2018-03-01drm: omapdrm: dispc: Pass DISPC pointer to remaining dispc API functionsLaurent Pinchart1-2/+2
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).

2018-03-01drm: omapdrm: dispc: Pass DISPC pointer to dispc_ops operationsLaurent Pinchart1-2/+5
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 Pinchart1-13/+7
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: Store the debugfs root directory in struct dss_deviceLaurent Pinchart1-1/+2
As part of an effort to remove the usage of global variables in the driver, store the debugfs root directory in the dss_device structure instead of a global variable. 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/+6
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.

2018-03-01drm: omapdrm: dss: Pass DSS private structure to runtime PM functionsLaurent Pinchart1-1/+2
To prepare for the removal of the global variable storing DSS private data, pass its pointer to the dss_runtime_{get,put}() functions. As this requires getting hold of the dss_device structure in the callers, we add a new dss_get_device() function to retrieve it. The function currently returns a pointer to the global data structure, and will later be updated to get the pointer from device driver data when the DSS private structure will be allocated dynamically.

2018-03-01drm: omapdrm: Use unsigned int typeLaurent Pinchart1-1/+1

2017-12-19drm: omapdrm: Remove filename from header and fix copyright tagAndrew F. Davis1-1/+1

2017-08-16drm: omapdrm: hdmi: Configure the PHY from the HDMI core versionLaurent Pinchart1-1/+1
The OMAP4 and OMAP5 HDMI PHYs have different properties that require specific handling in the HDMI PHY driver. This needs knowledge of the PHY version, which is currently inferred from the DSS version. As part of the effort to remove usage of the DSS version, use the HDMI controller version instead.

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.

2016-06-07drm/omapdrm: Add gamma table support to DSS dispcJyri Sarha1-3/+0
Add gamma table support to DSS dispc. DSS driver initializes the default gamma table at component bind time and holds a copy of all gamma tables in its internal data structure. Each call to dispc_mgr_set_gamma() updates the internal table and triggers write to the HW, if it is enabled. The tables are restored to HW in PM resume callback. The drivers internal data structure match the HW tables in size and in number of significant bits per color component. The dispc_mgr_set_gamma() converts the size of any given table for the internal data structure using linear interpolation. Default gamma table is restored if NULL is given in place of gamma lut. dispc_mgr_gamma_size() gives HW gamma table size for the channel and returns 0 if gamma table is not supported by the HW or the DSS driver.

2016-03-03drm/omap: HDMI: change enable/disable to avoid sync-lostsTomi Valkeinen1-8/+8
We occasionally see DISPC sync-lost errors when enabling and disabling HDMI. Sometimes we get only a few, which get handled (ignored) by the driver, but sometimes there's a flood of the errors which doesn't seem to stop. The HW team has root caused this to the order in which HDMI and DISPC are enabled/disabled. Currently we enable HDMI first, and then DISPC, and vice versa when disabling. HW team's suggestion is to do it the other way around. This patch changes the order, but this has two side effects as the pixel clock is produced by HDMI, and the clock is not running when we enable/disable DISPC: * When enabling DISPC first, we don't get vertical sync events * When disabling DISPC last, we don't get FRAMEDONE event At the moment we use both of those to verify that DISPC has been enabled/disabled properly. Thus this patch also needs to change the omapdrm and omapdss which handle the DISPC side. Signed-off-by: Tomi Valkeinen <[email protected]> Acked-by: Laurent Pinchart <[email protected]>
