[PATCH 0/7] Updates for common omap code for next merge window

[Tony Lindgren]

Hi,

This series contains updates for common omap code. Still to come
is a series of omap3 specific patches during this week.

Regards,

Tony

[PATCH 3/7] ARM: OMAP: Add command line option for I2C bus speed

[Tony Lindgren]

From: Jarkko Nikula <jarkko.nikula@nokia.com>

This patch adds a new command line option "i2c_bus=bus_id,clkrate" into
I2C bus registration helper. Purpose of the option is to override the
default board specific bus speed which is supplied by the
omap_register_i2c_bus.

The default bus speed is typically set to speed of slowest I2C chip on the
bus and overriding allow to use some experimental configurations or updated
chip versions without any kernel modifications.

Jarkko, this should also be in Documentation/kernel-parameters.txt. Can
you please reply with a patch for that, and I'll fold it into this
patch?

Also, maybe it should be called omap_i2c_bus instead of i2c_bus?

Tony

or maybe not, then other archs would have the opportunity to setup their
own function to handle i2c_bus= cmdline without having to add a brand
new <arch>_i2c_bus one ;-)

Ah, good, will do it over weekend - early next week. Probably better to
handle as a separate patch for easier merging with

I had similar thought as Felipe that it looks more generic this way.
But don't know now immediately would multibuild will work? Was that
your concern? E.g.

__setup("i2c_bus=", arm_xxx_i2c_bus_setup);
__setup("i2c_bus=", omap_i2c_bus_setup);

I think they should get merged as a single patch.

Well is it generic enough to work for everybody? And if so, we should
run it by the LKML and the linux-i2c lists.

Any comments from other ARM platforms?

[2.6.29-rc7][take #2][PATCH 0/3] ARM: OMAP: Add command line option for I2C bus speed

[Jarkko Nikula]

Hi

These patches are for linux-omap but we want to wide discussion also to
linux-i2c is the new command line option "i2c_bus=bus_id,clkrate" generic
enough to be used for other architectures as well in the future. Patches
are generated on top of mainline 2.6.29-rc7.

Purpose of this command line option is to both allow to override the default
board specific bus speed (patch 2) and register additional busses that
are not registered from board initialization code (patch 3).

Example for patch 2 would be the case where some on board component is upgraded
and which allows to use e.g. higher clock rate on the bus without other major
board changes.

Patch 3 can have more practical use however. E.g. second I2C bus on TI
BeagleBoard doesn't have on board components and thus it is not registered
by default with omap_register_i2c_bus. This bus is routed to expansion pin
header so with this patch it is able to register dynamically when needed.

These patches are previously discussed in these threads:

[2.6.29-rc7][take #2][PATCH 2/3] ARM: OMAP: Add command line option for I2C bus speed

[Jarkko Nikula]

This patch adds a new command line option "i2c_bus=bus_id,clkrate" into
I2C bus registration helper. Purpose of the option is to override the
default board specific bus speed which is supplied by the
omap_register_i2c_bus.

The default bus speed is typically set to speed of slowest I2C chip on the
bus and overriding allow to use some experimental configurations or updated
chip versions without any kernel modifications.

Thanks for updating this. I've updated my omap-upstream series with your

Yep, no changes in #1 and it can go anyway as it since it only adds a
bit documentation to the arch/arm/plat-omap/i2c.c.

However we haven't received any comments to the patches #2 and #3
adding new command line option "i2c_bus=bus_id,clkrate" so let's see do
they go :-)

[PATCH 4/7] ARM: OMAP: Add method to register additional I2C busses on the command line

From: Jarkko Nikula <jarkko.nikula@nokia.com>

This patch extends command line option "i2c_bus=bus_id,clkrate" so that
it allow to register additional I2C busses that are not registered with
omap_register_i2c_bus from board initialization code.

Purpose of this is to register additional board busses which are routed

[PATCH 5/7] ARM: OMAP: Get available DMA channels from cmdline

[Tony Lindgren]

From: Santosh Shilimkar <santosh.shilimkar@ti.com>

This patch set up a cmdline option for omap dma for masking the
available channels. It is needed since the OMAP DMA is a system wide
resource and can be used by another software apart from the kernel.

To reserve the omap SDMA channels for kernel dma usage, use cmdline
bootarg "omap_dma_reserve_ch=". The valid range is 1 to 32.

[PATCH 6/7] ARM: OMAP: Dispatch only relevant DMA interrupts

[Tony Lindgren]

From: Santosh Shilimkar <santosh.shilimkar@ti.com>

This fixes the spurious interrupt issue on a DMA channel.

In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the
SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of
the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers.
Since there are four sDMA interrupt lines and if more than one
line is actively used by two concurrently running sDMA softwares
modules,then the spurious interrupt can be observed on the other
lines.

Fix in this patch will only dispatch the relevant and enabled
interrupts on a particular line thus perevting spurious IRQ.

[PATCH 7/7] ARM: OMAP: get rid of OMAP_TAG_USB

[Tony Lindgren]

From: Felipe Balbi <felipe.balbi@nokia.com>

OMAP_TAGS should vanish soon since they're not generic arm tags.
Most of them can be converted to a platform_data or parsed
from a command line like e.g. serial tag.

For OMAP_TAG_USB we just let boards call omap_usb_init()
passing a pointer to omap_usb_config.

Patch updated by Tony for mainline, basically make
n770 and h4 compile.

Here's this one updated with a fix for OSK from Dave.

Subject: [PATCH] ARM: OMAP: get rid of OMAP_TAG_USB, v2

OMAP_TAGS should vanish soon since they're not generic arm tags.
Most of them can be converted to a platform_data or parsed
from a command line like e.g. serial tag.

For OMAP_TAG_USB we just let boards call omap_usb_init()
passing a pointer to omap_usb_config.

Patch updated by Tony for mainline, basically make
n770 and h4 compile. Also folded in a fix for OSK
by David Brownell <dbrownell@users.sourceforge.net>.
