nxp,imx-tmr

Vendor: NXP Semiconductors

Note

An implementation of a driver matching this compatible is available in drivers/counter/counter_mcux_qtmr.c.

Description

NXP MCUX Quad Timer Channel. Each channel of each quad timer can operate independently and hence will be realized as a separate counter device
