I don't like it in this form. On the constructive side I can propose at least two ways to solve: a) introduce a PWM as a pin mode; move pca953x to pin control; use this mode with PWM driver being separated from the pin control; b) introduce an MFD that provides two parts for this GPIO & PWM. Personally I would go with a) as I know at least one more pin controller which will get an advantage of this (and it's definitely not an MFD). If GPIO / pin control maintainers consider this okay, I will rest my case, but see above... -- With Best Regards, Andy Shevchenko
