| * | OMAPDSS: DISPC: rename dispc_mgr_enable/disable to _syncTomi Valkeinen2012-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current dispc_mgr_enable/disable function are blocking, and do a bit too much for omapdrm. We'll expose new enable & disable functions that will just set the bits in the registers in the following patches. This patch renames the current functions to *_sync, to make it clear that they are blocking, and also to free up the dispc_mgr_enable/disable names for these new functions.

| * | OMAPDSS: DISPC: use dss_feat_get_num_ovls()Tomi Valkeinen2012-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | Use dss_feat_get_num_ovls() in dispc.c instead of omap_dss_get_num_overlays() to remove the dependency to overlay.c. Note that we still have uses of omap_dss_get_num_overlays() in dispc.c, but these will be moved out in the future patches. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | OMAPDSS: remove initial display code from omapdssTomi Valkeinen2012-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently omapdss driver sets up the initial connections between overlays, overlay manager and a panel, based on default display parameter coming from the board file or via module parameters. This is unnecessary, as it's the higher level component that should decide what display to use and how. This patch removes the code from omapdss, and implements similar code to omapfb. The def_disp module parameter and the default display platform_data parameter are kept in omapdss, but omapdss doesn't do anything with them. It will just return the default display name with dss_get_default_display_name() call, which omapfb uses. This is done to keep the backward compatibility.

| * | OMAPDSS: get the dss version from core pdevTomi Valkeinen2012-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The output drivers get the omapdss hw version from the platform data for their respective output device. This doesn't work with DT, as there's no platform data for them. Add a new function, omapdss_get_version(), which returns the dss version from the core device, which will have platform data on DT also. The function is exported so that users of omapdss can also use it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | OMAPDSS: remove omap_dss_device's suspend/resumeTomi Valkeinen2012-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The panel drivers contain enable, disable, suspend and resume calls. The suspend and resume are effectively identical to disable and enable. This patch removes panel suspend and enable code from omapdss and the panel drivers, and replaces their use with enable and disable. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* | OMAPDSS: DISPC: cleanup lcd/digit enable/disableTomi Valkeinen2012-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently have a single function to enable and disable the manager output for LCD and DIGIT. The functions are a bit complex, as handling both enable and disable require some extra steps to ensure that the output is enabled or disabled properly without errors before exiting the function. The code can be made simpler to understand by splitting the functions into separate enable and disable functions. We'll also clean up the comments and some parameter names at the same time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dispc has a bunch of functions used to configure output related parameters: - dispc_mgr_set_io_pad_mode - dispc_mgr_enable_stallmode - dispc_mgr_enable_fifohandcheck - dispc_mgr_set_clock_div - dispc_mgr_set_tft_data_lines - dispc_lcd_enable_signal_polarity - dispc_mgr_set_lcd_type_tft These are all called together, and the configuration values are taken from struct dss_lcd_mgr_config. Instead of exposing those individual dispc functions, create a new one, dispc_mgr_set_lcd_config(), which is used to configure the above parameters from values in struct dss_lcd_mgr_config.

| | | | | | | | | | | | | | | | | | | | When we enable an output we don't check if we need to register the vsync isr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If dsi_get_dsidev_from_id() is called with a DSI module id that does not exist on the board, the function will crash as omap_dss_get_output() will return NULL. This happens on omap3 boards when dumping DSI clocks, as the dumping code will try to get the dsidev for DSI modules 0 and 1, but omap3 only has DSI module 0. Also clean up the id -> output mapping, so that if the function is called with invalid module ID it will return NULL.

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The various functions in dispc and dsi such as print_irq_status(), print_irq_status_vc(), print_irq_status_cio() and _dsi_print_reset_status() consist of a number of debug prints which need to be enabled all at once or none at all. So, these debug prints in corresponding functions are replaced with one dynamic debug enabled pr_debug() each.

The use of dynamic debugging provides more flexibility as each debug statement can be enabled or disabled dynamically on basis of source filename, line number, module name etc., by writing to a control file in debugfs filesystem. For better understanding please refer to Documentation/dynamic-debug-howto.txt. The DSSDBGF() differs from DSSDBG() by providing function name. However, function name, line number, module name and thread ID can be printed through dynamic debug by setting appropriate flags 'f','l','m' and 't' in the debugfs control file. So, DSSDBGF instances are replaced with DSSDBG.

CONFIG_OMAP2_DSS_DEBUG enables DEBUG flag and CONFIG_OMAP2_DSS_DEBUGFS enables creation of debugfs for OMAPDSS. Both the config options are disabled by default and can be enabled independently of one another as per convenience.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In OMAPDSS the DEBUG flag is set only after the OMAPDSS module is called, for which the debugging capabilities are available only after its proper initialization. As a result of which tracking of bugs prior to or during initial process becomes difficult. So, the definition of DEBUG is being moved to the corresponding Makefile.

* | | OMAPDSS: DISPC: Configure color conversion coefficients for writebackArchit Taneja2012-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writeback pipeline receives RGB data from one of the overlays or one of the overlay managers. If the target color mode is YUV422 or NV12, we need to convert the RGB pixels to YUV. The scaler in WB then converts it to the target color mode. Hence, the color conversion coefficients that need to be programmed are the ones which convert a RGB24 pixel to YUV444. Program these coefficients for writeback pipeline. Rearrange the code a bit to configure different coefficients for overlays and writeback. Signed-off-by: Archit Taneja <archit@ti.com>

The most optimal configuration for writeback is to push out data to the interconnect the moment writeback pushes enough pixels in the FIFO to form a burst. This reduces the chance of writeback overflowing it's FIFO. Signed-off-by: Archit Taneja <archit@ti.com>
