For some reason, the select input of pin function USB_OTG_ID is not implemented via a regular select input register but using the bit USB_OTG_ID_ SEL (shift 13) of IOMUXC_GPR1 register (offset 0x4). As per the workaround for such quirk implemented in pinctrl driver, we need to compose the input_val cell as below. 31 23 15 7 0 | 0xff | shift | width | select | Thus, we have 0xff0d0100 for MX6QDL_PAD_ENET_RX_ER__USB_OTG_ID and 0xff0d0101 for MX6QDL_PAD_GPIO_1__USB_OTG_ID in input_val cell.

Convert mx23/mx28 dts filed to use the pinctrl header files. NOTE: During automatic conversion of these files to use the pinconfig definitions an inconsistency has been found in: arch/arm/boot/dts/imx28-apx4devkit.dts According to the comment the function for pad SSP2_SS0 should have been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131 represents: MX28_PAD_SSP2_SS0__AUART3_TX I used the later (though probably wrong) definition because that's what is actually being used in the DTB.

Remove the list of possible pin configurations from the documentation file and create header files containing those definitions. This eliminates the need for error-prone manual lookup of those values in the documentation and guarantees consistency between the human readable representation of the pad function in the .dts file and the actual binary value used in DT.

Merge tag 'iio-fixes-for-3.12a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First round of IIO fixes for 3.12 A series of wrong 'struct dev' assumptions in suspend/resume callbacks following on from this issue being identified in a new driver review. One to watch out for in future. A number of driver specific fixes 1) at91 - fix a overflow in clock rate computation 2) dummy - Kconfig dependency issue 3) isl29018 - uninitialized value 4) hmc5843 - measurement conversion bug introduced by recent cleanup. 5) ade7854-spi - wrong return value. Some IIO core fixes 1) Wrong value picked up for event code creation for a modified channel 2) A null dereference on failure to initialize a buffer after no buffer has been in use, when using the available_scan_masks approach. 3) Sampling not stopped when a device is removed. Effects forced removal such as hot unplugging. 4) Prevent device going away if a chrdev is still open in userspace. 5) Prevent race on chardev opening and device being freed. 6) Add a missing iio_buffer_init in the call back buffer. These last few are the first part of a set from Lars-Peter Clausen who has been taking a closer look at our removal paths and buffer handling than anyone has for quite some time.

Users have been complaining of the uuid tree stuff warning that there is no uuid root when trying to do snapshot operations. This is because if you mount -o ro we will not create the uuid tree. But then if you mount -o rw,remount we will still not create it and then any subsequent snapshot/subvol operations you try to do will fail gloriously. Fix this by creating the uuid_root on remount rw if it was not already there. Thanks, Signed-off-by:

btrfs_ioctl_file_extent_same() uses __put_user_unaligned() to copy some data back to it's argument struct. Unfortunately, not all architectures provide __put_user_unaligned(), so compiles break on them if btrfs is selected. Instead, just copy the whole struct in / out at the start and end of operations, respectively. Signed-off-by:

Commit 2bc55652 (Btrfs: don't update atime on RO subvolumes) ensures that the access time of an inode is not updated when the inode lives in a read-only subvolume. However, if a directory on a read-only subvolume is accessed, the atime is updated. This results in a write operation to a read-only subvolume. I believe that access times should never be updated on read-only subvolumes. To reproduce: # mkfs.btrfs -f /dev/dm-3 (...) # mount /dev/dm-3 /mnt # btrfs subvol create /mnt/sub Create subvolume '/mnt/sub' # mkdir /mnt/sub/dir # echo "abc" > /mnt/sub/dir/file # btrfs subvol snapshot -r /mnt/sub /mnt/rosnap Create a readonly snapshot of '/mnt/sub' in '/mnt/rosnap' # stat /mnt/rosnap/dir File: `/mnt/rosnap/dir' Size: 8 Blocks: 0 IO Block: 4096 directory Device: 16h/22d Inode: 257 Links: 1 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2013-09-11 07:21:49.389157126 -0400 Modify: 2013-09-11 07:22:02.330156079 -0400 Change: 2013-09-11 07:22:02.330156079 -0400 # ls /mnt/rosnap/dir file # stat /mnt/rosnap/dir File: `/mnt/rosnap/dir' Size: 8 Blocks: 0 IO Block: 4096 directory Device: 16h/22d Inode: 257 Links: 1 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2013-09-11 07:22:56.797151670 -0400 Modify: 2013-09-11 07:22:02.330156079 -0400 Change: 2013-09-11 07:22:02.330156079 -0400 Reported-by:
