| * | | OMAP3: DMA: Errata i541: sDMA FIFO draining does not finishPeter Ujfalusi2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | omap: dma: Fix buffering disable bit setting for omap24xxJarkko Nikula2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

The primary motivation for doing this is to move the OMAP2+-specific parts into an OMAP2+-specific file, so that build breakage related to the System Control Module code can be resolved.

| * | | OMAP: McBSP: implement functional clock switching via clock frameworkPaul Walmsley2010-10-08

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.

| * | | OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.cPaul Walmsley2010-10-08

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.

For OMAP4, the register offset appending of 0x100 done in devices.c currently, is moved to driver file.This change fits in for current implementation as well as once the driver undergoes hwmod adaptation.

The mux code manages the pad core and pad wakeup related base address inside the mux framework. For other usage only control core and control pad bases are necessary. So this patch maps only needed pad control base address which is used by device drivers and infrastructure code The main control core base is still kept same in this patch to keep git-bisect working.

This bug gets exposed only when passing multiple hwmod structures to omap_device_build_ss() resulting in incorrect extraction from second hwmod structure. This fix uses the pointer to pointer to omap_hwmod structure (array of pointers to omap_hwmod structure) passed to omap_device_build_ss() to correctly extract the appropriate omap_hwmod structure.
