2018-09-03drm/omap: dss: Move common device operations to common structureLaurent Pinchart
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: dss: Pass omap_dss_device pointer to dss_mgr_*() functionsLaurent Pinchart
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.

2018-03-01drm: omapdrm: dss: Support passing private data to debugfs show handlersLaurent Pinchart
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.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

This mechanically converts all remaining cases of ancient open-coded timer setup with the old setup_timer() API, which is the first step in timer conversions. This has no behavioral changes, since it ultimately just changes the order of assignment to fields of struct timer_list when finding variations of: init_timer(&t); f.function = timer_callback; t.data = timer_callback_arg; to be converted into: setup_timer(&t, timer_callback, timer_callback_arg); The conversion is done with the following Coccinelle script, which is an improved version of scripts/cocci/api/setup_timer.cocci, in the following ways: - assignments-before-init_timer() cases - limit the .data case removal to the specific struct timer_list instance - handling calls by dereference (timer->field vs timer.field) spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/setup_timer.cocci @fix_address_of@ expression e; @@ init_timer( -&(e) +&e , ...) // Match the common cases first to avoid Coccinelle parsing loops with // "... when" clauses. @match_immediate_function_data_after_init_timer@ expression e, func, da; @@ -init_timer +setup_timer ( \(&e\|e\) +, func, da ); ( -\(e.function\|e->function\) = func; -\(e.data\|e->data\) = da; | -\(e.data\|e->data\) = da; -\(e.function\|e->function\) = func; ) @match_immediate_function_data_before_init_timer@ expression e, func, da; @@ ( -\(e.function\|e->function\) = func; -\(e.data\|e->data\) = da; | -\(e.data\|e->data\) = da; -\(e.function\|e->function\) = func; ) -init_timer +setup_timer ( \(&e\|e\) +, func, da ); @match_function_and_data_after_init_timer@ expression e, e2, e3, e4, e5, func, da; @@ -init_timer +setup_timer ( \(&e\|e\) +, func, da ); ... when != func = e2 when != da = e3 ( -e.function = func; ... when != da = e4 -e.data = da; | -e->function = func; ... when != da = e4 -e->data = da; | -e.data = da; ... when != func = e5 -e.function = func; | -e->data = da; ... when != func = e5 -e->function = func; ) @match_function_and_data_before_init_timer@ expression e, e2, e3, e4, e5, func, da; @@ ( -e.function = func; ... when != da = e4 -e.data = da; | -e->function = func; ... when != da = e4 -e->data = da; | -e.data = da; ... when != func = e5 -e.function = func; | -e->data = da; ... when != func = e5 -e->function = func; ) ... when != func = e2 when != da = e3 -init_timer +setup_timer ( \(&e\|e\) +, func, da ); @r1 exists@ expression t; identifier f; position p; @@ f(...) { ... when any init_timer@p(\(&t\|t\)) ... when any } @r2 exists@ expression r1.t; identifier g != r1.f; expression e8; @@ g(...) { ... when any \(t.data\|t->data\) = e8 ... when any } // It is dangerous to use setup_timer if data field is initialized // in another function. @script:python depends on r2@ p << r1.p; @@ cocci.include_match(False) @r3@ expression r1.t, func, e7; position r1.p; @@ ( -init_timer@p(&t); +setup_timer(&t, func, 0UL); ... when != func = e7 -t.function = func; | -t.function = func; ... when != func = e7 -init_timer@p(&t); +setup_timer(&t, func, 0UL); | -init_timer@p(t); +setup_timer(t, func, 0UL); ... when != func = e7 -t->function = func; | -t->function = func; ... when != func = e7 -init_timer@p(t); +setup_timer(t, func, 0UL); ) Signed-off-by: Kees Cook <keescook@chromium.org>

2017-08-15drm: omapdrm: dsi: Store DSI model and PLL hardware data in OF dataLaurent Pinchart
The DSI PLL hardware data and DSS channels are selected based on the OMAP SoC model. There's no need for fine-grained model information, as the driver only needs to differentiate between OMAP3, OMAP4 and OMAP5. As this can be done through the DSI compatible string, store the corresponding information in OF match data instead to avoid accessing the OMAP SoC model.

The devm_ioremap_resource() call can handle being given a NULL resource, and prints an error message when mapping fails.

2017-04-06drm: omap: use common OF graph helpersRob Herring
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.

2017-04-03drm/omap: display: don't use dsi_get_pixel_size()Tomi Valkeinen
display.c uses dsi_get_pixel_size() which is implemented in the DSI driver, and we won't have that in the omapdss-base module, to which we want to move display.c This patch changes display.c not to use dsi_get_pixel_size(). The call can be replaced with a simple check for OMAP_DSS_DSI_FMT_RGB565. We can also make dsi_get_pixel_size() static as it's no longer used outside dsi.c.
