2017-08-08drm: Handle properties in the core for atomic driversDaniel Vetter10-53/+161
The reason behind the original indirection through the helper functions was to allow existing drivers to overwrite how they handle properties. For example when a vendor-specific userspace had expectations that didn't match atomic. That seemed likely, since atomic is standardizing a _lot_ more of the behaviour of a kms driver. But 20 drivers later there's no such need at all. Worse, this forces all drivers to hook up the default behaviour, breaking userspace if they forget to do that. And it forces us to export a bunch of core function just for those helpers. And finally, these helpers are the last places using drm_atomic_legacy_backoff() and the implicit acquire_ctx. This patch here just implements the new behaviour and updates the docs. Follow-up patches will garbage-collect all the dead code. v2: Fixup docs even better! v3: Make it actually work ... v4: Drop the uses_atomic_modeset() checks from the previous patch again, since they're now moved up in the callchain.

2017-08-08drm: Don't update property values for atomic driversDaniel Vetter5-27/+33
Atomic drivers only use the property value store for immutable (i.e. can't be set by userspace, but the kernel can still adjust it) properties. The only tricky part is the removal of the update in drm_atomic_helper_update_legacy_modeset_state(). This was added in commit 8c10342cb48f3140d9abeadcfd2fa6625d447282 (tag: topic/drm-misc-2015-07-28) Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Mon Jul 27 13:24:29 2015 +0200 drm/atomic: Update legacy DPMS state during modesets, v3. by copying it from the i915 code, where it was originally added in commit 68d3472047a572936551f8ff0b6f4016c5a1fdef Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Sep 6 22:08:35 2012 +0200 drm/i915: update dpms property in set_mode for the legacy modeset code. The reason we needed this hack was that i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of the newer-ish drm_drv_uses_atomic_modeset(), which avoids such troubles. With the correct feature checks this isn't needed anymore at all. Also make sure that drivers don't accidentally get this wrong by making the exported version of drm_object_property_get_value() only work for legacy drivers.

2017-08-08drm: bridge: synopsys/dw-hdmi: Provide default configuration function for ↵Jose Abreu1-0/+1
HDMI 2.0 PHY Currently HDMI 2.0 PHYs do not have a default configuration function. As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D PHYs we can provide the same default configuration function for both and still let user overwrite this with custom configuration function if needed. If, for some reason, the PHY is custom or has a register different register layout then custom configuration function *must* be provided in order for the system to work correctly. As we prefer the pdata provided configuration function over the internal one this change will not make any impact in custom platforms.

The fbdev subsystem has a place for physical dimensions (width and height in mm) that is readable by userspace. Since DRM also knows these dimensions, pass this information to the fbdev device. This has to be done in drm_setup_crtcs_fb() instead of drm_setup_crtcs() because fb_helper->fbdev may be NULL in drm_setup_crtcs().
