drm/tilcdc: panel: Add support for enable GPIO

2014-09-17T00:55:27Z

In order to support the "enable GPIO" available in many panel devices, this commit adds a proper devicetree binding. By providing an enable GPIO in the devicetree, the driver can now turn off and on the panel device, and/or the backlight device. Both the backlight and the GPIO are optional properties.

drm/tilcdc: panel: Set return value explicitly

2014-09-17T00:55:19Z

Instead of setting an initial value for the return code, set it explicitly on each error path. This is just a cosmetic cleanup, as preparation for the enable GPIO support. Tested-by: Darren Etheridge Tested-by: Johannes Pointner Signed-off-by: Ezequiel Garcia Signed-off-by: Dave Airlie

drm/tilcdc: panel: Fix backlight devicetree support

2014-09-17T00:55:10Z

The current backlight support is broken; the driver expects a backlight-class in the panel devicetree node. Fix this by implementing it properly, getting an optional backlight from a phandle. This shouldn't cause any backward-compatibility DT issue because the current implementation doesn't work and is not even documented.

drm/tilcdc: panel: Use devm_kzalloc to simplify the error path

2014-09-17T00:55:05Z

Using the managed variant to allocate the resource makes the code simpler and less error-prone. Tested-by: Darren Etheridge Tested-by: Johannes Pointner Signed-off-by: Ezequiel Garcia Signed-off-by: Dave Airlie

drm/tilcdc: panel: Add missing of_node_put

2014-09-17T00:54:47Z

This commit adds the missing calls to of_node_put to release the node that's currently held by the of_get_child_by_name() call in the panel info parsing code. Tested-by: Darren Etheridge Tested-by: Johannes Pointner Signed-off-by: Ezequiel Garcia Signed-off-by: Dave Airlie

drm/tilcdc: Fix the error path in tilcdc_load()

2014-09-17T00:54:33Z

The current error path calls tilcdc_unload() in case of an error to release the resources. However, this is wrong because not all resources have been allocated by the time an error occurs in tilcdc_load(). To fix it, this commit adds proper labels to bail out at the different stages in the load function, and release only the resources actually allocated.

drm: add driver->set_busid() callback

2014-09-10T07:43:04Z

One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

drm/tilcdc: Fix build breakage

2014-07-10T02:01:38Z

Commit 34ea3d386347 ("drm: add register and unregister functions for connectors") probably missed out converting the drm_sysfs_connector_remove instances in the following files. Without this patch we get the following compilation error: ERROR: "drm_sysfs_connector_remove" [drivers/gpu/drm/tilcdc/tilcdc.ko] undefined!
