2014-01-06ARM: shmobile: r8a7790: Fix I2C controller namesValentine Barshak
This fixes the issue introduced by the following commit: b448c904f5058b6c "ARM: shmobile: r8a7790: add I2C support" The R8A7790 is an R-Car Gen2 SoC. The clock division factor (CDF) width is 3 bits on Gen2 as opposed to 2 bits on Gen1. Fix the device names for R8A7790 SoC to make the R-Car I2C driver configure the hardware properly.

2014-01-04Revert "sparc64: Fix __copy_{to,from}_user_inatomic defines."Dave Kleikamp
This reverts commit 145e1c0023585e0e8f6df22316308ec61c5066b2. This commit broke the behavior of __copy_from_user_inatomic when it is only partially successful. Instead of returning the number of bytes not copied, it now returns 1. This translates to the wrong value being returned by iov_iter_copy_from_user_atomic. xfstests generic/246 and LTP writev01 both fail on btrfs and nfs because of this.

2014-01-04x86, sparse: Do not force removal of __user when calling ↵Steven Rostedt
copy_to/from_user_nocheck() Commit ff47ab4ff3cdd "x86: Add 1/2/4/8 byte optimization to 64bit __copy_{from,to}_user_inatomic" added a "_nocheck" call in between the copy_to/from_user() and copy_user_generic(). As both the normal and nocheck versions of theses calls use the proper __user annotation, a typecast to remove it should not be added.

2014-01-02ARM: bcm2835: add USB controller to device treeStephen Warren
The BCM2835 SoC contains a DWC2 USB controller. Add this to the DT. Set up the pin controller to fully enable the USB controller on the Raspberry Pi. The GPIO setup works because the default output value for GPIO 6 (LAN_RUN/n_reset) just happens to be 1, which enables the USB/LAN chip. Note that you'll need a U-Boot which enables power to the USB controller; search for U-Boot patch "ARM: rpi_b: power on SDHCI and USB HW modules".
