[PATCH v4 3/8] dt-bindings: clock: brcm,kona-ccu: Add BCM21664 and BCM281xx bus clocks
From: Artur Weber
Date: Tue Mar 18 2025 - 04:16:05 EST
Add bus clocks corresponding to peripheral clocks currently supported
by the BCM21664 and BCM281xx clock drivers and add the relevant clock
IDs to the dt-bindings headers (bcm21664.h, bcm281xx.h).
Signed-off-by: Artur Weber <aweber.kernel@xxxxxxxxx>

Changes in v4:
- Squash BCM21664 and BCM281xx bus clock bindings commits
