As a result of atomic DPMS support, the various prepare/commit hooks get called in a way that msm dislikes. We were expecting prepare/commit to bracket a modeset, which is no longer the case. This was needed to hold various extra clk's (such as interface clks) on while we are touching registers, and in the case of mdp4 holding vblank enabled. The most straightforward way to deal with this, since we already have our own atomic_commit(), is to just handle prepare/commit internally to the driver (with some additional vfuncs for mdp4 vs mdp5), and switch everything over to instead use the new enable/disable hooks. It doesn't really change too much, despite the code motion. What used to be in the encoder/crtc dpms() fxns is split out into enable/disable. We should be able to drop our own enable-state tracking, as the atomic helpers should do this for us. But keeping that for the short term for extra debugging as atomic stablizes. Signed-off-by: -

The shmobile drm driver selects BACKLIGHT_CLASS_DEVICE as of 0a5a5499 "drm: shmobile: Add dependency on BACKLIGHT_CLASS_DEVICE", but that option in turn depends on BACKLIGHT_LCD_SUPPORT, so we actually have to select both, or alternatively use 'depends on BACKLIGHT_CLASS_DEVICE'. Further, the driver uses FB_SH_MOBILE_MERAM if that is enabled, but this breaks if MERAM is a module while the DRM driver is built-in. To solve this, add a dependency on "FB_SH_MOBILE_MERAM || !FB_SH_MOBILE_MERAM", which forces DRM_SHMOBILE to be a module if FB_SH_MOBILE_MERAM set to 'm'. 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.

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:

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:
