The run-length encoding algorithm should compare 16-bit encoded pixel values instead of comparing raw pixel values. It allows pixels with similar but different colors to be encoded as repeat pixels, and thus potentially save USB bandwidth. Signed-off-by:

drm/panel: Changes for v3.20-rc1 This contains the long-awaited drm_bridge series that makes Chromebooks work for people. I had thought this would've been perfect by now, but then I go and build test it and the first thing it does is yell about a recursive dependency. I fixed that up because I was feeling bad for not getting around to look at this earlier. Biseds that there is new support for two more panels, a couple of fixup patches to the Sharp LQ101R1SX01 dual-channel DSI panel driver and a potential NULL pointer dereference fix. * tag 'drm/panel/for-3.20-rc1' of git://anongit.freedesktop.org/tegra/linux: (23 commits) drm/bridge: dw-hdmi: Adapt to bridge API change drm/sti: fixup for bridge interface drm/bridge: dw-hdmi: Fix return error path drm: Check the right variable when setting formats Documentation: bridge: Add documentation for ps8622 DT properties Documentation: devicetree: Add vendor prefix for parade Documentation: drm: bridge: move to video/bridge drm/bridge: ptn3460: use gpiod interface drm/bridge: ptn3460: probe connector at the end of bridge attach drm/bridge: ptn3460: support drm_panel drm/exynos: dp: support drm_bridge drm/bridge: ptn3460: Convert to I2C driver model drm/bridge: make bridge registration independent of drm flow drm/bridge: do not pass drm_bridge_funcs to drm_bridge_init drm/bridge: ptn3460: Few trivial cleanups drm/panel: simple: Add AVIC TM070DDH03 panel support of: Add vendor prefix for Shanghai AVIC Optoelectronics Co., Ltd. drm/panel: sharp: lq101r1sx01: Remove unneeded include drm/panel: sharp: lq101r1sx01: Respect power timings drm/panel: sharp: lq101r1sx01: Add delay after display on ...

So sti doesn't build because the bridge interfaces changes didn't catch up to its new DVO driver. Now I might just carry this patch, but I might just push the bridge pull into a side-pull until someone resolves it. So this might not be the right solution to the problem, so please figure it out and let me know ASAP. Signed-off-by:

Use drm_bridge helpers to modify the driver to support I2C driver model. Signed-off-by:

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:

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.
