title: NXP i.MX PWM over RPMSG driver
maintainers:
- Clark Wang <xiaoning.wang@nxp.com>
description: |
Acore may need to use some TPM resources of Mcore on some SoC platforms.
This driver provide a protocol to send pwm request through RPMSG to
Mcore and control the TPM modules on Mcore.
Mcore will operate its TPM modules according to the Acore request.
