drm: omapdrm: dispc: Pass DISPC pointer to dispc_ops operations

2018-03-01T07:18:18Z

This removes the need to access the global DISPC private data in those functions (both for the current accesses and the future ones that will be introduced when allocating the DISPC private data dynamically). In order to allow the omapdrm side to call the dispc_ops with a DISPC pointer, we also introduce a new function dss_get_dispc() to retrieve the DISPC corresponding to the DSS.

drm: omapdrm: dss: Store dispc ops in dss_device structure

2018-03-01T07:18:18Z

Remove the global dispc ops variable by storing it in the dss_device structure. Signed-off-by: Laurent Pinchart Reviewed-by: Sebastian Reichel

drm: omapdrm: dss: Store DSS device pointer in the omapdrm private data

2018-03-01T07:18:18Z

The dss_device is the top-level component in the omapdss driver. Give the omapdrm driver access to the dss_device pointer in order to obtain pointers to all other components from it. This requires a new global variable in the omapdss driver that will be removed when merging the omapdrm and omapdss drivers, but will already allow removal of several other global variables. As this partly duplicates the omapdss_is_initialized() API, reimplement it as an inline function wrapping omapdss_get_dss(). Signed-off-by: Laurent Pinchart Reviewed-by: Sebastian Reichel

drm: omapdrm: Remove filename from header and fix copyright tag

2017-12-19T09:21:32Z

Having the filename in the header serves little purpose and is often wrong after renames as it is here in several places, just drop it from all omapdrm files. While we are here unify the copyright tags to the TI recommended style. Signed-off-by: Andrew F. Davis

drm/omap: dss: Support for detecting display stack readiness

2017-04-03T09:36:40Z

When omapdss is loaded (all core components are in place) create a list of devices used in the display graph. This list later can be used by omapdrm via the omapdss_stack_is_ready() function to check that these components are loaded. Based on this information, omapdrm can defer probe in case when the omapdss stack is not ready yet. Signed-off-by: Peter Ujfalusi Signed-off-by: Tomi Valkeinen

drm/omap: add dispc_ops

2017-04-03T09:36:40Z

We want to change the dispc API from plain functions to a struct with functions pointers, so that omapdrm can call either omapdss or omapdss6 depending on the platform. This patch adds 'struct dispc_ops' and adds functions to omapdss-base to set and get the ops. Signed-off-by: Tomi Valkeinen

drm/omap: move dss_initialized to omapdss-base

2017-04-03T09:36:40Z

omapdss_is_initialized() is used to find out if omapdss has been probed successfully. This patch moves the related code to the common omapdss-base module, so that the same support will be there for both omapdss and omapdss6. Signed-off-by: Tomi Valkeinen

drm/omap: add omapdss-base.ko

2017-04-03T09:36:40Z

We are working towards enabling omapdss6, which will consists of a new dss, dispc and dpi drivers. omapdss6 will be a new module. The panel, encoder and omapdrm will need to use either the current omapdss driver or the new omapdss6 driver, depending on the platform. This will be implemented with a common base module and function pointers. This patch adds a skeleton omapdss-base.ko module, to which we'll be moving common dss functionality like registration of the panels. Signed-off-by: Tomi Valkeinen
