This patch exports the smartreflex efuse values for all 5 OPPs via
sysfs. This can be useful to track down silicon specific problems.
Signed-off-by: Peter 'p2' De Schrijver peter.de-schrij...@nokia.com
These should be exported via debugfs instead of sysfs.
Also, the SR rewrite is underway and will be merged shortly, so I
recommend waiting until that is in place before we add this. Unless
Nishanth wants to add it sooner.
