From: Vincent Jardin <redacted>
Register the Microchip ZL30643 (chip ID 0x0E3B), it is a 3 DPLL channel
of the ZL3073x family.
Once register, for instance, we get:
devlink dev param set spi/spi0.0 name clock_id value 3733 cmode driverinit
devlink dev reload spi/spi0.0
devlink dev param set spi/spi2.1 name clock_id value 3643 cmode driverinit
devlink dev reload spi/spi2.1
dpll device show | grep clock-id
clock-id: 3733
clock-id: 3733
clock-id: 3733
clock-id: 3643
clock-id: 3643
clock-id: 3643
