Convert the Renesas H8/300 Timer Pulse Unit Device Tree binding documentation to json-schema. Correct clock-names, as "peripheral_clk" is the name of the supplier, and all users use "fck". Note that there are two different bindings for the TPU, both using "renesas,tpu": this one for using the TPU as a clock source (used on H8/300), and a second use for using the TPU as a PWM controller (used on ARM). To avoid conflicts, both bindings are marked with the appropriate "select" logic, to check for the absence respectively presence of the "#pwm-cells" property.

The TPU is a 16bit timer/counter with configurable clock inputs and
|
|
programmable compare match.
|
|
This implementation supports only cascade mode.
