2010-10-29MIPS: Add platform device and Kconfig for Octeon USB EHCI / OHCIDavid Daney2-1/+106
Declare that OCTEON reference boards have both OHCI and EHCI. Add platform devices for the corresponding hardware.

2010-10-29USB: Add EHCI and OHCH glue for OCTEON II SOCs.David Daney7-2/+645
The OCTEON II SOC has USB EHCI and OHCI controllers connected directly to the internal I/O bus. This patch adds the necessary 'glue' logic to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II. The OCTEON normally runs big-endian, and the ehci/ohci internal registers have host endianness, so we need to select USB_EHCI_BIG_ENDIAN_MMIO. The ehci and ohci blocks share a common clocking and PHY infrastructure. Initialization of the host controller and PHY clocks is common between the two and is factored out into the octeon2-common.c file. Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in arch/mips/Kconfig in a following patch.

2010-10-29MIPS: Octeon: Apply CN63XXP1 errata workarounds.David Daney4-5/+69
The CN63XXP1 needs a couple of workarounds to ensure memory is not written in unexpected ways. All PREF with hints in the range 0-4,6-24 are replaced with PREF 28. We pass a flag to the assembler to cover compiler generated code, and patch uasm for the dynamically generated code. The write buffer threshold is reduced to 4.

2010-10-29MIPS: Octeon: Rewrite DMA mapping functions.David Daney6-301/+389
All Octeon chips can support more than 4GB of RAM. Also due to how Octeon PCI is setup, even some configurations with less than 4GB of RAM will have portions that are not accessible from 32-bit devices. Enable the swiotlb code to handle the cases where a device cannot directly do DMA. This is a complete rewrite of the Octeon DMA mapping code.

2010-10-29MIPS: Convert DMA to use dma-mapping-common.hDavid Daney8-153/+136
Use asm-generic/dma-mapping-common.h to handle all DMA mapping operations and establish a default get_dma_ops() that forwards all operations to the existing code. Augment dev_archdata to carry a pointer to the struct dma_map_ops, allowing DMA operations to be overridden on a per device basis. Currently this is never filled in, so the default dma_map_ops are used. A follow-on patch sets this for Octeon PCI devices. Also initialize the dma_debug system as it is now used if it is configured.

2010-10-29MIPS: Get rid of branches to .subsections.Ralf Baechle5-297/+243
It was a nice optimization - on paper at least. In practice it results in branches that may exceed the maximum legal range for a branch. We can fight that problem with -ffunction-sections but -ffunction-sections again is incompatible with -pg used by the function tracer. By rewriting the loop around all simple LL/SC blocks to C we reduce the amount of inline assembler and at the same time allow GCC to often fill the branch delay slots with something sensible or whatever else clever optimization it may have up in its sleeve. With this optimization gone we also no longer need -ffunction-sections, so drop it. This optimization was originally introduced in 2.6.21, commit 5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp. f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f (kernel.org).

2010-10-29watchdog: iTCO_wdt.c: remove extra pci_dev_put()'s from init codePrarit Bhargava1-2/+0
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove to fail because of an incorrect usage count. The probe for this driver does a for_each_pci_dev() which gets a reference for a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop puts a reference for a pci_dev when iTCO_wdt_init() fails, so the iTCO_wdt_init() does not need to do any pci_dev_put()'s. The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function. Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2010-10-29mfd: Fix off-by-one value range checking for tps6507xAxel Lin1-1/+1
If bytes == (TPS6507X_MAX_REGISTER + 1), we have a buffer overflow when doing memcpy(&msg[1], src, bytes). Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-10-29mfd: Remove __devinitdata from tc6393xb_mmc_resourcesMarek Vasut1-1/+1
This static struct resource tc6393xb_mmc_resources[] is used in resume function, therefore the data can not be wiped after init. Also, this causes a section mismatch.

2010-10-29mfd: Factor out WM831x I2C I/O from the core driverMark Brown6-139/+171
In preparation for the addition of SPI support for the WM831x move the I2C specific code into a separate file with a separate Kconfig option so the I2C support can be excluded from the build. Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new symbol. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
