OMAPDSS: componentize omapdss

2015-06-17T10:44:53+00:00

omapdss kernel module contains drivers for multiple devices, one for each DSS submodule. The probing we have at the moment is a mess, and doesn't give us proper deferred probing nor ensure that all the devices are probed before omapfb/omapdrm start using omapdss. This patch solves the mess by using the component system for DSS submodules. The changes to all DSS submodules (dispc, dpi, dsi, hdmi4/5, rfbi, sdi, venc) are the same: probe & remove functions are changed to bind & unbind, and new probe & remove functions are added which call component_add/del. The dss_core driver (dss.c) acts as a component master. Adding and matching the components is simple: all dss device's child devices are added as components. However, we do have some dependencies between the drivers. The order in which they should be probed is reflected by the list in core.c (dss_output_drv_reg_funcs). The drivers are registered in that order, which causes the components to be added in that order, which makes the components to be bound in that order. This feels a bit fragile, and we probably should improve the code to manage binds in random order. However, for now, this works fine. Signed-off-by: Tomi Valkeinen Acked-by: Laurent Pinchart

OMAPDSS: remove uses of init/exit

2015-06-17T10:44:47+00:00

The following patches will add component handling to omapdss, improving the handling of deferred probing. However, at the moment we're using quite a lot of __inits and __exits in the driver, which prevent normal dynamic probing and removal. This patch removes most of the uses of __init and __exit, so that we can register drivers after module init, and so that we can unregister drivers even if the module is built-in.

Merge branch 'platform/remove_owner' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux into driver-core-next

Remove all .owner fields from platform drivers

OMAPDSS: set suppress_bind_attrs

2014-10-22T08:07:07+00:00

omapdss drivers cannot handle devices being unbound while the devices are part of a connected display pipeline. Module refcounts are used to prevent unloading the modules, but one can still manually unbind the devices via sysfs, causing crash. Set suppress_bind_attrs to disable the bind/unbind support via sysfs. Signed-off-by: Tomi Valkeinen

video: fbdev: omap2: dss: drop owner assignment from platform_drivers

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

video: move fbdev to drivers/video/fbdev

2014-04-17T05:10:19+00:00

The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
