* OMAP: DSS2: DSI: remove auto-update perf measurementTomi Valkeinen2010-02-24
| | | | | | | | | | | Remove performance measurement for auto-update. Auto-update and thus performance measurement cannot be supported after the driver change where the control is moved to display drivers. This is part of a larger patch-set, which moves the control from omapdss driver to the display driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
* 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: fix get_dsi/dispc_clk_source() usageTomi Valkeinen2010-02-23

* OMAP: DSS2: OMAPFB: fix cleanup on dssdev enable errorTomi Valkeinen2010-02-18
| | | | | | If enabling a dss device failed, omapfb didn't exit, leading to crash. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
* OMAP: DSS2: OMAPFB: fix dssdev cleanup on errorTomi Valkeinen2010-02-18
| | | | | | | If there was a dss device without a driver and thus omapfb probe failed, ref counts could be left to dss devices. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
* OMAP: DSS2: fix driver probe error handlingTomi Valkeinen2010-02-18

* 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: DSI: export dsi_vc_enable_hs()Tomi Valkeinen2010-02-15

* 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: DSS2: OMAPFB: implement OMAPFB_GET_DISPLAY_INFOTomi Valkeinen2010-02-15
| | | | | | | | Previously the only place to get the size of the display was from the DSS's sysfs interface, making, for example, configuring overlays and doing updates on manual displays more difficult. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

* OMAP: 3430SDP: remove vdvi regulatorTomi Valkeinen2010-02-12
| | | | | | | The regulator is now enabled by DSS driver, and thus the panel driver doesn't need to touch it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
* 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.

* OMAP: DSS2: OMAPFB: fix crash when panel driver was not loadedTomi Valkeinen2010-01-12
| | | | | | | | | | If the panel's probe had failed, omapfb would still go on, eventually crashing. A better fix would be to handle each display properly, and leaving just the failed display out. But that is a bigger change. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
