2010-10-11OMAP3: DMA: Errata i541: sDMA FIFO draining does not finishPeter Ujfalusi2-2/+37
Implement the suggested workaround for OMAP3 regarding to sDMA draining issue, when the channel is disabled on the fly. This errata affects the following configuration: sDMA transfer is source synchronized Buffering is enabled SmartStandby is selected. The issue can be easily reproduced by creating overrun situation while recording audio. Either introduce load to the CPU: nice -19 arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null & \ dd if=/dev/urandom of=/dev/null or suspending the arecord, and resuming it: arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null CTRL+Z; fg; CTRL+Z; fg; ... In case of overrun audio stops DMA, and restarts it (without reseting the sDMA channel). When we hit this errata in stop case (sDMA drain did not complete), at the coming start the sDMA will not going to be operational (it is still draining). This leads to DMA stall condition. On OMAP3 we can recover with sDMA channel reset, it has been observed that by introducing unrelated sDMA activity might also help (reading from MMC for example). The same errata exists for OMAP2, where the suggestion is to disable the buffering to avoid this type of error. On OMAP3 the suggestion is to set sDMA to NoStandby before disabling the channel, and wait for the drain to finish, than configure sDMA to SmartStandby again.

2010-10-11omap: dma: Fix buffering disable bit setting for omap24xxJarkko Nikula2-4/+11
An errata workaround for omap24xx is not setting the buffering disable bit 25 what is the purpose but channel enable bit 7 instead. Background for this fix is the DMA stalling issue with ASoC omap-mcbsp driver. Peter Ujfalusi <peter.ujfalusi@nokia.com> has found an issue in recording that the DMA stall could happen if there were a buffer overrun detected by ALSA and the DMA was stopped and restarted due that. This problem is known to occur on both OMAP2420 and OMAP3. It can recover on OMAP3 after dma free, dma request and reconfiguration cycle. However, on OMAP2420 it seems that only way to recover is a reset. Problem was not visible before the commit c12abc0. That commit changed that the McBSP transmitter/receiver is released from reset only when needed. That is, only enabled McBSP transmitter without transmission was able to prevent this DMA stall problem in receiving side and underlying problem did not show up until now. McBSP transmitter itself seems to no be reason since DMA stall does not recover by enabling the transmission after stall. Debugging showed that there were a DMA write active during DMA stop time and it never completed even when restarting the DMA. Experimenting showed that the DMA buffering disable bit could be used to avoid stalling when using source synchronized transfers. However that could have performance hit and OMAP3 TRM states that buffering disable is not allowed for destination synchronized transfers so subsequent patch will implement a method to complete DMA writes when stopping. This patch is based on assumtion that complete lock-up on OMAP2420 is different but related problem. I don't have access to OMAP2420 errata but I believe this old workaround here is put for a reason but unfortunately a wrong bit was typed and problem showed up only now.

On OMAP3 the watchdog is generating reboot because devices_init doesn't happens where as on OMAP4 it just hangs without reboot. The uart clock is not getting enabled after omap_device_idle as part of omap_serial_init. The omap_device_idle(will disable the clock) then omap_uart_block_sleep() should enable clock back disabled during the boot up phase. But omap_uart_block_sleep() stuffed version is binded only under CONFIG_PM and other version is just empty. Hence it is not enabling clock back as expected This patch adds uart clock enable code to omap_uart_block_sleep() function built with CONFIG_PM disabled.

Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.

2010-10-08OMAP: McBSP: implement functional clock switching via clock frameworkPaul Walmsley3-3/+62
Previously the OMAP McBSP ASoC driver implemented CLKS switching by using omap_ctrl_{read,write}l() directly. This is against policy; the OMAP System Control Module functions are not intended to be exported to drivers. These symbols are no longer exported, so as a result, the OMAP McBSP ASoC driver does not build as a module. Resolve the CLKS clock changing portion of this problem by creating a clock parent changing function that lives in arch/arm/mach-omap2/mcbsp.c, and modify the ASoC driver to use it. Due to the unfortunate way that McBSP support is implemented in ASoC and the OMAP tree, this symbol must be exported for use by sound/soc/omap/omap-mcbsp.c. Going forward, the McBSP device driver should be moved from arch/arm/*omap* into drivers/ or sound/soc/* and the CPU DAI driver should be implemented as a platform_driver as many other ASoC CPU DAI drivers are. These two steps should resolve many of the layering problems, which will rapidly reappear during a McBSP hwmod/PM runtime conversions.

2010-10-08OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.cPaul Walmsley4-1/+45
The OMAP ASoC McBSP code implemented CLKR and FSR signal muxing via direct System Control Module writes on OMAP2+. This required the omap_ctrl_{read,write}l() functions to be exported, which is against policy: the only code that should call those functions directly is OMAP core code, not device drivers. omap_ctrl_{read,write}*() are no longer exported, so the driver no longer builds as a module. Fix the pinmuxing part of the problem by removing calls to omap_ctrl_{read,write}l() from the OMAP ASoC McBSP code and implementing signal muxing functions in arch/arm/mach-omap2/mcbsp.c. Due to the unfortunate way that McBSP support is implemented in ASoC and the OMAP tree, these symbols must be exported for use by sound/soc/omap/omap-mcbsp.c. Going forward, the McBSP device driver should be moved from arch/arm/*omap* into drivers/ or sound/soc/*, and the CPU DAI driver should be implemented as a platform_driver as many other ASoC CPU DAI drivers are.

2010-10-01OMAP1: Amstrad Delta: add support for cameraJanusz Krzysztofik1-0/+45
This patch adds configuration data and initialization code required for camera support to the Amstrad Delta board. Three devices are declared: SoC camera, OMAP1 camera interface and OV6650 sensor. Default 12MHz clock has been selected for driving the sensor. Pixel clock has been limited to get reasonable frame rates, not exceeding the board capabilities. Since both devices (interface and sensor) support both pixel clock polarities, decision on polarity selection has been left to drivers. Interface GPIO line has been found not functional, thus not configured. Signed-off-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-10-01omap4 hsmmc: Update ocr mask for MMC2 for regulator to usekishore kadiyala1-0/+1
On OMAP4, MMC2 controller has eMMC which draws power from VAUX regulator on TWL. Though the eMMC supports dual voltage[1.8v/3v] as per ocr register, its VCC is fixed at 3V for operation. With this once the mmc core selects the minimum voltage[1.8] supported based on the ocr value read from OCR register, eMMC will not get detected. Thus the platform data for MMC2 is updated with ocr mask and same will be communicated to core which will set the regulator to always operate at 3V when ever turned ON.
