The D1 and T113 are identical in terms of peripherals, they differ only in the architecture of the CPU core, and even share the majority of their DT. Because of that, using the same compatible makes sense. The R329 is a different SoC though, and should have a different compatible string added, especially as there is a difference in the number of channels. D1 and T113s SoCs have one PWM controller with 8 channels. R329 SoC has two PWM controllers in both power domains, one of them has 9 channels (CPUX one) and the other has 6 (CPUS one). Add a device tree binding for them.
