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
