16   Unlike most other PWM controllers, the SiFive PWM controller currently
21   numbers can be found here -

28       - const: sifive,fu540-c000-pwm
29       - const: sifive,pwm0
31       Should be "sifive,<chip>-pwm" and "sifive,pwm<version>". Supported
32       compatible strings are "sifive,fu540-c000-pwm" for the SiFive PWM v0
33       as integrated onto the SiFive FU540 chip, and "sifive,pwm0" for the
34       SiFive PWM v0 IP block with no chip integration tweaks.
35       Please refer to sifive-blocks-ip-versioning.txt for details.
