Date: January 2016
KernelVersion: 4.6
Contact: Wolfram Sang <wsa@the-dreams.de>
Description:
Reading the file will give you a list of masters which can be
selected for a demultiplexed bus. The format is
"<index>:<name>". Example from a Renesas Lager board:
This file selects the active I2C master for a demultiplexed bus.
0:/i2c@e6500000 1:/i2c@e6508000
Write 0 there for the first master, 1 for the second etc. Reading the file will
give you a list with the active master marked. Example from a Renesas Lager
board:
root@Lager:~# cat /sys/devices/platform/i2c@8/cur_master
* 0 - /i2c@9
1 - /i2c@e6520000

but also it allows of more flexibility in the handling of devices during the

Drivers in ->remove() callback should undo the runtime PM changes done
in ->probe(). Usually this means calling pm_runtime_disable(),
pm_runtime_dont_use_autosuspend() etc.
The user space can effectively disallow the driver of the device to power manage
it at run time by changing the value of its /sys/devices/.../power/control
attribute to "on", which causes pm_runtime_forbid() to be called. In principle,
