I did clk_enable -> clk_prepare_enable conversion, as described in
another email.

I got occasional error reading:

root at n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input
20.0
root at n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input
cat: /sys/class/hwmon/hwmon0/device/temp_input: Input/output error
root at n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input
20.0

Nothing in dmesg. It takes few tries to reproduce..

On other attempt, it hung hard:

root at n900:~# cat /sys/class/hwmon/hwmon0/device/temp_input ; cat
/sys/class/hwmon/hwmon0/device/temp_input  ;cat
/sys/class/hwmon/hwmon0/device/temp_input ; cat
/sys/class/hwmon/hwmon0/device/temp_input
17.0
17.0
