2012-10-01dt: Document general interrupt controller bindingsThierry Reding
In order to use a device as interrupt controller, it needs to be marked with the DT interrupt-controller property. This commit adds rudimentary documentation about the required standard properties and describes the most commonly used interrupt specifiers.

Pull GFS2 updates from Steven Whitehouse: "The major feature this time is the "rbm" conversion in the resource group code. The new struct gfs2_rbm specifies the location of an allocatable block in (resource group, bitmap, offset) form. There are a number of added helper functions, and later patches then rewrite some of the resource group code in terms of this new structure. Not only does this give us a nice code clean up, but it also removes some of the previous restrictions where extents could not cross bitmap boundaries, for example. In addition to that, there are a few bug fixes and clean ups, but the rbm work is by far the majority of this patch set in terms of number of changed lines." * git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw: (27 commits) GFS2: Write out dirty inode metadata in delayed deletes GFS2: fix s_writers.counter imbalance in gfs2_ail_empty_gl GFS2: Fix infinite loop in rbm_find GFS2: Consolidate free block searching functions GFS2: Get rid of I_MUTEX_QUOTA usage GFS2: Stop block extents at the end of bitmaps GFS2: Fix unclaimed_blocks() wrapping bug and clean up GFS2: Improve block reservation tracing GFS2: Fall back to ignoring reservations, if there are no other blocks left GFS2: Fix ->show_options() for statfs slow GFS2: Use rbm for gfs2_setbit() GFS2: Use rbm for gfs2_testbit() GFS2: Eliminate unnecessary check for state > 3 in bitfit GFS2: Eliminate redundant calls to may_grant GFS2: Combine functions gfs2_glock_dq_wait and wait_on_demote GFS2: Combine functions gfs2_glock_wait and wait_on_holder GFS2: inline __gfs2_glock_schedule_for_reclaim GFS2: change function gfs2_direct_IO to use a normal gfs2_glock_dq GFS2: rbm code cleanup GFS2: Fix case where reservation finished at end of rgrp ...

2012-10-01dt: introduce of_get_child_by_name to get child node by nameSrinivas Kandagatla
This patch introduces of_get_child_by_name function to get a child node by its name in a given parent node. Without this patch each driver code has to iterate the parent and do a string compare, However having of_get_child_by_name libary function would avoid code duplication, errors and is more convenient.

2012-10-01spi: remove completely broken Tegra driverStephen Warren
The current SPI driver has many issues. Examples are: * Segfaulting on most transfers due to expecting all transfers to have both RX and TX buffers. * Hanging on TX transfers since the whole driver flow is driven by RX DMA completion, but the HW is only told to enable RX for RX transfers. * Use of clk_disable_unprepare() from atomic context. * Once those and other minor issues are fixed, the driver still doesn't actually work. * The driver also implements a deprecated API to the SPI core. For this reason, simply remove the driver completely. This has two advantages: 1) This will remove the last use of Tegra's <mach/dma.h>, which will allow that file to be removed, which is required for single zImage work. 2) The downstream driver is significaly different from the current code. I believe a patch to re-add the downstream driver (with appropriate cleanup) will be much simpler to review if it's a new file rather than randomly interspered with essentially unrelated existing code.

2012-10-01MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLsGabor Juhos
Besides the CPU and DDR PLLs, the CPU and DDR frequencies can be derived from other PLLs in the SRIF block on the AR934x SoCs. The current code does not checks if the SRIF PLLs are used and this can lead to incorrectly calculated CPU/DDR frequencies. Fix it by calculating the frequencies from SRIF PLLs if those are used on a given board.

2012-10-01MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934xGabor Juhos
The current dividers in the code are wrong and this leads to broken CPU frequency calculation on boards where the fractional part is used. For example, if the SoC is running from a 40MHz reference clock, refdiv=1, nint=14, outdiv=0 and nfrac=31 the real frequency is 579.375MHz but the current code calculates 569.687MHz instead. Because the system time is indirectly related to the CPU frequency the broken computation causes drift in the system time. The correct divider is 2^6 for the CPU PLL and 2^10 for the DDR PLL. Use the correct values to fix the issue.

2012-10-01MIPS: BCM63XX: Properly handle mac address octet overflowJonas Gorski
While calculating the mac address the pointer for the current octet was never reset back to the least significant one after being decremented because of an octet overflow. This resulted in the code continuing to increment at the current octet, potentially generating duplicate or invalid mac addresses. As a second issue the pointer was allowed to advance up to the most significant octet, modifying the OUI, and potentially changing the type of mac address. Rewrite the code so it resets the pointer to the least significant in each outer loop step, and bails out when the least significant octet of the OUI is reached.

2012-10-01mlx4_core: Disable SENSE_PORT for multifunction devicesRoland Dreier
In the current driver, the SENSE_PORT firmware command is issued as a "wrapped" command, but the command handling code doesn't have a wrapper, so it will never do anything other than log an error message. The latest ConnectX-3 2.11.500 firmware reports the SENSE_PORT capability even in multi-function (SR-IOV) mode, so the driver will try to issue the command. At least until the driver has a proper wrapper for SENSE_PORT, make sure we disable the command for multi-function devices. Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-10-01mlx4_core: Clean up enabling of SENSE_PORT for older (ConnectX-1/-2) HCAsRoland Dreier
