2014-07-10drm/tilcdc: Fix build breakageSachin Kamat
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!

2014-07-08drm/tilcdc: remove submodule destroy callsGuido Martínez
The TI tilcdc driver is designed with a notion of submodules. Currently, at unload time, these submodules are iterated and destroyed. Now that the tilcdc remove order is fixed, this can be handled perfectly by the kernel using the device infrastructure, since each submodule is a kernel driver itself, and they are only destroy()'ed at unload time. Therefore we move the destroy() functionality to each submodule's remove(). Also, remove some checks in the unloading process since the new code guarantees the resources are allocated and need a release.

2014-07-08drm/tilcdc: tfp410: fix dangling sysfs connector nodeGuido Martínez
Add a drm_sysfs_connector_remove call when we destroy the panel to make sure the connector node in sysfs gets deleted. This is required for proper unload and re-load of this driver, otherwise we will get a warning about a duplicate filename in sysfs.

2014-06-19drm: add register and unregister functions for connectorsThomas Wood
Introduce generic functions to register and unregister connectors. This provides a common place to add and remove associated user space interfaces.

2013-08-23i2c: move OF helpers into the coreWolfram Sang
I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-06-20gpu:drm:tilcdc: get preferred_bpp value from DTBenoit Parrot
The preferred_bpp value in currently hard-coded to 16. This causes color corruption on the am335x-evm lcd panel which requires 32 bpp instead. This changes attempts to use the configured bpp value from the DT or built-in panel-info struct.

2013-04-26drm/tilcdc: use only a single module device tableArnd Bergmann
The tilcdc driver fails to be built as a module because of extraneous MODULE_DEVICE_TABLE entries: drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here Since the entire point of these entries is to make the module autoload when one of the devices is present, it's enough to keep the one entry for "ti,am33xx-tilcdc", which should always be there if any of the others are.

2013-02-19drm/tilcdc: add TI LCD Controller DRM driver (v4)Rob Clark
A simple DRM/KMS driver for the TI LCD Controller found in various smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the CMA helpers. Currently only the TFP410 DVI encoder is supported (tested with beaglebone + DVI cape). There are also various LCD displays, for which support can be added (as I get hw to test on), and an external i2c HDMI encoder found on some boards. The display controller supports a single CRTC. And the encoder+ connector are split out into sub-devices. Depending on which LCD or external encoder is actually present, the appropriate output module(s) will be loaded. v1: original v2: fix fb refcnting and few other cleanups v3: get +/- vsync/hsync from timings rather than panel-info, add option DT max-bandwidth field so driver doesn't attempt to pick a display mode with too high memory bandwidth, and other small cleanups v4: remove some unneeded stuff from panel-info struct, properly set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: Koen Kooi <koen@dominion.thruhere.net>
