OMAPDSS: HDMI4: fix error handling

2015-06-17T12:44:29+00:00

Error handling in hdmi_power_on_full() is not correct, and could leave resources unfreed. Fix this by arranging the error labels correctly. Signed-off-by: Tomi Valkeinen

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.

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

OMAPDSS: HDMI: use common DSS PLL support

2014-11-12T11:40:27+00:00

Now that we have the common DSS PLL support, change HDMI to use it. This results in quite a lot of changes, but almost all of them are trivial name changes. The function to program the PLL settings can be removed from hdmi_pll.c, as the common PLL API contains the same functionality. Signed-off-by: Tomi Valkeinen
