For most regulators, the regulator_stop() method can be transformed to regulator disable. But, in some cases, we needs to maintain shared data across multiple regulators (e.g. single GPIO pin which works as enable for multiple regulates). In this case, the implementation of regulator should perform his own enable counting therefore it is necessary to distinguish between the regulator enable/disable method (which increments/decrements enable counter for shared resource) and regulator stop method (which don't affect it). So: - add regnode_stop() method to regulator framework and default it to regnode_enable(..., false, ...) - implement it in regulator_fixed with proper enable counting. While I'm in, also fix handling of always_on property. If any of regulators sharing same GPIO pin have it enabled, then none of them can disable regulator. Tested by: kevans MFC after: 3 weeks

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
