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.
