Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts."

Current SuperH (like sh73a0) can control all of these clocks by CPG (Clock Pulse Generator). It means we can control it by clock framework only. But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS, and only sh7372 has PHYCTRL::PLLDS. But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was overwrote since the callback timing of clock setting was changed by c2658b70f06108361aa5024798f9c1bf47c73374 (fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()). To solve this issue, this patch adds extra .phyctrl. This patch adds detail explanation for unclear mipi settings and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meram_register(), meram_unregister() and meram_update() operations check that the pointers they get from the caller are not NULL.

The range of reserved ICBs (for instance to be used through UIO), if any, is passed in the platform data reserved_icbs field as a bitmask.

* | | OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen2012-01-261-0/+5
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board if the HDMI PHY is kept powered on when the cable is not connected. This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

The overlay info is set with ovl->set_overlay_info(), and made into use with mgr->apply(). This doesn't work properly, as the enable/disable status may affect also other overlays, for example when using fifo-merge. Thus the enabling and disabling of the overlay needs to be done outside the normal overlay configuration. This patch achieves that by doing the following things: 1) Add function pointers to struct omap_overlay: enable(), disable() and is_enabled(). These are used to do the obvious. The functions may block. 2) Move the "enabled" field from struct omap_overlay to ovl_priv_data. 3) Add a new route for settings to be applied to the HW, called "extra_info". The status of the normal info and extra_info are tracked separately. The point here is to allow the normal info to be changed and applied in non-blocking matter, whereas the extra_info can only be changed when holding the mutex. This makes it possible to, for example, set the overlay enable flag, apply it, and wait until the HW has taken the flag into use. This is not possible if the enable flag would be in the normal info, as a new value for the flag could be set at any time from the users of omapdss.

| * | OMAPDSS: DSI: call mgr_enable/disable for cmd mode displaysTomi Valkeinen2011-12-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code uses dsi_video_mode_enable/disable functions to enable/disable DISPC output for video mode displays. For command mode displays we have no notion in the DISPC side of whether the panel is enabled, except when a dss_mgr_start_update() call is made. However, to properly maintain the DISPC state in apply.c, we need to know if a manager used for a manual update display is currently in use. This patch achieves that by changing dsi_video_mode_enable/disable to dsi_enable/disable_video_output, which is called by both video and command mode displays. For video mode displays it starts the actual pixel stream, as it did before. For command mode displays it doesn't do anything else than mark that the manager is currently in use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current way of handling overlay-manager links is a bit strange: each manager has a static array, containing pointers to all the overlays (even those used by other managers).

| * | OMAPDSS: hide manager's enable/disable()Tomi Valkeinen2011-12-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | omap_overlay_manager struct contains enable() and disable() functions. However, these are only meant to be used from inside omapdss, and thus it's bad to expose the functions. This patch adds dss_mgr_enable() and dss_mgr_disable() functions to apply.c, which handle enabling and disabling the output. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | OMAPDSS: remove partial update from DSITomi Valkeinen2011-12-021-6/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Partial update for manual update displays has never worked quite well: * The HW has limitations on the update area, and the x and width need to be even. * Showing a part of a scaled overlay causes artifacts. * Makes the management of dispc very complex Considering the above points and the fact that partial update is not used anywhere, this and the following patches remove the partial update support. This will greatly simplify the following re-write of the apply mechanism to get proper locking and additional features like fifo-merge. This patch removes the partial update from the dsi.c.

| * ARM: OMAP: HWMOD: Unify DSS resets for OMAPsTomi Valkeinen2011-11-081-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a custom DSS reset function used on OMAPs from OMAP2 forward. The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the other DSS modules also, thus breaking the HWMOD model where every DSS module is handled independently. This fixes the problem with DSS reset on OMAP4, caused by the fact that because there's no SW reset for dss_core on OMAP4, the HWMOD framework doesn't try to reset dss_core and thus the DSS clocks were never enabled at the same time. This causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi. The common reset function will also allow us to fix another problem in the future: before doing a reset we need to disable DSS outputs, which are in some cases enabled by the bootloader, as otherwise DSS HW seems to get more or less stuck, requiring a power reset to recover.
