2014-02-11OMAPDSS: fix fck field typesTomi Valkeinen
'fck' field in dpi and sdi clock calculation struct is 'unsigned long long', even though it should be 'unsigned long'. This hasn't caused any issues so far. Fix the field's type. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-02-11OMAPDSS: DISPC: decimation rounding fixTomi Valkeinen
The driver uses DIV_ROUND_UP when calculating decimated width & height. For example, when decimating with 3, the width is calculated as: width = DIV_ROUND_UP(width, decim_x); This yields bad results for some values. For example, 800/3=266.666..., which is rounded to 267. When the input width is set to 267, and pixel increment is set to 3, this causes the dispc to read a line of 801 pixels, i.e. it reads a wrong pixel at the end of the line. Even more pressing, the above rounding causes a BUG() in pixinc(), as the value of 801 is used to calculate row increment, leading to a bad value being passed to pixinc(). This patch fixes the decimation by removing the DIV_ROUND_UP()s when calculating width and height for decimation. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

However, it misses the logic found in Nokia kernels that is needed to correctly calculate whether 3 tap or 5 tap rescaler to be used as well as the logic to fallback to 3 taps if 5 taps clock results in too tight horizontal timings.

2014-01-13OMAPDSS: panel-acx565akm: clean-up lockingTomi Valkeinen
The locking in the acx565akm panel driver was getting too complex. Clean it up by making new functions, acx565akm_bl_get_intensity_locked and acx565akm_bl_update_status_locked, which are called by the backlight subsystem. This way the non-locked versions can be called by the panel's other funcs, simplifying the lock management. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-01-13OMAPDSS: DISPC: Preload more data in pipeline DMAs for OMAP4+ SoCsArchit Taneja
DISPC pipeline DMAs preload some bytes of pixel data in the vertical blanking region before the start of each frame. The preload ensures the pipeline doesn't underflow when the active region of the display starts. DISPC_GFX/VIDp_PRELOAD registers allow us to program how many bytes of data should be preloaded for each pipeline. Calculating a precise preload value would be a complex function of the pixel clock of the connected display, the vertical blanking duration and the interconnect traffic at that instance. If the register is left untouched, a default value is preloaded. We observe underflows for OMAP4+ SoCs for certain bandwidth intensive use cases with many other initiators active, and in situations where memory access isn't very efficient(like accessing Tiler mapped buffers and EMIF configured in non-interleaved more). The cause of the underflow is because the default preload value isn't sufficient for the DMA to reach a steady state. We configure the PRELOAD register such that the pipelines preload data up to the high threshold of the FIFO. Preloading lot of data for older SoCs can have a negative impact. Due to slower interconnects, it's possible that the DISPC DMA cannot preload up to the high threshold within the vertical blanking region of the panel. We leave the PRELOAD registers to their reset values since we haven't faced underflows with these SoCs because of low value of PRELOAD.

2014-01-13OMAPFB: disable overlays on driver removalTomi Valkeinen
When omapfb module is removed, the driver will turn off all the displays it manages. However, it leaves the overlays enabled. While the overlays are obviously disabled as the displays are disabled, it causes issues when the driver module is loaded again, as at that point the overlays are still enabled on the hardware level. The result is that even if the SW thinks overlays are disabled, they are actually enabled. Fix this by making sure the overlays are disabled at module removal.

2014-01-13OMAPDSS: don't print errors on -EPROBE_DEFERTomi Valkeinen
Nowadays it's normal to get -EPROBE_DEFER from, e.g., regulator_get. As -EPROBE_DEFER is not really an error, and the driver will be probed fine a bit later, printing an error message will just confuse the user. This patch changes omapdss to print an error for regulator_gets only if the error code is something else than -EPROBE_DEFER. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-01-13OMAPFB: give informative print when probe succeedsTomi Valkeinen
It is quite common to have omapfb probe deferred because of a missing resource, and to get omapfb probed succesfully a bit later. This works fine. However, omapfb does not give any print on a successful probe, so if the omapfb is actually never probed again after deferral, this is not shown in the log. To help debugging, add a simple print from omapfb at the end of its probe, saying which display it is using and in which resolution. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-01-13OMAPDSS: HDMI: rename resource namesTomi Valkeinen
The HDMI driver tries to get the needed memory resources by name and by ID. Resources by name are not currently defined, and will be used with DT boot. The resource names used in the driver are not quite perfect, and as they are not used yet, we can change them. This patch removes the unneeded "hdmi_" prefix from the names, and simplifies the names (e.g. hdmi_txphy -> phy). Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-01-13OMAPDSS: DSI: split DSI memory map to smaller blocksTomi Valkeinen
DSI contains three separate blocks: protocol engine, PHY and PLL. At the moment, all these are memory mapped in one big chunk. We need to split that memory map into smaller pieces so that we can add proper 'reg' properties into the DT data for each block. This patch changes the driver to map the blocks separately. It first tries to get the memory resource using name, used when booting with DT, and if that fails, it gets the memory resource by ID, in which case the driver gets the big chunk from platform data. That big chunk is then split into the smaller blocks manually. After DSS DT code has been merged and the old platform code removed, we can clean up the memory resource management. Instead of changing the driver in all the places where a register is read or written, this patch takes a shortcut: it adds an additional number to the struct which represents the register index. This number is used to decide which base address to use. In the future we should consider other approaches. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

hdmi_wait_for_bit_change() has two issues: The register index was passed as u16, even if the register index may be u32. Fix the index to u32. The function was copied from wait_for_bit_change() which waits for a single bit to change, but the hdmi version was changed to wait for a bit field. This change was not done correctly. The function is supposed to return the (last) value of the bit field, but it returned !val in case of timeout. This was correct for the single bit version, but not for the hdmi version. Fix the function to return the actual value in the register. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-01-13OMAPDSS: DISPC: fix context restoreTomi Valkeinen
DISPC_MSTANDBY_CTRL register is used in the driver, but it's not restored in dispc_restore_context(), causing problems after resume. Instead of adding DISPC_MSTANDBY_CTRL to dispc_restore_context(), let's call _omap_dispc_initial_config() as the first thing in dispc_runtime_resume(). This will initialize the DISPC core registers properly, and will avoid similar issues in the future. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2014-01-13OMAPDSS: HDMI4: Accept non-standard timingsArchit Taneja
The hdmi4 driver currently rejects any timing which is not from the CEA or VESA standards. This leads hdmi rejecting any non-standard mode. A non standard timing may not have a valid code corresponding to it. In such cases, the HDMI spec suggests to set the code to 0.

2014-01-09drm/omap: fix (un)registering irqs inside an irq handlerTomi Valkeinen
omapdrm (un)registers irqs inside an irq handler. The problem is that the (un)register function uses dispc_runtime_get/put() to enable the clocks, and those functions are not irq safe by default. This was kind of fixed in 48664b21aeeffb40c5fa06843f18052e2c4ec9ef (OMAPDSS: DISPC: set irq_safe for runtime PM), which makes dispc's runtime calls irq-safe. However, using pm_runtime_irq_safe in dispc makes the parent of dispc, dss, always enabled, effectively preventing PM for the whole DSS module. This patch makes omapdrm behave better by adding new irq (un)register functions that do not use dispc_runtime_get/put, and using those functions in interrupt context. Thus we can make dispc again non-irq-safe, allowing proper PM. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Rob Clark <robdclark@gmail.com>

2013-12-30OMAPDSS: apply fixesTomi Valkeinen
When omapfb does ovl->get_overlay_info, ovl->set_overlay_info, the set function may fail even if the info has not been changed. This is because omapdss doesn't initialize the info, but expect the caller to set valid values. Normally that is the case, but there is at least one corner case: if omapfb has not allocated memory for the overlay yet, and the user uses ioctl to disable the overlay to make sure it's disabled. In this case get_overlay_info returns invalid data, but the user is only interested in setting the overlay to disabled, not configuring it, and set_overlay_info fails. The issue is made possible by the omapfb's setup_plane ioctl, which groups overlay configuration and overlay enable/disable bit into the same struct. Thus, when you are disabling an overlay, you are also configuring it. This is a bit counter intuitive, so I think it's better to initialize the info to some valid values. The fields requiring initialization are color_mode and rotation_type, and also we need to remove the check for (paddr == 0), as paddr is 0 for unallocated overlay (but it's still fine to disable the overlay).

HDMI PHY is a block common to DSS in OMAP4, OMAP5 and DRA7x. Move the existing functions from ti_hdmi_4xxx_ip.c to a separate file. These funcs are called directly from the hdmi driver rather than hdmi_ip_ops function pointer calls. Add the PHY library function declarations to ti_hdmi.h. These will be shared amongst the omap4/5 hdmi platform drivers. Remove the PHY function pointer ops from the ti_hdmi_ip_ops struct. The DT/hwmod information for hdmi doesn't split the address space according to the required sub blocks. Keep the address offset and size information in the driver for now. This will be removed when the driver gets the information correctly from DT/hwmod. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
