drm/omap: fix compile error when DPI is disabled

2018-03-14T08:39:50Z

When CONFIG_OMAP2_DSS_DPI is disabled, compilation fails due to: drivers/gpu/drm/omapdrm/dss/dss.h:388:25: error: conflicting types for ‘port’ struct device_node *port, ^~~~ Fix this by renaming the first parameter correctly. Signed-off-by: Tomi Valkeinen

drm/omap: add writeback funcs to dispc_ops

2018-03-01T07:18:18Z

Add writeback specific dispc functions to dispc_ops so that omapdrm can use them. Also move 'enum dss_writeback_channel' to the public omapdss.h for omapdrm. Signed-off-by: Tomi Valkeinen

drm/omap: set WB channel-in in wb_setup()

2018-03-01T07:18:18Z

We need to know the WB channel-in in wb_setup() to be able to configure WB properly for capture mode. At the moment channel-in is set separately. This patch moves channel-in to wb_setup(). Signed-off-by: Tomi Valkeinen

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: Support passing private data to debugfs show handlers

2018-03-01T07:18:18Z

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.
