2010-02-24OMAP: DSS2: DSI: remove auto-update perf measurementTomi Valkeinen
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>
2010-02-24OMAP: DSS2: DSI: change DSI bus_lock to semaphoreTomi Valkeinen
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.

2010-02-23OMAP: DSS2: fix get_dsi/dispc_clk_source() usageTomi Valkeinen

2010-02-18OMAP: DSS2: fix driver probe error handlingTomi Valkeinen
If driver's probe failed, the uninit was not called. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-02-18OMAP: DSS2: remove sub-panel systemTomi Valkeinen
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.

2010-02-15OMAP: DSS2: Check ctx loss count only when starting the first clockTomi Valkeinen
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.

2010-02-15OMAP: DSS2: DSI: remove dsi_vc_print_status()Tomi Valkeinen
It was not used. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-02-15OMAP: DSS2: DSI: configure all DSI VCsTomi Valkeinen
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>
2010-02-15OMAP: DSS2: DSI: export dsi_vc_enable_hs()Tomi Valkeinen

Helper function to clean up the checking of the bus lock. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-02-15OMAP: DSS2: improve DSS clk src selectionTomi Valkeinen
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>
2010-02-15OMAP: DSS2: fix irq-stats compilationTomi Valkeinen
Fix compilation of the CONFIG_OMAP2_DSS_COLLECT_IRQ_STATS feature. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-02-12OMAP: DSS2: enable VDDS_DSI when using DPITomi Valkeinen
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.
