Merge tag 'char-misc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH: "Here's the "big" char and misc driver update for 4.9-rc1. Lots of little things here, all over the driver tree for subsystems that flow through me. Nothing major that I can discern, full details are in the shortlog. All have been in the linux-next tree with no reported issues" * tag 'char-misc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (144 commits) drivers/misc/hpilo: Changes to support new security states in iLO5 FW at25: fix debug and error messaging misc/genwqe: ensure zero initialization vme: fake: remove unexpected unlock in fake_master_set() vme: fake: mark symbols static where possible spmi: pmic-arb: Return an error code if sanity check fails Drivers: hv: get rid of id in struct vmbus_channel Drivers: hv: make VMBus bus ids persistent mcb: Add a dma_device to mcb_device mcb: Enable PCI bus mastering by default mei: stop the stall timer worker if not needed clk: probe common clock drivers earlier vme: fake: fix build for 64-bit dma_addr_t ttyprintk: Neaten and simplify printing mei: me: add kaby point device ids coresight: tmc: mark symbols static where possible coresight: perf: deal with error condition properly Drivers: hv: hv_util: Avoid dynamic allocation in time synch fpga manager: Add hardware dependency to Zynq driver Drivers: hv: utils: Support TimeSync version 4.0 protocol samples. ...

-What: /sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input
-Date: June 2010
-Contact: Christoph Mair <christoph.mair@gmail.com>
-Description: Start a pressure measurement and read the result. Values
- represent the ambient air pressure in pascal (0.01 millibar).
-
- Reading: returns the current air pressure.
-
-
-What: /sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input
-Date: June 2010
-Contact: Christoph Mair <christoph.mair@gmail.com>
-Description: Measure the ambient temperature. The returned value represents
- the ambient temperature in units of 0.1 degree celsius.
-
- Reading: returns the current temperature.
-
-
-What: /sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling
-Date: June 2010
-Contact: Christoph Mair <christoph.mair@gmail.com>
-Description: Tell the bmp085 to use more samples to calculate a pressure
- value. When writing to this file the chip will use 2^x samples
- to calculate the next pressure value with x being the value
- written. Using this feature will decrease RMS noise and
- increase the measurement time.
-
- Reading: returns the current oversampling setting.
-
- Writing: sets a new oversampling setting.
- Accepted values: 0..3.
