| * | clk: Add PWM clock driverPhilipp Zabel2015-04-101-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some board designers, when running out of clock output pads, decide to (mis)use PWM output pads to provide a clock to external components. This driver supports this practice by providing an adapter between the PWM and clock bindings in the device tree. As the PWM bindings specify the period in the device tree, this is a fixed clock.

There are four instances of the FAPLL on dm816x that each have three to seven child synthesizers. I've set up the FAPLL as a single fapll.c driver. Later on we could potentially have the PLL code generic. To do that, we would have to consider the following: 1. Setting the PLL to bypass mode also sets the child synthesizers into bypass mode. As the bypass rate can also be generated by the PLL in regular mode, there's no way for the child synthesizers to detect the bypass mode based on the parent clock rate. 2. The PLL registers control the power for each of the child syntheriser. Note that the clocks are currently still missing the set_rate implementation so things are still running based on the bootloader values. That's OK for now as most of the outputs have dividers and those can be set using the existing TI component clock code. I have verified that the extclk rates are correct for a few clocks, so adding the set_rate support should be fairly trivial later on.
