2010-12-16MSM: Add USB support for MSM7x30Pavankumar Kondeti
Add USB OTG, peripheral and host devices. This patch also adds usb_phy_clk which is required for resetting the PHY. VBUS power up and shutdown routines depends on PMIC module. As PMIC driver is unavailable, configure USB in peripheral only mode. Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-16MSM: Add USB suport for QSD8x50Pavankumar Kondeti
OTG driver takes care of putting hardware into low power mode. Hence make peripheral and host devices as children of OTG device and let runtime PM takes care of notifying peripheral and host state to OTG device. VBUS power up and shutdown routines are implemented by modem processor. As RPC infrastructure is not available, configure USB in peripheral only mode.

2010-12-15msm: initial framebuffer supportDaniel Walker
Initial framebuffer components. Add board-trout-panel.c as well as platform parts to enable the framebuffer. This code comes directly from Google's tree. Signed-off-by: Daniel Walker <dwalker@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-15msm: add handling for clocks tagged as CLK_MINMAXDaniel Walker
CLK_MINMAX is used to denote clocks that have a wide variation in possible frequencies. This handling just sets the min and max values to the same value. Signed-off-by: Daniel Walker <dwalker@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-15msm: trout: change name of pmdh_clk to mddi_clkDaniel Walker
This clock is used in the framebuffer driver as mddi_clk. This just changes the name to match that. This also mirrors a change in Google tree. Signed-off-by: Daniel Walker <dwalker@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-15msm: add CLK_MINMAX to pmdh_clkDaniel Walker
This adds in the CLK_MINMAX flag to the pmdh_clk since it's actual a min/max clock instead of a single frequency clock. Signed-off-by: Daniel Walker <dwalker@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-15msm: trout: add gpio_to_irqDaniel Walker
trout has gpiolib support and interrupt support, but was missing the gpio_to_irq function. This adds that functions which should allow proper translation. Signed-off-by: Daniel Walker <dwalker@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-15msm: iommu: Use the correct memory allocation flagStepan Moskovchenko
Change msm_iommu_map to use GFP_ATOMIC instead of GFP_KERNEL due to the fact that the call occurs within a spinlock-protected region. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-09msm_serial: Remove redundant unlikely()Tobias Klauser
IS_ERR() already implies unlikely(), so it can be omitted here. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: David Brown <davidb@codeaurora.org>
2010-12-01msm: iommu: Miscellaneous code cleanupStepan Moskovchenko
Remove some unneeded assignments and messages, restructure a failure path in iova_to_phys, and make __flush_iotlb return int in preparation for adding IOMMU clock control. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-12-01msm: iommu: Support cache-coherent memory accessStepan Moskovchenko
Add support for allowing IOMMU memory transactions to be cache coherent, eliminating the need for software cache management in certain situations. This can lead to improvements in performance and power usage, assuming the multimedia core's access pattern exhibits spatial locality and that its working set fits into the cache.

2010-12-01msm: iommu: Definitions for extended memory attributesStepan Moskovchenko

2010-12-01msm: iommu: Check if device is already attachedStepan Moskovchenko
An IOMMU device can only be attached to one IOMMU domain at any given time. Check whether the device is already attached to a domain before allowing it to be attached to another domain. If so, return busy. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-12-01msm: iommu: Kconfig item for cacheable page tablesStepan Moskovchenko
Add a Kconfig item to allow the IOMMU page tables to be coherent in the L2 cache. This generally reduces IOTLB miss latencies and has been shown to improve multimedia performance. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-11-30msm: iommu: Don't flush page tables if no devices attachedStepan Moskovchenko
Don't flush the page tables on an IOMMU domain if there are no IOMMU devices attached to the domain. The act of attaching to the domain will cause an implicit flush of those areas if the page tables are configured to not be L2 cacheable.

2010-10-31i2c-i801: Handle multiple instances instead of keeping global stateDavid Woodhouse

2010-10-31locks: let the caller free file_lock on ->setlease failureChristoph Hellwig
The caller allocated it, the caller should free it. The only issue so far is that we could change the flp pointer even on an error return if the fl_change callback failed. But we can simply move the flp assignment after the fl_change invocation, as the callers don't care about the flp return value if the setlease call failed.

On little-endian (like x86) this doesn matter, but on a big-endian machine the 32-bit reads will see the (zero) high bits. Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT, which should be defined on all 64-bit arches.

2010-10-31nfsd4: initialize delegation pointer to leaseJ. Bruce Fields
The NFSv4 server was initializing the dp->dl_flock pointer by the somewhat ridiculous method of a locks_copy_lock callback. Now that setlease uses the passed-in lock instead of doing a copy, dl_flock no longer gets set, resulting in the lock leaking on delegation release, and later possible hangs (among other problems). So, initialize dl_flock and get rid of the callback. Signed-off-by: J.
