Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver specific changes from Olof Johansson:
"A collection of mostly SoC-specific driver updates:
- a handful of pincontrol and setup changes
- new drivers for hwmon and reset controller for vexpress
- timing support updates for OMAP (gpmc and other interfaces)
- plus a collection of smaller cleanups"

16 | Description | ||
17 | ----------- | ||
18 | |||
19 | Versatile Express platform (http://www.arm.com/versatileexpress/) is a | ||
20 | reference & prototyping system for ARM Ltd. processors. It can be set up | ||
21 | from a wide range of boards, each of them containing (apart of the main | ||
22 | chip/FPGA) a number of microcontrollers responsible for platform | ||
23 | configuration and control. Theses microcontrollers can also monitor the | ||
24 | board and its environment by a number of internal and external sensors, | ||
25 | providing information about power lines voltages and currents, board | ||
26 | temperature and power usage. Some of them also calculate consumed energy | ||
27 | and provide a cumulative use counter. | ||
28 | |||
29 | The configuration devices are _not_ memory mapped and must be accessed | ||
30 | via a custom interface, abstracted by the "vexpress_config" API. | ||
31 | |||
32 | As these devices are non-discoverable, they must be described in a Device | ||
33 | Tree passed to the kernel. Details of the DT binding for them can be found | ||
34 | in Documentation/devicetree/bindings/hwmon/vexpress.txt. | ||
