[PATCH 0/2] pwm: some improvements to sysfs interface

From: Aurelio Colosimo
Date: Tue Aug 05 2014 - 11:12:52 EST


This set of patches adds two more features in pwm sysfs, which I
developed for the driver of my pwm device (a virtualization of
AVR pwm outputs, not submitted to mainline yet):

- an optional static name for each pwm device, so that driver develop
can give a name to the output itself, in a similar way as gpio system
does;

- the attribute 'max', and the attribute 'resolution', in
nanoseconds, specific for each pwm device.

Each new field is initialized with a default (meaningful) value;
anyway, if desired, pwm drivers maintainers should fix their
drivers in order to use the new fields.

Aurelio Colosimo (2):
pwm: new field name added to pwm_device
pwm: new fields, max and resolution, added to sysfs
