* OMAP: DSS2: DSI: change DSI bus_lock to semaphoreTomi Valkeinen2010-02-24
| | | | | | | | | | | | Physical DSI bus is protected by a mutex. This patch changed the mutex to a semaphore, so that we can lock and unlock the bus_lock from different threads. This is needed as the update process is started by user space program, and thus the lock is acquired in that context, but the lock can be released in different context, a work thread via irq.

* OMAP: DSS2: remove sub-panel systemTomi Valkeinen2010-02-18
| | | | | | | | | | | | The system to allow panel drivers to exists as attached to ctrl drivers did never work very well. It is not useed, and this patch removes it to make the driver cleaner. For now, controller drivers need to include also the panel driver code. In the future a proper mechanism for this should be developed, perhaps by creating busses for controllers.

* OMAP: DSS2: Check ctx loss count only when starting the first clockTomi Valkeinen2010-02-15
| | | | | | | | | | | | When OMAP PM layer is no-op/debug, the PM layer will increment context loss count with every call. This resulted DSS2 to restore context whenever a clock was enabled. This commit checks the context loss count only when the context actually could have been lost, ie. when enabling a clock when no clocks had been previously enabled.

* OMAP: DSS2: DSI: configure all DSI VCsTomi Valkeinen2010-02-15
| | | | | | | | | | | | | | Instead of configuring only VC0 to be usable, configure all four VCs similarly. This is needed to utilize the other VCs. Setting the FIFO sizes evenly for all VCs, regardless of how many VCs are actually used, is not optimal. However, this affects only cases when larger amounts of data are written or read via L4, meaning that normal use cases are not affected. At some point this could be optimized better to suit different use cases. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

* OMAP: DSS2: improve DSS clk src selectionTomi Valkeinen2010-02-15
| | | | | | | | | | | | dss_select_clk_source() was rather confusing. Selecting the source with enums is much clearer. The clk source selection is also stored into memory, so that we know what is the selected source, even when clocks are off. This is important during setup, as we need to what clocks to turn on before the clocks are turned on. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

* OMAP: 3430SDP: remove vdvi regulatorTomi Valkeinen2010-02-12

* OMAP: DSS2: enable VDDS_DSI when using DPITomi Valkeinen2010-02-12
| | | | | | | | | | | | | | | | | | | It looks like on OMAP3 some DSS pins need VDDS_DSI to function properly. This has not been confirmed from TI, but looking at figure 15-1 "Display subsystem highlight" from the TRM, some data pins come near the DSI and SDI blocks. This is not very hard evidence, but the fact remains that with the power on, pixels are ok, and with the power off, pixels are not ok. It may also be that VDDS_SDI is needed to power some pins, but as normally both VDDS_SDI and VDDS_DSI come from the same power source, this hasn't been shown. It seems that a single driver can only get a regulator once. This patch solves it by getting all the required regulators in one place, and from which the submodules then get the regulators they need.

* omapfb: lcd_ams_delta: add support for contrast controlJanusz Krzysztofik2010-02-12
| | | | | | | | | | | | | The patch extends the Amstrad Delta LCD panel driver with optional support for changing contrast using standard LCD class device API instead of setting it silently to a default value at panel enable. It also allows for lowering power consumption by turning off OMAP_PWL_CLK_ENABLE via lcd_ops.set_power callback.

* omapfb: Fix 12-bit display (RGB444 color mode) handlingJanusz Krzysztofik2010-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for RGB444 (12-bit) pixel format has been introduced into omapfb/lcdc by Mark Underwood on 2006-05-26 (commit f74edb6668aad9fc8e81585861b18f996c78a574) in preparation for Amstrad Delta (E3) videophone LCD display support. Before the Amstrad Delta LCD patch by Jonathan McDowell was applied (on 2006-08-04, commit 8d22fb2ea004cdb6379b54c1a8fd1546cfe40ed7), omapfb and lcdc code was changed substantially (commit e563dc81aa01bd8bbb01bc53975a15c398715f62 dated 2006-06-26) in a way that broke Mark's 12-bit display support. Than, a patch by Jonathan, that supposed to correct the problem, was introduced immediatelly (on 2006-08-04, commit e10a75b49e7a57ae17c28b705153c70eba15a8ef). As a result, the Amstrad Delta display was working correctly at boot time, with fbset reporting: geometry 480 320 480 320 16 ... rgba 4/8,4/4,4/0,0/0 However, after first framebuffer reinitialization, colors were no longer being displayed correctly and fbset was reporting: rgba 5/11,6/5,5/0,0/0 The patch tries to correct the issue by setting plane->color_mode depending on panel->bpp, not var->bits_per_pixel.

However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43 ("dock: make dock driver not a module") removed the possibility of having CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when CONFIG_ATA_ACPI=y. This makes the kernel ~5 Kb smaller for people who don't have a dock by allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y. Signed-off-by: Carlos R.
