am3517: geting MMC working

[Yegor Yefremov]

What patches do I need to get MMC working with linux-omap master?

omap_hsmmc omap_hsmmc.0: Failed to get debounce clk
omap-dma-engine omap-dma-engine: allocating channel for 62
omap-dma-engine omap-dma-engine: allocating channel for 61
omap_hsmmc omap_hsmmc.1: Failed to get debounce clk
omap-dma-engine omap-dma-engine: allocating channel for 48
omap-dma-engine omap-dma-engine: allocating channel for 47

I searched for this issue and saw some patches for common clock framework that were scheduled for 3.6, but I'm not sure it's enough or weather they are already incorporated in linux-omap.

Best regards,
Yegor

I guess you need [1] to get around the issue.

though I haven't applied this patch I have DMA activated (CONFIG_DMADEVICES and CONFIG_DMA_OMAP). Found in some other thread [1]. As far as I can tell, debounce clk is the problem.

Debouce clocks failures are non fatal, and are present in OMAP2xxx only.
(I don't know about AM35xx, but most likely its not present).
The last 2 lines shows that mmc0 is enumerated, but the boot partition is not.
If possible, can you please provide logs with MMC_DEBUG enabled at compile time
and a verbose loglevel (loglevel=8) ?

Thanks,
Venkat.

Hi Yegor,

In case is of some help to you I had the exact problem than you on an
IGEPv2 board (TI DM3730 OMAP3 board)

But enabling CONFIG_DMA_OMAP and CONFIG_DMADEVICES solve it. Now on
booting I have this log:

[    2.312866] omap_hsmmc omap_hsmmc.1: Failed to get debounce clk
[    2.319335] omap-dma-engine omap-dma-engine: allocating channel for 48
[    2.326324] omap-dma-engine omap-dma-engine: allocating channel for 47
[    2.377716] omap_hsmmc omap_hsmmc.0: Failed to get debounce clk
[    2.384124] omap-dma-engine omap-dma-engine: allocating channel for 62
[    2.390991] omap-dma-engine omap-dma-engine: allocating channel for 61

and the MMC is working well.

Best regards,
Javier

From this, one can only infer that the card is not responding at all,
and all attempts
are returning with a timeout (CTO=Command Time Out).
These (control) commands don't use DMA, so it's not a DMA issue upto this.
If the card is fine, and it worked before, I would suggest a bisect.
Meanwhile I'll check lo-master with my OMAP4 boards.

I checked on 4430sdp, OMAP4 is able to detect both eMMC and SD with lo-master.

WIll bissect. Thanks for help.

Looks to me like the card is responding to CMD8, CMD55, ACMD41, and CMD0.  
It's only CMD52 and CMD5 that are timing out.  Aren't those timeouts 
expected with a SD memory card?

yes, those timeouts are expected for SD card.
The failure is due to irq not received/missing for last CMD0.
Hi Yegor, Can you provide details for the SD card being used.

This is Apacer 2GB. In 3.3-rc7 I have no problems with it. Should I enable debugging in 3.3-rc7 and post the output?

Best regards,

I found the solution:

diff --git a/arch/arm/mach-omap2/pm34xx.c b/arch/arm/mach-omap2/pm34xx.c
index e4fc88c..0ab26ab 100644
--- a/arch/arm/mach-omap2/pm34xx.c
+++ b/arch/arm/mach-omap2/pm34xx.c
@@ -359,7 +359,7 @@ static void omap3_pm_idle(void)
 {
 	local_fiq_disable();
 
-	if (omap_irq_pending())
+	if (omap_irq_pending() || !omap3_has_io_wakeup())
 		goto out;
 
 	trace_power_start(POWER_CSTATE, 1, smp_processor_id());

I've seen this hack for some on the mailing list. I think Mark A. Greer introduced it, but I don't remember for sure. Can this patch be applied as it is or there are some infrastructure changes required?

Best regards,

[Oops, I thought I sent this days ago.]

Hi Yegor.

Yep, it was me.  That change is unacceptable though, see:

	http://www.spinics.net/lists/arm-kernel/msg168865.html

You were testing on linux-omap/master?  If so, hmmm, I thought
that branch would work.  For now, you can try adding 'nohlt'
to the cmdline but that's a bit of a sledgehammer...
