* ARM: OMAP3: Add more GPIO mux optionsTony Lindgren2009-03-23
| | | | | | | | | | | | This patch adds several new GPIO pins and updates the pin naming comments. The patch is based on earlier patches on linux-omap list by Manikandan Pillai <mani.pillai@ti.com>, Vaibhav Hiremath <hvaibhav@ti.com> and David Brownell <dbrownell@users.sourceforge.net>.

* ARM: OMAP: get rid of OMAP_TAG_USB, v2Felipe Balbi2009-03-23
| | | | | | | | | | | | | | | | 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>. Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP: Dispatch only relevant DMA interruptsSantosh Shilimkar2009-03-23
| | | | | | | | | | | | | | | | | | | 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.

* ARM: OMAP: Get available DMA channels from cmdlineSantosh Shilimkar2009-03-23
| | | | | | | | | | | | | 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.

* ARM: OMAP: Add method to register additional I2C busses on the command line, v2Jarkko Nikula2009-03-23
| | | | | | | | | | | | | 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 to external connectors only without any on board I2C devices.

* ARM: OMAP: Add command line option for I2C bus speed, v2Jarkko Nikula2009-03-23
| | | | | | | | | | | | | | | 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.

| * [ARM] Fix virtual to physical translation macro corner casesRussell King2009-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current use of these macros works well when the conversion is entirely linear. In this case, we can be assured that the following holds true: __va(p + s) - s = __va(p) However, this is not always the case, especially when there is a non-linear conversion (eg, when there is a 3.5GB hole in memory.) In this case, if 's' is the size of the region (eg, PAGE_SIZE) and 'p' is the final page, the above is most definitely not true. So, we must ensure that __va() and __pa() are only used with valid kernel direct mapped RAM addresses. This patch tweaks the code to achieve this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fix for the following crash observed in 2.6.29-rc3: http://lkml.org/lkml/2009/1/29/150 On ARM it doesn't make sense to trace a naked function because then mcount is called without stack and frame pointer being set up and there is no chance to restore the lr register to the value before mcount was called.
