[PATCH v2 2/2] dpll: zl3073x: recognize the ZL30643 chip ID (0x0E3B)
From: Vincent Jardin via B4 Relay
Date: Thu Jul 30 2026 - 14:21:56 EST
From: Vincent Jardin <vjardin@xxxxxxx>
The Microchip ZL30643 is a 3-channel ZL3064x line-card part that is
register compatible with the ZL30733. Only the runtime chip-ID table
needs the 0x0E3B entry so the probe resolves the channel count (3)
and flags.
The ZL3073X_FLAG_REF_PHASE_COMP_32 flag applies unchanged: the
ref_phase path
dpll_meas_ctrl::en -> ref_phase_0P/0N
-> ref_phase_offset_compensation -> ref_phase_err_read_rqst
is identical between ZL3064x and ZL3073x. No new device flag is needed.
Test: 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
