .reset(), .atomic_duplicate_state() and .atomic_free_state() helpers to ensure that state objects are properly created and destroyed, and call drm_mode_config_reset() at init time to create the initial state objects. Framebuffer reference count also gets maintained automatically by the transitional helpers except for the legacy page flip operation. Maintain it explicitly there.

2015-06-12drm: omapdrm: Rework CRTC enable/disable for atomic updatesLaurent Pinchart
When using atomic updates the CRTC .enable() and .disable() helper operations are preferred over the (then legacy) .prepare() and .commit() operations. Implement .enable() and rework .disable() to not depend on DPMS, easing DPMS removal later on.

2015-06-12drm: omapdrm: Rename CRTC DSS operations with an omap_crtc_dss_ prefixLaurent Pinchart

Rename them to omap_crtc_dss_*, as well as the other DSS operations for consistency.

2015-06-12drm: omapdrm: Fix page flip race with CRTC disableLaurent Pinchart
We can't rely on crtc->primary->fb in the page flip worker, as a racing CRTC disable (due for instance to an explicit framebuffer deletion from userspace) would set that field to NULL before the worker gets a change to run. Store the framebuffer queued for page flip in a new field of omap_crtc instead, and hold a reference to it.

2015-06-12drm: omapdrm: Turn vblank on/off when enabling/disabling CRTCLaurent Pinchart
The DRM core vblank handling mechanism requires drivers to forcefully turn vblank reporting off when disabling the CRTC, and to restore the vblank reporting status when enabling the CRTC. Implement this using the drm_crtc_vblank_on/off helpers. When disabling vblank we must first wait for page flips to complete, so implement page flip completion wait as well. Finally, drm_crtc_vblank_off() must be called at startup to synchronize the state of the vblank core code with the hardware, which is initially disabled. An interesting side effect is that the .disable_vblank() operation will now be called for the first time with the CRTC disabled and the DISPC runtime suspended. The dispc_runtime_get() call in .disable_vblank() is supposed to take care of that, but the operation is called with a spinlock held, which prevents it from sleeping. To fix that move DISPC runtime PM handling out of the vblank operations to the CRTC code, ensuring that the display controller will always be powered when enabling or disabling vblank interrupts.

2015-06-12drm: omapdrm: Rework page flip handlingLaurent Pinchart
To implement proper vblank control the driver will need to wait for page flip completion before disabling the vblank interrupt. This is made complex by the page flip implementation which queues and submits page flips to the hardware in two separate steps between which DRM locks are released. We thus need to avoid waiting on a page flip that has been queued but not submitted as submission and wait are covered by the same lock. Rework page flip handling as a first step by splitting the flip_pending boolean variable into an enumerated state and moving between states based on flip queue, submission and completion. The CANCELLED state will be used in a second step. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-06-12drm: omapdrm: Cancel pending page flips when closing deviceLaurent Pinchart
Pending page flips must be cancelled when closing the device, otherwise their completion at next vblank will result in nasty effects, including possible oopses due to resources required to complete the page flip being freed.

2015-06-12drm: omapdrm: Simplify IRQ registrationLaurent Pinchart
The omapdrm can't use drm_irq_install() and drm_irq_uninstall() as it delegates IRQ handling to the omapdss driver. However, the code still declares IRQ-related operations used by the DRM IRQ helpers, and calls them indirectly. Simplify the implementation by calling the functions directly or inlining them. The irq_enabled checks can then also be simplified as the call stacks guarantees that omap_drm_irq_install() and omap_drm_irq_uninstall() will never run concurrently.

2015-06-12drm: omapdrm: Rename omap_crtc page flip-related fieldsLaurent Pinchart

2015-06-12drm: omapdrm: Apply settings synchronouslyLaurent Pinchart
The omapdrm driver implements a mechanism to apply new settings (due to plane update, plane disable, plane property set, CRTC mode set or CRTC DPMS) asynchronously. While this improves performance, it adds a level of complexity that makes transition to the atomic update API close to impossible. Furthermore the atomic update API requires part of the apply operations to be synchronous (such as pinning the framebuffers), so the current implementation needs to be changed. Simplify the CRTC and plane code by making updates synchronous to prepare for the switch to the atomic update API. Asynchronous update will be implemented in a second step.
