[PATCH 2/2] dpll: zl3073x: add ZL30643 chip support

From: Vincent Jardin via B4 Relay

Date: Thu Jul 23 2026 - 19:09:47 EST


From: Vincent Jardin <vjardin@xxxxxxx>

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
