* OMAPDSS: HDMI: define and dump CORE registers in correct orderArchit Taneja2012-05-09
| | | | | | | | | | | | The HDMI core register offset macros aren't defined in ascending order of their values, some of the offset macros are also redefined. The same issues occur when these core registers are dumped. Clean up the ordering of HDMI core registers and remove repeated registers in the definition in ti_hdmi_4xxx_ip.h and in ti_hdmi_4xxx_core_dump().

* OMAPDSS: HDMI: Fix ti_hdmi_4xxx_core_dumpArchit Taneja2012-05-09
| | | | | | | | | | | | | | | | | | | | | The function ti_hdmi_4xxx_core_dump has some bugs, the following mention the bugs and the solutions: - The macros DUMPCORE and DUMPCOREAV in ti_hdmi_4xxx_core_dump() use hdmi_pll_base() for the offsets needed to calculate register addresses, use functions hdmi_core_sys_base() amd hdmi_av_base() to calculate the correct offsets for CORE_SYS and CORE_AV registers. - Many of the CORE_AV registers use the DUMPCORE macro, and hence the register addresses are calculated incorrectly. Rename the current DUMPCOREAV macro as DUMPCOREAV2 as it takes 2 arguments to dump indexed CORE_AV registers, create a new macro called DUMPCOREAV which is now used for dumping non-indexed CORE_AV registers. Thanks to Ancy Tom <ancytom@gmail.com> for pointing out the issues. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAPDSS: DISPC: Correct DISPC functional clock usageChandrabhanu Mahapatra2012-05-03
| | | | | | | | | | DISPC_FCLK is incorrectly used as functional clock of DISPC in scaling calculations. So, DISPC_CORE_CLK replaces as functional clock of DISPC. DISPC_CORE_CLK is derived from DISPC_FCLK divided by an independent DISPC divisor LCD. Signed-off-by: Chandrabhanu Mahapatra <cmahapatra@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAPDSS: DISPC: Handle synclost errors in OMAP3Chandrabhanu Mahapatra2012-05-03
| | | | | | | | | | | | | | | | In OMAP3 DISPC video overlays suffer from some undocumented horizontal position and timing related limitations leading to SYNCLOST errors. Whenever the image window is moved towards the right of the screen SYNCLOST errors become frequent. Checks have been implemented to see that DISPC driver rejects configuration exceeding above limitations. This code was successfully tested on OMAP3. This code is written based on code written by Ville Syrjälä <ville.syrjala@nokia.com> in Linux OMAP kernel. Ville Syrjälä <ville.syrjala@nokia.com> had added checks for video overlay horizontal timing and DISPC horizontal blanking length limitations.

* OMAPDSS: DISPC: Enable predecimationChandrabhanu Mahapatra2012-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In OMAP3 and OMAP4, the DISPC Scaler can downscale an image up to 4 times, and up to 2 times in OMAP2. However, with predecimation, the image can be reduced to 16 times by fetching only the necessary pixels in memory. Then this predecimated image can be downscaled further by the DISPC scaler. The pipeline is configured to use a burst of size 8 * 128 bits which consists of 8 mini bursts of 16 bytes each. So, horizontal predecimation more than 16 can lead to complete discarding of such mini bursts. L3 interconnect may handover the bus to some other initiator and inturn delay the fetching of pixels leading to underflows. So, maximum predecimation limit is fixed at 16. Based on the downscaling required, a prior calculation of predecimation values for width and height of an image is done. Since, Predecimation reduces quality of an image higher priorty is given to DISPC Scaler for downscaling. This code was successfully tested on OMAP2, OMAP3 and OMAP4. Horizontal and vertical predecimation worked fine except for some synclost errors due to undocumented errata in OMAP3 which are fixed later and skewed images were seen on OMAP2 and OMAP3 during horizontal predecimation which will be addressed in the future patches. This code is based on code written by Lajos Molnar <lajos@ti.com> who had added predecimation support for NV12/YUV/rotated/SDMA buffers.

* OMAPDSS: DISPC: Use a common function to set manager timingsArchit Taneja2012-04-23
| | | | | | | | | | | | | | | | Currently, a LCD manager's timings is set by dispc_mgr_set_lcd_timings() and TV manager's timings is set by dispc_set_digit_size(). Use a common function called dispc_mgr_set_timings() which sets timings for both type of managers. We finally want the interface drivers to use an overlay manager function to configure it's timings, having a common DISPC function would make things cleaner. For LCD managers, dispc_mgr_set_timings() sets LCD size and blanking values, for TV manager, it sets only the TV size since blanking values don't exist for TV.

* OMAPDSS: DISPC/RFBI: Use dispc_mgr_set_lcd_timings() for setting lcd sizeArchit Taneja2012-04-23
| | | | | | | | | | | | The RFBI driver uses dispc_mgr_set_lcd_size() to set the width and height of the LCD manager. Replace this to use dispc_mgr_set_lcd_timings(), pass dummy blanking parameters like done in the DSI driver. This prevents the need to export dispc_mgr_set_lcd_size(), and use a common function to set lcd timings.

* OMAP: DSS2: Remove suspicous and unused TAAL regulator API usageMark Brown2012-04-23
| | | | | | | | | | | | | | | | | | | | The TAAL driver contains some regulator support which is currently unused (the code is there but the one panel supported by the driver doesn't have any regulators provided). This code mostly looks like an open coded version of the regulator core bulk API. The only additional feature is that a voltage range can be set once when the device is opened, though this is never varied at runtime. The general expectation is that if the device is not actively managing the voltage of the device (eg, doing DVFS) then any configuration will be done using the constraints rather than by drivers, saving them code and ensuring that they work well with systems where the voltage is not configurable. If systems are added needing regulator support this can be added back in, though it should be based on core features rather than open coding things.

* OMAPDSS: DSI: remove option to use pck for DSI PLL clkinTomi Valkeinen2012-04-23
| | | | | | | | | | | | | For some OMAP versions the TRM says that the pixel clock from DISPC can be used as an input clock for DSI PLL, instead of the default, which is sysclk. For some OMAP versions the bits affecting this are marked as reserved. This feature has never been tested, so it's unknown if the HW even works, and has never been used. To clean things up, this patch removes the functionality. This should not affect any board. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* OMAPDSS: Ensure OPP100 when DSS is operationalTomi Valkeinen2012-04-23
| | | | | | | | | | | | | | | | | | | | | | Most of the DSS clocks have restrictions on their frequency based on the OPP in use. For example, maximum frequency for a clock may be 180MHz in OPP100, but 90MHz in OPP50. This means that when a high enough pixel clock or function clock is required, we need to use OPP100. However, there's currently no way in the PM framework to make that kind of request. The closest we get is to ask for very high bus throughput from the PM framework, which should effectively force OPP100. This patch is a simple version for handling the problem. Instead of asking for OPP100 only when needed, this patch asks for OPP100 whenever DSS is active. This obviously is not an optimal solution for cases with small displays where OPP50 would work just fine. However, a proper solution is a complex one, and this patch is a short term solution for the problem.

Of course, in the long term, removing omap_{read,write}l() is the appropriate thing to do; but this will take some work to do this cleanly. Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion to platform devices) that dangerously moved code and changed it in the same patch.

This will lead to missing the module wakeup on OMAP's where the smart idle wakeup is supported. This was the root cause of the console sluggishness issue, I have been observing on OMAP4 devices and also can be potential reason for some other UART wakeup issues.

| | * | | ARM: OMAP2+: UART: Fix incorrect population of default uart padsGovindraj.R2012-04-17

This causes breakage on multiple boards using uart pins for alternate functions. For example, on zoom3 random oopses can be seen with nfsroot as the smsc911x ethernet FIFO timings on GPMC bus are controlled by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these pads to uart4 functionality as commit 7496ba3 was doing. Not all boards tend to use all uarts and most of unused uart pins are muxed for other purpose. This commit breaks the modules which where trying to use unused uart pins on their boards. So remove the default pad muxing. Note that this is not a complete fix, as we now rely on bootloader set muxing for the uart wake-up events. Further patching is needed to enable wake-up events for uarts that are already muxed to uart mode.
