drm/bridge: dw-hdmi: Adapt to bridge API change

2015-01-28T09:01:30Z

Commit fbc4572e9c48e45b ("drm/bridge: make bridge registration independent of drm flow") introduced some drm/bridge API modifications. Make the necessary changes so that we can avoid the build breakage: drivers/gpu/drm/bridge/dw_hdmi.c: In function 'dw_hdmi_bridge_destroy': drivers/gpu/drm/bridge/dw_hdmi.c:1378:2: error: implicit declaration of function 'drm_bridge_cleanup' [-Werror=implicit-function-declaration] drivers/gpu/drm/bridge/dw_hdmi.c: At top level: drivers/gpu/drm/bridge/dw_hdmi.c:1471:2: error: unknown field 'destroy' specified in initializer drivers/gpu/drm/bridge/dw_hdmi.c: In function 'dw_hdmi_register': drivers/gpu/drm/bridge/dw_hdmi.c:1535:2: error: implicit declaration of function 'drm_bridge_init' [-Werror=implicit-function-declaration] Signed-off-by: Fabio Estevam Signed-off-by: Thierry Reding

drm/bridge: dw-hdmi: Fix return error path

2015-01-28T09:01:21Z

If devm_request_threaded_irq() fails we should jump to 'err_iahb' label that will disable the clocks that were previously enabled. Signed-off-by: Fabio Estevam Acked-by: Philipp Zabel Signed-off-by: Thierry Reding

drm/bridge: ptn3460: probe connector at the end of bridge attach

2015-01-28T07:47:29Z

Force bridge connector detection at the end of the bridge attach. This is needed to detect the bridge connector early.

drm/bridge: make bridge registration independent of drm flow

2015-01-28T07:45:40Z

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.

drm/bridge: do not pass drm_bridge_funcs to drm_bridge_init

2015-01-28T07:45:40Z

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.

drm/bridge: ptn3460: Few trivial cleanups

2015-01-28T07:45:39Z

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.
