maintainerPATCH 1/10 OMAP: iommu: fix wrong argument in flush_cache_vmap()
From: Hiroshi DOYU <[email protected]>
The second argument should be the end address, not the length. Actually there will not be any effect on the behavior of this driver since flush_cache_vmap() calls flush_cache_all() in the end.

maintainerPATCH 3/10 OMAP2/3: Pass irqflags to 8250 driver
In reply to Tony LindgrenFrom: Vikram Pandita <[email protected]>
Pass irqflags to 8250 driver with platform_data. At least Zoom2 has IRQF_TRIGGER_RISING requirement for the 8250 GPIO irq.
This patch is dependent on 8250 driver changes getting accepted upstream:

maintainerPATCH 4/10 OMAP3: 3430SDP: Fix defconfig
In reply to Tony LindgrenFrom: Sergio Aguirre <[email protected]>
This patch makes the SDP boot again with the defconfig.
Changes done:
- Removes other selected boards.
- Sets the Low Level debug output for UART1.
- Disables some paripherals from other boards.
Tested on a SDP3430-VE5.1.0 (OMAP3430 ES3.1)

could you updated the patch to add that as well ??
Updated. Maybe take a look and see if the USB options make sense to you? I could not enable OTG for some reason..
Probably because OTG depends on
CONFIG_PMI think.

The second argument should be the end address, not the length. Actually there will not be any effect on the behavior of this driver since

Having printks which issue a level, followed by a newline, message and omitting the newline at the end looks really wrong:
- firstly, the KERN_WARNING "\n" line creates a blank line in the kernel message log.
- the message itself will be at the kernels default message level
- the following kernel message will be appended to the end, with any level tag exposed.
So I think the above printk statements are completely wrong and broken.

Hi,
I checked this defconfig at it's commit5dc8c8ffb27d93533d71493ca4a419f0290a3b2f
with the following:
1. Brought omap3_beagle_defconfig forward to 2.6.31-rc5 level. (via make gconfig)
2. Enabled CONFIG_PM, CONFIG_USB_MUSB_OTG, and
CONFIG_USB_GADGET_MUSB_HDRC with associated
default subchoices. (via make gconfig)
3. Removed 1 line work in progress? from arch/arm/mach-omap2/serial.c
4. Added previously posted (but not committed) patch for drivers/usb/otg/twl4030-usb.c
I was able to boot through INIT.
The diffs are against the 2.6.31-rc5 generated
version of omap3_beagle_defconfig.
Hope this helps.

- firstly, the
KERN_WARNING"\n" line creates a blank line in the kernel message log.
- the message itself will be at the kernels default message level
- the following kernel message will be appended to the end, with any level tag exposed.So I think the above printk statements are completely wrong and broken.
I've updated the patch to change the printk statements to just comments.

For OMAP3 add MMC1 MMC2 pin mux MMC3 mux is not added as there are multiple configurations possible, so the muxing is left to be done in board file.

1. Brought
omap3_beagle_defconfigforward to 2.6.31-rc5 level. (via make gconfig)2. Enabled
CONFIG_PM,CONFIG_USB_MUSB_OTG, and
CONFIG_USB_GADGET_MUSB_HDRCwith associated
default subchoices. (via make gconfig)
Great!

Yes, the related change is still in for-next, seem that it's going in when the merge window opens.

4. Added previously posted (but not committed) patch for

Felipe, can you please check if you have the twl4030-usb.c fix queued up?

The diffs are against the 2.6.31-rc5 generated

Subject: [PATCH] OMAP3: update OMAP3 Beagle defconfig
Update the OMAP3 Beagle defconfig to add EHCI, MMC, TWL4030 GPIO support. Beagle can again use MMC rootfs after this patch. Tested on BeagleBoard rev C2.
Patch updated to enable PM and OTG options as suggested by Eric Witcher <[email protected]>.

Right.
I have attached the updated version which limits max write counts to avoid the above buffer overflow.
Thanks, I've update my queue with it.
I'm not sure the patch is correct yet. I think this update introduced some bugs. Consider the debug_read_* functions and consider what happens if count = 1 but ppos != 0.

I think that "simple_read_from_buffer()" can take care of the above parameter checking?
