2009-03-24ARM: OMAP3: mmc-twl4030 voltage cleanupDavid Brownell4-48/+84
Correct twl4030 MMC power switching: fix voltage ranges reported for each slot, and handle them fully. Lies corrected: - MMC-1 doesn't support the 2.6-2.7 Volt range - MMC-2 can't normally support anything except 1.8V Omissions corrected - MMC-1 *does* handle the 2.8-2.9 Volt range - MMC-2 can handle 2.5-3.2 Volt cards, given a transceiver Add transciever support for MMC-2; enable it for Overo and Pandora. (Depends on something else to have set up pinmuxing for control signals instead of as MMC2_DAT4..7 pins.) Also shrink twl4030_hsmmc_info a smidgeon ... padding is all gone.

2009-03-24ARM: OMAP3: Add more GPIO mux optionsTony Lindgren2-0/+40
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>.

2009-03-24ARM: OMAP3: Remove unused CONFIG_I2C2_OMAP_BEAGLEJarkko Nikula1-3/+0

2009-03-24ARM: OMAP: get rid of OMAP_TAG_USB, v2Felipe Balbi17-46/+56
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>
2009-03-24ARM: OMAP: Dispatch only relevant DMA interruptsSantosh Shilimkar1-1/+3
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.

2009-03-24ARM: OMAP: Get available DMA channels from cmdlineSantosh Shilimkar1-1/+19
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.

2009-03-24ARM: OMAP: Add method to register additional I2C busses on the command line, v2Jarkko Nikula1-21/+52
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.

2009-03-24ARM: OMAP: Add command line option for I2C bus speed, v2Jarkko Nikula1-10/+44
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.

2009-03-19sparc64: Fix crash with /proc/iomemMikulas Patocka1-1/+1
When you compile kernel on Sparc64 with heap memory checking and type "cat /proc/iomem", you get a crash, because pointers in struct resource are uninitialized. Most code fills struct resource with zeros, so I assume that it is responsibility of the caller of request_resource to initialized it, not the responsibility of request_resource functuion. After 2.6.29 is out, there could be a check for uninitialized fields added to request_resource to avoid crashes like this. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: David S.

2009-03-18[S390] make page table upgrade work againMartin Schwidefsky2-14/+35
After TASK_SIZE now gives the current size of the address space the upgrade of a 64 bit process from 3 to 4 levels of page table needs to use the arch_mmap_check hook to catch large mmap lengths. The get_unmapped_area* functions need to check for -ENOMEM from the arch_get_unmapped_area*, upgrade the page table and retry. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-03-18[S390] make page table walking more robustMartin Schwidefsky3-5/+6
Make page table walking on s390 more robust. The current code requires that the pgd/pud/pmd/pte loop is only done for address ranges that are below the end address of the last vma of the address space. But this is not always true, e.g. the generic page table walker does not guarantee this. Change TASK_SIZE/TASK_SIZE_OF to reflect the current size of the address space. This makes the generic page table walker happy but it breaks the upgrade of a 3 level page table to a 4 level page table. To make the upgrade work again another fix is required.
