Ajay Kumar authored
Currently, third party bridge drivers(ptn3460) are dependent on the corresponding encoder driver init, since bridge driver needs a drm_device pointer to finish drm initializations. The encoder driver passes the drm_device pointer to the bridge driver. Because of this dependency, third party drivers like ptn3460 doesn't adhere to the driver model. In this patch, we reframe the bridge registration framework so that bridge initialization is split into 2 steps, and bridge registration happens independent of drm flow: --Step 1: gather all the bridge settings independent of drm and add the bridge onto a global list of bridges. --Step 2: when the encoder driver is probed, call drm_bridge_attach for the corresponding bridge so that the bridge receives drm_device pointer and continues with connector and other drm initializations. The old set of bridge helpers are removed, and a set of new helpers are added to accomplish the 2 step initialization. The bridge devices register themselves onto global list of bridges when they get probed by calling "drm_bridge_add". The parent encoder driver waits till the bridge is available in the lookup table(by calling "of_drm_find_bridge") and then continues with its initialization. The encoder driver should also call "drm_bridge_attach" to pass on the drm_device to the bridge object. drm_bridge_attach inturn calls "bridge->funcs->attach" so that bridge can continue with drm related initializations.

Assign the pointer to bridge ops structure(drm_bridge_funcs) in the bridge driver itself, instead of passing it to drm_bridge_init. This will allow bridge driver developer to pack bridge private information inside the bridge object and pass only the drm-relevant information to drm_bridge_init. Signed-off-by:

This patch does the following changes: -- Use usleep_range instead of udelay. -- Remove driver_private member from ptn3460 structure. -- Make all possible functions and structures static. -- Use dev_err for non-DRM errors. -- Arrange header files alphabetically. -- s/edid/EDID in all error messages.

Before shutting down the display using the DCS display_off command, wait for 4 frames according to the datasheet. Furthermore, after enabling the power supply, the supply voltage needs around 10 ms to settle. After that, another 120 ms is required before a DCS exit_sleep_mode command can be sent. While at it, no longer send the DCS soft_reset command. This is totally unnecessary because we've just powered up the display, hence it will be in a reset state already. Signed-off-by: -

After switching the display on (using the DCS display_on command), wait for 6 frames (100ms at 60 Hz) to give the display more time to prepare. Failing to do this results in the panel not initializing properly in a large number of cases. Signed-off-by: -

This patch adds support for the GiantPlus GPG48273QS5 4.3" WQVGA TFT LCD panel to the simple-panel driver. This panel is connected via a parallel bus and uses both HSYNC and VSYNC, whose lengths are unfortunately not clearly defined. The datasheet only specifies the front- and backporch length, but the timing diagram suggests that both sync signals should be asserted for exactly one clock cycle. Signed-off-by:

drm/tegra: Changes for v3.20-rc1 The biggest part of these changes is the conversion to atomic mode- setting. A lot of cleanup and demidlayering was required before the conversion, with the result being a whole lot of changes. Besides the atomic mode-setting support, the host1x bus now has the proper infrastructure to support suspend/resume for child devices. Finally, a couple of smaller cleanup patches round things off. * tag 'drm/tegra/for-3.20-rc1' of git://anongit.freedesktop.org/tegra/linux: (54 commits) drm/tegra: Use correct relocation target offsets drm/tegra: Add minimal power management drm/tegra: dc: Unify enabling the display controller drm/tegra: Track tiling and format in plane state drm/tegra: Track active planes in CRTC state drm/tegra: Remove unused ->mode_fixup() callbacks drm/tegra: Atomic conversion, phase 3, step 3 drm/tegra: Atomic conversion, phase 3, step 2 drm/tegra: dc: Use atomic clock state in modeset drm/tegra: sor: Implement ->atomic_check() drm/tegra: hdmi: Implement ->atomic_check() drm/tegra: dsi: Implement ->atomic_check() drm/tegra: rgb: Implement ->atomic_check() drm/tegra: dc: Store clock setup in atomic state drm/tegra: Atomic conversion, phase 3, step 1 drm/tegra: Atomic conversion, phase 2 drm/tegra: Atomic conversion, phase 1 drm/tegra: dc: Do not needlessly deassert reset drm/tegra: Output cleanup functions cannot fail drm/tegra: Remove remnants of the output midlayer ...

Previously output drivers would enable continuous display mode and power up the display controller at various points during the initialization. This is suboptimal because it accesses display controller registers in output drivers and duplicates a bit of code. Move this code into the display controller driver and enable the display controller as the final step of the ->mode_set_nofb() implementation. Signed-off-by: -

Replace drm_crtc_helper_set_config() by drm_atomic_helper_set_config(). All drivers have now been converted to use ->atomic_check() to set the atomic state, therefore the atomic mode setting helpers can be used. Signed-off-by: -

All clock state is now stored in the display controller's atomic state, so the output drivers no longer need to call back into the display controller driver to set up the clock. This is also required to make sure no hardware changes are made before validating a configuration. Signed-off-by: -

The implementation of the ->atomic_check() callback precomputes all parameters to check if the given configuration can be applied. If so the precomputed values are stored in the atomic state object for the encoder and applied during modeset. In that way the modeset no longer needs to perform any checking but simply program values into registers. Signed-off-by: -

Implement initial atomic state handling. Hook up the CRTCs, planes' and connectors' ->atomic_destroy_state() callback to ensure that the atomic state objects don't leak. Furthermore the CRTC now implements the ->mode_set_nofb() callback that is used by new helpers to implement ->mode_set() and ->mode_set_base(). These new helpers also make use of the new plane helper functions which the driver now provides. Signed-off-by: -
