drm/panel: Changes for v3.17-rc1 Panels can now be more finely controlled via .prepare() and .unprepare() callbacks in addition to .enable() and .disable(). New kerneldoc details what they are supposed to do and when they should be called. The simple panel driver gained support for a couple of new panels and it is now possible to specify additional delays during power up and power down sequences if panels require it. DSI devices can now advertise that they support non-continuous clock mode which will allow DSI host controllers to disable the high speed clock after transmissions to save power. * tag 'drm/panel/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux: (30 commits) drm/panel: simple: Use devm_gpiod_get_optional() drm/dsi: Replace upcasting macro by function drm/panel: ld9040: Replace upcasting macro by function drm/exynos: dp: Modify driver to support drm_panel drm/exynos: Move DP setup into commit() drm/panel: simple: Add AUO B133HTN01 panel support drm/panel: simple: Support delays in panel functions drm/panel: simple: Add proper definition for prepare and unprepare drm/panel: s6e8aa0: Add proper definition for prepare and unprepare drm/panel: ld9040: Add proper definition for prepare and unprepare drm/tegra: Add support for panel prepare and unprepare routines drm/exynos: dsi: Add support for panel prepare and unprepare routines drm/exynos: dpi: Add support for panel prepare and unprepare routines drm/panel: simple: Add dummy prepare and unprepare routines drm/panel: s6e8aa0: Add dummy prepare and unprepare routines drm/panel: ld9040: Add dummy prepare and unprepare routines drm/panel: Provide convenience wrapper for .get_modes() drm/panel: add .prepare() and .unprepare() functions drm/panel: simple: Remove simple-panel compatible drm/panel: simple: Add Innolux N116BGE panel support ...

Panels often require an initialization sequence that consists of three steps: a) powering up the panel, b) starting transmission of video data and c) enabling the panel (e.g. turn on backlight). This is usually necessary to avoid visual glitches at the beginning of video data transmission. Similarly, the shutdown sequence is typically done in three steps as well: a) disable the panel (e.g. turn off backlight), b) cease video data transmission and c) power down the panel. Currently drivers can only implement .enable() and .disable() functions, which is not enough to implement the above sequences. This commit adds a second pair of functions, .prepare() and .unprepare() to allow more fine-grained control over when the above steps are performed. Signed-off-by:

For each minor we allocate a sysfs device as minor->kdev. Currently, this is allocated and registered in drm_minor_register(). This makes it impossible to add sysfs-attributes to the device before it is registered. Therefore, they are not added atomically, nor can we move device_add() *after* ->load() is called. This patch makes minor->kdev available early, but only adds the device during minor-registration. Note that the registration is still called before ->load() as debugfs needs to be split, too. This will be fixed in follow-ups. Reviewed-by:

Instead of allocating the minor-index during registration, we now do this during allocation. This way, debug-messages between minor-allocation and minor-registration will now use the correct minor instead of 0. Same is done for unregistration vs. free, so debug-messages between device-shutdown and device-destruction show proper indices. Even though minor-indices are allocated early, we don't enable minor lookup early. Instead, we keep the entry set to NULL and replace it during registration / unregistration. This way, the index is allocated but lookup only works if registered. Reviewed-by:

Most of the new DRM management functions are nowadays in drm_stub.c.

The core files now look like this: drm_stub.c: Core management drm_drv.c: Ioctl dispatcher drm_ioctl.c: Actual ioctl backends drm_fops.c: Char-dev file-operations A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c.

If an active DRM-Master closes its device, we deauthenticate all clients on that master. However, if an inactive DRM-Master closes its device, we do nothing. This is quite inconsistent and breaks several scenarios: 1) If this was used as security mechanism, it fails horribly if a master closes a device while VT switched away. Furthermore, none of the few drivers using ->master_*() callbacks seems to require it, anyway. 2) If you spawn weston (or any other non-UMS compositor) in background while another compositor is active, both will get assigned to the same "drm_master" object. If the foreground compositor now exits, all clients of both the foreground AND background compositor will be de-authenticated leading to unexpected behavior. Stop this non-sense and keep clients authenticated. We don't do this when dropping DRM-Master (i.e., switching VTs) so don't do it on active-close either! Reviewed-by:

The drm_file->is_master field is redundant as it's equivalent to: drm_file->master && drm_file->master == drm_file->minor->master 1) "=>" Whenever we set drm_file->is_master, we also set: drm_file->minor->master = drm_file->master; Whenever we clear drm_file->is_master, we also call: drm_master_put(&drm_file->minor->master); which implicitly clears it to NULL. 2) "<=" minor->master cannot be set if it is non-NULL. Therefore, it stays as is unless a file drops it. If minor->master is NULL, it is only set by places that also adjust drm_file->is_master. Therefore, we can safely drop is_master and replace it by an inline helper that matches: drm_file->master && drm_file->master == drm_file->minor->master Reviewed-by:

Skip the "manual" pageflip completion checks via polling and guessing in the vblank handler radeon_crtc_handle_vblank() on asics which are known to reliably support hw pageflip completion irqs. Those pflip irqs are a more reliable and race-free method of handling pageflip completion detection, whereas the "classic" polling method has some small races in combination with dpm on, and with the reworked pageflip implementation since Linux 3.16. On old asics without pflip irqs, the classic method is used. On asics with known good pflip irqs, only pflip irqs are used by default, but a new module parameter "use_pflipirqs" allows to override this in case we encounter asics in the wild with unreliable or faulty pflip irqs. A module parameter of 0 allows to use the classic method only in such a case. A parameter of 1 allows to use both classic method and pflip irqs as additional band-aid to avoid some small races which could happen with the classic method alone. The setting 1 gives Linux 3.16 behaviour. Hw pflip irqs are available since R600. Tested on DCE-4, AMD Cedar - FirePro 2270. v2: agd5f: only enable pflip interrupts on DCE4+ as they are not reliable on older asics. Signed-off-by:
