* iio:pressure: Add STMicroelectronics pressures driverDenis CIOCCA2013-06-059-0/+616

| | | | | | | | | | | | | | struct and added support on one-shot sysfs reads to 3 byte channel This patch introduce num_data_channels variable on st_sensors struct to manage different type of channels (size or number) in st_sensors_get_buffer_element function. Removed ST_SENSORS_NUMBER_DATA_CHANNELS and ST_SENSORS_BYTE_FOR_CHANNEL and used struct iio_chan_spec const *ch to catch data. Added 3 byte channel data support on one-shot reads.

| | | | | | | | | | Switching from one platform device registering a lot of triggers to one for each trigger simplifies the code somewhat. It would be relatively unusual to have more than a couple of such devices registered so this change will not result in much additional overhead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Octeon USB HCD. Tested on EdgeRouter Lite with USB mass storage. The driver has been extracted from GPL sources of EdgeRouter Lite firmware (based on Linux 2.6.32.13). Some minor fixes and cleanups have been done to make it work with 3.10-rc3. $ uname -a Linux (none) 3.10.0-rc3-edge-00005-g86cb5bc #41 SMP PREEMPT Sat Jun 1 20:41:46 EEST 2013 mips64 GNU/Linux $ modprobe octeon-usb [ 37.971683] octeon_usb: module is from the staging directory, the quality is unknown, you have been warned.

| | | | | | | | | | | | The timeout detection implemented in this driver isn't very robust. Although the USB interrupt transfer was successful, the polling thread often reported timeouts because the 50ms had expired before it got scheduled, and the SD card wasn't detected. Increasing it to 100ms, as used in other places of this driver, makes it work.

This allows us to fix the server-side timestamp setting in the future. - remove attr_unpack() and convert the flags from MDS_ATTR_ to LA_* directly in mdt_attr_valid_xlate() instead. - improve sanityn.sh test_23().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to avoid compatibility issues with older ChangeLog consumers, change the new CL_LAYOUT record to use the value previously assigned to CL_IOCTL. The CL_IOCTL type was never used anywhere, and it didn't really make any sense as a ChangeLog record, since it could really mean anything at all. The changelog_show_cb() function is renamed to changelog_kkuc_cb(), since it is really about consuming the ChangeLog and passing it up to the kernel-user-coms interface. At some point we should consider to implement a DBUS-based ChangeLog interface as well. The changelog_kkuc_cb() "sanity check" on cr_type was removed, since there is no reason the client kernel needs to know every record type that is being passed to userspace. It is up to the client tool to determine what records that it can process.
