2018-09-03drm/omap: dss: Move common device operations to common structureLaurent Pinchart1-2/+2
The various types of omapdss_*_ops structures define multiple operations that are not specific to a bus type. To simplify the code and remove dependencies on specific bus types move those operations to a common structure. Operations that are specific to a bus type are kept in the specialized ops structures.

2018-03-01drm: omapdrm: venc: Allocate the venc private data structure dynamicallyLaurent Pinchart1-204/+238
The venc private data structure is currently stored as a global variable. While no platform with multiple VENC encoders currently exists nor is planned, this doesn't comply with the kernel device model and should thus be fixed.

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.

2018-03-01drm: omapdrm: dss: Pass omap_dss_device pointer to dss_mgr_*() functionsLaurent Pinchart1-12/+6
The dss_mgr_*() functions take a channel argument to identify the channel they operate on. This prevents the functions from accessing driver data structures without resorting to global variables. In an effort to remove global variables, pass the omap_dss_device pointer associated with the channel instead. This will be used to look up the omap_drm_private data structure to pass to the dss_mgr_ops. Signed-off-by: Laurent Pinchart <[email protected]> Reviewed-by: Sebastian Reichel <[email protected]>

2018-03-01drm: omapdrm: dss: Support passing private data to debugfs show handlersLaurent Pinchart1-3/+8
To simplify implementation of debugfs seq_file show handlers, the driver passes the pointer to the show function through the debugfs_create_file data pointer. This prevents using the pointer to pass driver private data to the show handler, and requires all handlers to use global variables to access private data. To prepare for the removal of global private data in the driver, rework the debugfs infrastructure to allow passing a private data pointer to show handlers. The price to pay is explicit removal of debugfs files to free the internally allocated memory. This is desirable anyway as debugfs entries should be removed when a component driver is unbound, otherwise crashes will occur due to access to freed memory when the components will be dynamically allocated instead of stored in global variables.

2017-12-19drm: omapdrm: Remove filename from header and fix copyright tagAndrew F. Davis1-2/+0

2017-08-23drm/omap: fix analog tv-out modecheckTomi Valkeinen1-14/+51
omapdrm rejects all venc (analog tv-out) videomodes, due to somewhat strict checking of the values, making tv-out unusable. We only support two videomodes, one for PAL and one for NTSC, so instead of trying to check every field in the videomode struct, this patch makes the driver check only the pixel clock and the size of the display.

2017-04-06drm: omap: use common OF graph helpersRob Herring1-1/+2
The OMAP driver has its own OF graph helpers that are similar to the common helpers. This commit replaces most of the calls with the common helpers. There's still a couple of custom helpers left, but the driver needs more extensive changes to get rid of them. In dss_init_ports, we invert the loop, looping through the known ports and matching them to DT nodes rather than looping thru DT nodes and matching them to the ports.
