2011-03-11OMAP: DSS2: Functions to request/release DSI VCsArchit Taneja
Introduce functions which request and release VC's. This will be used in panel drivers in their probes. omap_dsi_request_vc() takes in the pointer to the omap_dss_device, the VC_ID parameter which goes into the header of the DSI packets, and returns a Virtual channel number (or virtual channel register set) which it can use. omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel number and the VC_ID that needs to be set for the specifed Virtual Channel. omap_dsi_release_vc() takes the omap_dss_device pointer and the Virtual Channel number that needs to be made free. Initialisation of VC parameters is done in dsi_init(). Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-11OMAP: DSS2: Remove unneeded cpu_is_xxx checksTomi Valkeinen
cpu_is_omapxxx() was used previously to select the supported interfaces. Now that the interfaces are platform devices, we no longer need to do the check when registering the driver. Thus we can just remove the checks. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-11OMAP: DSS2: Move DPI & SDI init into DSS plat driverTomi Valkeinen
DPI and SDI are different from the other interfaces as they are not hwmods and there is not platform driver for them. They could be said to be a part of DSS or DISPC modules, although it's not a clear definition. This patch moves DPI and SDI initialization into DSS platform driver, making the code more consistent: omap_dss_probe() only initializes platform drivers now.

2011-03-11OMAP: DSS2: Remove FB_OMAP_BOOTLOADER_INIT supportTomi Valkeinen
FB_OMAP_BOOTLOADER_INIT does not work, and it was only partially implemented for SDI. This patch removes support for FB_OMAP_BOOTLOADER_INIT to clean up the code and to remove any assumptions that FB_OMAP_BOOTLOADER_INIT would work. Proper implementation is much more complex, requiring early boot time register and clock handling to keep the DSS running. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-11OMAP2PLUS: DSS2: DSI: Generalize DSI PLL Clock NamingArchit Taneja
DSI PLL output clock names have been made more generic. The clock name describes what the source of the clock and what clock is used for. Some of DSI PLL parameters like dividers and DSI PLL source have also been made more generic. dsi1_pll_fclk and dsi2_pll_fclk have been changed as dsi_pll_hsdiv_dispc_clk and dsi_pll_hsdiv_dsi_clk respectively. Also, the hsdividers are now named regm_dispc and regm_dsi instead of regm3 and regm4. Functions and macros named on the basis of these clock names have also been made generic.

2011-03-11OMAP2PLUS: DSS2: Use dss features to get clock source names of current OMAPArchit Taneja
Clock source names vary across OMAP2/3 and OMAP4, the clock source enum names have been made generic in the driver, but for purposes of debugging and dumping clock sources, it is better to preserve the actual TRM name of the clock. Introduce a dss feature function 'dss_feat_get_clk_source_name()' which returns a string with the TRM clock name for the current OMAP in use. The OMAP specific name is printed along the generic name within brackets. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-03-11OMAP: DSS2: Have separate irq handlers for DISPC and DSIarchit taneja
Currently, the core DSS platform device requests for an irq line for OMAP2 and OMAP3. Make DISPC and DSI platform devices request for a shared IRQ line. On OMAP3, the logical OR of DSI and DISPC interrupt lines goes to the MPU. There is a register DSS_IRQSTATUS which tells if the interrupt came from DISPC or DSI. On OMAP2, there is no DSI, only DISPC interrupts goto the MPU. There is no DSS_IRQSTATUS register. Hence, it makes more sense to have separate irq handlers corresponding to the DSS sub modules instead of having a common handler. Since on OMAP3 the logical OR of the lines goes to MPU, the irq line is shared among the IRQ handlers. The hwmod irq info has been removed for DSS to DISPC and DSI for OMAP2 and OMAP3 hwmod databases. The Probes of DISPC and DSI now request for irq handlers.

2011-03-11OMAPFB: Adding a check for timings in set_def_modeJanorkar, Mayuresh
When omapfb.mode is passed through bootargs, when omapfb is setting mode, it would check if timings passed are fine for panel attached to it. It makes use of check_timing API provided by the panel. In current code if check_timing API is not available for attached panel, OMAPFB would return -EINVAL and BPP sent via bootargs will not have any effect. In case of panels like TAAL panel, omapfb or any other driver should not be allowed to change the timings. So bpps sent via bootargs will not have an effect. In such case we can check only the x_res and y_res with the panels resolution and if they match go ahead and set the bpps. The bpp value sent via bootarg would have an effect.

2011-03-11OMAP: DSS2: Delay regulator_get() callsTomi Valkeinen
DSS submodules DPI/SDI/DSI/VENC require a regulator to function. However, if the board doesn't use, say, SDI, the board shouldn't need to configure vdds_sdi regulator required by the SDI module. Currently the regulators are acquired when the DSS driver is loaded. This means that if the kernel is configured with SDI, vdds_sdi regulator is needed for all boards. This patch changes the DSS driver to acquire the regulators only when a display of particular type is initialized. For example, vdds_sdi is acquired when sdi_init_display() is called.

2011-03-07drm/i915: Disable GPU semaphores by defaultChris Wilson
Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09 down to the use of GPU semaphores, and we already know that they appear broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.
